141-997: The Gulf Coast of the United States , also known as the Gulf South or the South Coast , is the coastline along the Southern United States where they meet the Gulf of Mexico . The coastal states that have a shoreline on the Gulf of Mexico are Texas , Louisiana , Mississippi , Alabama , and Florida , and these are known as the Gulf States . The economy of the Gulf Coast area is dominated by industries related to energy, petrochemicals, fishing, aerospace, agriculture, and tourism. The large cities of

282-534: A navy and some form of coast guard . Coasts, especially those with beaches and warm water, attract tourists often leading to the development of seaside resort communities. In many island nations such as those of the Mediterranean , South Pacific Ocean and Caribbean , tourism is central to the economy . Coasts offer recreational activities such as swimming, fishing, surfing, boating, and sunbathing . Growth management and coastal management can be

423-478: A challenge for coastal local authorities who often struggle to provide the infrastructure required by new residents, and poor management practices of construction often leave these communities and infrastructure vulnerable to processes like coastal erosion and sea level rise . In many of these communities, management practices such as beach nourishment or when the coastal infrastructure is no longer financially sustainable, managed retreat to remove communities from

564-572: A city with zoning that flooded." On May 16, 2024, a strong derecho caused widespread damage across the city and surrounding metropolitan area. Houston is 165 miles (266 km) east of Austin , 88 miles (142 km) west of the Louisiana border, and 250 miles (400 km) south of Dallas . The city has a total area of 637.4 square miles (1,651 km ); this comprises over 599.59 square miles (1,552.9 km ) of land and 22.3 square miles (58 km ) covered by water. Most of Houston

705-502: A commercial center, forming a symbiosis with its Gulf Coast port, Galveston. Landlocked farmers brought their produce to Houston, using Buffalo Bayou to gain access to Galveston and the Gulf of Mexico. Houston merchants profited from selling staples to farmers and shipping the farmers' produce to Galveston. The great majority of enslaved people in Texas came with their owners from the older slave states. Sizable numbers, however, came through

846-649: A day of groundwater. Houston has four major bayous passing through the city that accept water from the extensive drainage system. Buffalo Bayou runs through Downtown and the Houston Ship Channel , and has three tributaries: White Oak Bayou, which runs through the Houston Heights community northwest of Downtown and then towards Downtown; Brays Bayou , which runs along the Texas Medical Center; and Sims Bayou , which runs through

987-515: A floodplain, a flowing flood-water stream termed a floodway runs through the development area, a most dangerous place to encounter during any future flooding event. Harris County , like other more rural counties, cannot direct developers where to build or not build via land use controls such as a zoning ordinance by Texas law, and instead can only impose general floodplain regulations for enforcement during subdivision approvals and building permit approvals. The 2020 U.S. census determined Houston had

1128-515: A great extent by its long established tourism industry but also by its position as a gateway to the Caribbean and Latin America . As of 2024, Texas and Florida are the second and third most populous states in the nation, respectively. Other areas of the Gulf Coast have benefited less, though economic development fueled by tourism has greatly increased property values along the coast, and is now

1269-611: A large and growing international community. Houston is the most diverse metropolitan area in Texas and has been described as the most racially and ethnically diverse major city in the U.S. It is home to many cultural institutions and exhibits, such as the Houston Museum District and the Houston Theater District . Present-day Houston sits on land that was once occupied by the Karankawa and

1410-441: A mortgage were $ 1,646, and $ 536 without a mortgage. Houston's median gross rent from 2015 to 2019 was $ 1,041. The median household income in 2019 was $ 52,338 and 20.1% of Houstonians lived at or below the poverty line . Houston is a majority-minority city. The Rice University Kinder Institute for Urban Research, a think tank , has described Greater Houston as "one of the most ethnically and culturally diverse metropolitan areas in

1551-655: A much higher capacity for carbon sequestration than many terrestrial ecosystems , and as such can play a critical role in the near-future to help mitigate climate change effects by uptake of atmospheric anthropogenic carbon dioxide . However, the economic importance of coasts makes many of these communities vulnerable to climate change , which causes increases in extreme weather and sea level rise, as well as related issues like coastal erosion , saltwater intrusion , and coastal flooding . Other coastal issues, such as marine pollution , marine debris , coastal development, and marine ecosystem destruction, further complicate

1692-454: A population of 2,304,580. In 2017, the census-estimated population was 2,312,717, and in 2018 it was 2,325,502. An estimated 600,000 undocumented immigrants resided in the Houston area in 2017, comprising nearly 9% of the city's metropolitan population. At the 2010 United States census , Houston had a population of 2,100,263 residents, up from the city's 2,396 at the 1850 census . Per

1833-532: A population of 2,314,157 in 2023, Houston is the fourth-most populous city in the United States after New York City , Los Angeles , and Chicago , and the sixth-most populous city in North America . Houston is the southeast anchor of the greater megaregion known as the Texas Triangle . Comprising a land area of 640.4 square miles (1,659 km ), Houston is the ninth-most expansive city in

1974-653: A proper name to the coast of the Ligurian Sea , in the form riviera ligure , then shortened to riviera . Historically, the Ligurian Riviera extended from Capo Corvo (Punta Bianca) south of Genoa , north and west into what is now French territory past Monaco and sometimes as far as Marseilles . Today, this coast is divided into the Italian Riviera and the French Riviera , although

2115-435: A provider of sediment for coastlines of tropical islands. Like the ocean which shapes them, coasts are a dynamic environment with constant change. The Earth 's natural processes, particularly sea level rises , waves and various weather phenomena, have resulted in the erosion , accretion and reshaping of coasts as well as flooding and creation of continental shelves and drowned river valleys ( rias ). More and more of

2256-742: A severe danger to the valuable but fragile ecosystems of the Gulf Coast. The following table lists the 11 largest core-based statistical areas along the Gulf Coast. International destinations Coast Coasts are important zones in natural ecosystems , often home to a wide range of biodiversity . On land, they harbor important ecosystems such as freshwater or estuarine wetlands , which are important for bird populations and other terrestrial animals . In wave-protected areas, they harbor salt marshes , mangroves or seagrasses , all of which can provide nursery habitat for fin fish , shellfish , and other aquatic animals . Rocky shores are usually found along exposed coasts and provide habitat for

2397-482: A shelter to more than 150,000 people from New Orleans, who evacuated from Hurricane Katrina . One month later, about 2.5 million Houston-area residents evacuated when Hurricane Rita approached the Gulf Coast , leaving little damage to the Houston area. This was the largest urban evacuation in the history of the United States. In May 2015, seven people died after 12 inches of rain fell in 10 hours during what

2538-456: A shoreline configuration. Swash is the shoreward flow after the break, backwash is the water flow back down the beach. The relative strength of flow in the swash and backwash determines what size grains are deposited or eroded. This is dependent on how the wave breaks and the slope of the shore. Depending on the form of the breaking wave, its energy can carry granular material up the beach and deposit it, or erode it by carrying more material down

2679-425: A slightly different way in discussions of legal and economic boundaries (see territorial waters and international waters ) or when considering the geography of coastal landforms or the ecological systems operating through the continental shelf ( marine coastal ecosystems ). The research on coastal waters often divides into these separate areas too. The dynamic fluid nature of the ocean means that all components of

2820-649: A tropical climate. Much of the year is warm to hot along the Gulf Coast, while the three winter months bring periods of cool (or rarely, cold) weather mixed with mild temperatures. The area is highly vulnerable to hurricanes as well as floods and severe thunderstorms . Much of the Gulf Coast has a summer precipitation maximum, with July or August commonly the wettest month due to the combination of frequent summer thunderstorms produced by relentless heat and humidity, and tropical weather systems, including tropical depressions, tropical storms, and hurricanes , while winter and early spring rainfall also can be heavy. This pattern

2961-529: A wide range of sessile animals (e.g. mussels , starfish , barnacles ) and various kinds of seaweeds . In physical oceanography , a shore is the wider fringe that is geologically modified by the action of the body of water past and present, while the beach is at the edge of the shore, representing the intertidal zone where there is one. Along tropical coasts with clear, nutrient-poor water, coral reefs can often be found between depths of 1–50 m (3.3–164.0 ft). According to an atlas prepared by

3102-541: Is a coastline that has experienced a fall in sea level, because of either a global sea-level change, or local uplift. Emergent coastlines are identifiable by the coastal landforms , which are above the high tide mark, such as raised beaches . In contrast, a submergent coastline is one where the sea level has risen, due to a global sea-level change, local subsidence , or isostatic rebound . Submergent coastlines are identifiable by their submerged, or "drowned" landforms, such as rias (drowned valleys) and fjords According to

3243-593: Is also home to buildings designed by noted architects I. M. Pei , César Pelli , and Philip Johnson. In the late 1990s and early 2000s, a mini-boom of midrise and highrise residential tower construction occurred, with several over 30 stories tall. Since 2000 over 30 skyscrapers have been developed in Houston; all told, 72 high-rises tower over the city, which adds up to about 8,300 units. In 2002, Uptown had more than 23 million square feet (2,100,000 m ) of office space with 16 million square feet (1,500,000 m ) of class A office space . Houston's climate

3384-554: Is classified as humid subtropical ( Cfa in the Köppen climate classification system ), typical of the Southern United States . While not in Tornado Alley , like much of Northern Texas , spring supercell thunderstorms sometimes bring tornadoes to the area. Prevailing winds are from the south and southeast during most of the year, which bring heat and tropical moisture from the nearby Gulf of Mexico and Galveston Bay. During

3525-528: Is connected to marine pollution which can occur from a number of sources: Marine debris (garbage and industrial debris); the transportation of petroleum in tankers , increasing the probability of large oil spills ; small oil spills created by large and small vessels, which flush bilge water into the ocean. Marine pollution occurs when substances used or spread by humans, such as industrial , agricultural and residential waste , particles , noise , excess carbon dioxide or invasive organisms enter

3666-461: Is evident in southern cites as Houston , New Orleans , Mobile, Alabama , and Pensacola, Florida . However, the central and southern Florida peninsula and South Texas has a pronounced winter dry season, as at Tampa and Fort Myers . On the central and southern Texas coast, winter, early spring and mid-summer are markedly drier, and September is the wettest month on average at Corpus Christi and Brownsville, Texas . Tornadoes are infrequent at

3807-415: Is extremely important to geologists. These provide vital clues for reconstructing the geography of ancient continents ( paleogeography ). The locations of these beds show the extent of ancient seas at particular points in geological time, and provide clues to the magnitudes of tides in the distant past. Sediments deposited in the shoreface are preserved as lenses of sandstone in which the upper part of

3948-564: Is intersected by numerous rivers, the largest of which is the Mississippi River . Much of the land along the Gulf Coast is, or was, marshland . Ringing the Gulf Coast is the Gulf Coastal Plain , which reaches from Southern Texas to the western Florida Panhandle , while the western portions of the Gulf Coast are made up of many barrier islands and peninsulas , including the 130-mile (210 km) Padre Island along

4089-568: Is known as the Memorial Day Flood. Eight people died in April 2016 during a storm that dropped 17 inches of rain. The worst came in late August 2017, when Hurricane Harvey stalled over southeastern Texas, much like Tropical Storm Allison did sixteen years earlier, causing severe flooding in the Houston area, with some areas receiving over 50 inches (1,300 mm) of rain. The rainfall exceeded 50 inches in several areas locally, breaking

4230-408: Is more important. Macrotidal coasts lack barrier islands and lagoons , and are characterized by funnel-shaped estuaries containing sand ridges aligned with tidal currents. Wave action is much more important for determining bedforms of sediments deposited along mesotidal and microtidal coasts than in macrotidal coasts. Waves erode coastline as they break on shore releasing their energy; the larger

4371-423: Is moved along the coastline by the waves. This forms an abrasion or cliffed coast . Sediment deposited by rivers is the dominant influence on the amount of sediment located in the case of coastlines that have estuaries. Today, riverine deposition at the coast is often blocked by dams and other human regulatory devices, which remove the sediment from the stream by causing it to be deposited inland. Coral reefs are

4512-507: Is on the gulf coastal plain , and its vegetation is classified as Western Gulf coastal grasslands while further north, it transitions into a subtropical jungle, the Big Thicket . Much of the city was built on forested land, marshes, or swamps, and all are still visible in surrounding areas. Flat terrain and extensive greenfield development have combined to worsen flooding. Downtown stands about 50 feet (15 m) above sea level, and

4653-556: Is the most populous city in the U.S. state of Texas and the Southern United States . Located in Southeast Texas near Galveston Bay and the Gulf of Mexico , it is the seat of Harris County ; as well as the principal city of the Greater Houston metropolitan area, the fifth-most populous metropolitan statistical area in the United States and the second-most populous in Texas after Dallas–Fort Worth . With

4794-533: Is the 64-floor, 901-foot (275 m)-tall, Philip Johnson and John Burgee designed landmark Williams Tower (known as the Transco Tower until 1999). At the time of construction, it was believed to be the world's tallest skyscraper outside a central business district. The new 20-story Skanska building and BBVA Compass Plaza are the newest office buildings built in Uptown after 30 years. The Uptown District

4935-412: Is the counterintuitive observation that the coastline of a landmass does not have a well-defined length. This results from the fractal curve –like properties of coastlines; i.e., the fact that a coastline typically has a fractal dimension . Although the "paradox of length" was previously noted by Hugo Steinhaus , the first systematic study of this phenomenon was by Lewis Fry Richardson , and it

5076-488: Is the largest city in the United States without formal zoning regulations, it has developed similarly to other Sun Belt cities because the city's land use regulations and legal covenants have played a similar role. Regulations include mandatory lot size for single-family houses and requirements that parking be available to tenants and customers. In 1998, Houston relaxed its mandatory lot sizes from 5,000 square feet to 3,500 square feet, which spurred housing construction in

5217-631: Is the only metropolitan area with less than ten million citizens where such a CO 2 dome can be detected by satellites. Because of Houston's wet season and proximity to the Gulf Coast , the city is prone to flooding from heavy rains; the most notable flooding events include Tropical Storm Allison in 2001 and Hurricane Harvey in 2017, along with most recent Tropical Storm Imelda in 2019 and Tropical Storm Beta in 2020. In response to Hurricane Harvey, Mayor Sylvester Turner of Houston initiated plans to require developers to build homes that will be less susceptible to flooding by raising them two feet above

5358-418: Is the tallest structure in Texas, 19th tallest building in the United States, and was previously 85th-tallest skyscraper in the world, based on highest architectural feature. In 1983, the 71-floor, 992-foot (302 m)-tall Wells Fargo Plaza (formerly Allied Bank Plaza) was completed, becoming the second-tallest building in Houston and Texas. Based on highest architectural feature, it is the 21st-tallest in

5499-515: Is ubiquitous in Houston; in 1981, annual spending on electricity for interior cooling exceeded $ 600 million (equivalent to $ 2.01 billion in 2023), and by the late 1990s, approximately 90% of Houston homes featured air conditioning systems. The record highest temperature recorded in Houston is 109 °F (43 °C) at Bush Intercontinental Airport, on four occasions: September 4, 2000; August 27, 2011; and August 24 and August 27, 2023. Houston has mild winters, with occasional cold spells. In January,

5640-405: The 500-year floodplain . Hurricane Harvey damaged hundreds of thousands of homes and dumped trillions of gallons of water into the city. In places this led to feet of standing water that blocked streets and flooded homes. The Houston City Council passed this regulation in 2018 with a vote of 9–7. Had these floodplain development rules had been in place all along, it is estimated that 84% of homes in

5781-462: The Aegean Sea . The following articles describe some coastal landforms: "Coastal waters" (or "coastal seas") is a rather general term used differently in different contexts, ranging geographically from the waters within a few kilometers of the coast, through to the entire continental shelf which may stretch for more than a hundred kilometers from land. Thus the term coastal waters is used in

5922-479: The American Lung Association rating the metropolitan area's ozone level twelfth on the "Most Polluted Cities by Ozone" in 2017, after major cities such as Los Angeles , Phoenix , New York City , and Denver . The industries along the ship channel are a major cause of the city's air pollution. The rankings are in terms of peak-based standards, focusing strictly on the worst days of the year;

6063-701: The Atakapa indigenous peoples for at least 2,000 years before the first known settlers arrived. These tribes are almost nonexistent today; this was most likely caused by foreign disease, and competition with various settler groups in the 18th and 19th centuries. However, the land then remained largely uninhabited from the late 1700s until settlement in the 1830s. The Allen brothers— Augustus Chapman and John Kirby —explored town sites on Buffalo Bayou and Galveston Bay . According to historian David McComb, "[T]he brothers, on August 26, 1836, bought from Elizabeth E. Parrott, wife of T.F.L. Parrott and widow of John Austin,

6204-662: The Atlantic seaboard and the fourth largest in the U.S. overall. Two major events were turning points in the earlier history of the Gulf Coast region. The first was the American Civil War , which caused severe damage to some economic sectors in the South , including the Gulf Coast. The second event was the Galveston Hurricane of 1900 . At the end of the 19th century Galveston was, with New Orleans, one of

6345-545: The Battle of Galveston . After the Civil War, Houston businessmen initiated efforts to widen the city's extensive system of bayous so the city could accept more commerce between Downtown and the nearby port of Galveston. By 1890, Houston was the railroad center of Texas. In 1900, after Galveston was struck by a devastating hurricane , efforts to make Houston into a viable deep-water port were accelerated. The following year,

6486-564: The Houston Dynamo soccer team was formed. In 2017 , the Houston Astros won their first World Series . Flooding has been a recurring problem in the Houston area. In June 2001, Tropical Storm Allison dumped up to 40 inches (1,000 mm) of rain on parts of Houston, causing what was then the worst flooding in the city's history and billions of dollars in damage, and killed 20 people in Texas. In August 2005, Houston became

6627-726: The Houston Ship Channel , and the Texas oil boom . In the mid-20th century, Houston's economy diversified, as it became home to the Texas Medical Center —the world's largest concentration of healthcare and research institutions—and NASA 's Johnson Space Center , home to the Mission Control Center . Since the late 19th century, Houston's economy has had a broad industrial base in energy , manufacturing , aeronautics, and transportation . Leading in healthcare sectors and building oilfield equipment, Houston has

6768-538: The Interstate 610 loop . The "Inner Loop" encompasses a 97-square-mile (250 km ) area which includes Downtown, pre–World War II residential neighborhoods and streetcar suburbs , and newer high-density apartment and townhouse developments. Outside the loop, the city's typology is more suburban , though many major business districts—such as Uptown , Westchase , and the Energy Corridor —lie well outside

6909-463: The Port of Houston are two of the ten busiest ports in the world by cargo volume. As of 2004, seven of the top ten busiest ports in the U.S. are on the Gulf Coast. The discovery of oil and gas deposits along the coast and offshore, combined with easy access to shipping, have made the Gulf Coast the heart of the U.S. petrochemical industry . The coast contains nearly 4,000 oil platforms . Besides

7050-456: The US EPA considers this region to extend much further offshore. "Coastal waters" has specific meanings in the context of commercial coastal shipping , and somewhat different meanings in the context of naval littoral warfare . Oceanographers and marine biologists have yet other takes. Coastal waters have a wide range of marine habitats from enclosed estuaries to the open waters of

7191-617: The United Nations , about 44% of the human population lives within 150 km (93 mi) of the sea as of 2013 . Due to its importance in society and its high population concentrations, the coast is important for major parts of the global food and economic system, and they provide many ecosystem services to humankind. For example, important human activities happen in port cities. Coastal fisheries (commercial, recreational, and subsistence) and aquaculture are major economic activities and create jobs, livelihoods, and protein for

7332-686: The Western Interior Seaway , a shallow sea that flooded central North America during the late Cretaceous Period (about 100 to 66 million years ago). These are beautifully exposed along the Book Cliffs of Utah and Colorado . The following articles describe the various geologic processes that affect a coastal zone: Larger animals that live in coastal areas include puffins , sea turtles and rockhopper penguins , among many others. Sea snails and various kinds of barnacles live on rocky coasts and scavenge on food deposited by

7473-482: The capital of the Texas Republic in the late 1830s, Houston grew steadily into a regional trading center for the remainder of the 19th century. The 20th century brought a convergence of economic factors that fueled rapid growth in Houston, including a burgeoning port and railroad industry, the decline of Galveston as Texas's primary port following a devastating 1900 hurricane , the subsequent construction of

It is a combination of chemicals and trash, most of which comes from land sources and is washed or blown into the ocean. This pollution results in damage to the environment, to the health of all organisms, and to economic structures worldwide. Since most inputs come from land, either via

7755-596: The ocean . Floating oceanic debris tends to accumulate at the center of gyres and on coastlines, frequently washing aground, when it is known as beach litter or tidewrack. Deliberate disposal of wastes at sea is called ocean dumping . Naturally occurring debris, such as driftwood and drift seeds , are also present. With the increasing use of plastic , human influence has become an issue as many types of (petrochemical) plastics do not biodegrade quickly, as would natural or organic materials. The largest single type of plastic pollution (~10%) and majority of large plastic in

Air pollution is also a contributing factor by carrying off iron, carbonic acid, nitrogen , silicon, sulfur, pesticides or dust particles into the ocean. The pollution often comes from nonpoint sources such as agricultural runoff , wind-blown debris , and dust. These nonpoint sources are largely due to runoff that enters

8037-604: The 100-year and 500-year floodplains would have been spared damage. In a recent case testing these regulations, near the Brickhouse Gulley, an old golf course that long served as a floodplain and reservoir for floodwaters, announced a change of heart toward intensifying development. A nationwide developer, Meritage Homes , bought the land and planned to develop the 500-year floodplain into 900 new residential homes. Their plan would bring in $ 360 million in revenue and boost city population and tax revenue. In order to meet

8178-507: The 1960s, Downtown Houston consisted of a collection of mid-rise office structures. Downtown was on the threshold of an energy industry–led boom in 1970. A succession of skyscrapers was built throughout the 1970s—many by real estate developer Gerald D. Hines —culminating with Houston's tallest skyscraper, the 75-floor, 1,002-foot (305 m)-tall JPMorgan Chase Tower (formerly the Texas Commerce Tower), completed in 1982. It

8742-458: The Gulf Coast was a natural magnet in the South providing access to shipping lanes and both national and international commerce. The development of sugar and cotton production (enabled by slavery ) allowed the South to prosper. By the mid-19th century the city of New Orleans , being situated as a key to commerce on the Mississippi River and in the Gulf, had become the largest U.S. city not on

8883-624: The Gulf Coast was struck by a catastrophic hurricane. Due to its immense size, Hurricane Ike caused devastation from the Louisiana coastline all the way to the Kenedy County, Texas , region near Corpus Christi . In addition, Ike caused flooding and significant damage along the Mississippi coastline and the Florida Panhandle Ike killed 112 people and left upwards of 300 people missing, never to be found. Hurricane Ike

9024-662: The Gulf Coast. In 2008 floods in Iowa destroyed the local Flood Museum which held materials from the Great Mississippi and Missouri Rivers Flood of 1993 . Before European settlers arrived in the region, the Gulf Coast was home to several pre-Columbian kingdoms which had extensive trade networks with empires such as the Aztecs and the Mississippi Mound Builders. Shark and alligator teeth and shells from

9165-664: The Gulf have been found as far north as Ohio, in the mounds of the Hopewell culture. The first Europeans to settle the Gulf Coast were primarily the French and the Spanish . The Louisiana Purchase (1803), Adams–Onís Treaty (1819) and the Texas Revolution (1835–1836) made the Gulf Coast a part of the United States during the first half of the 19th century. As the U.S. population continued to expand its frontiers westward,

Healthcare has emerged as a major industry in Houston. The Texas Medical Center is now the largest medical complex in the world and employs over 120,000 people. Three new sports stadiums opened downtown in the first decade of

9447-507: The North ; this resulted in an economic boom and produced a key shift in the city's economy toward the energy sector. The increased production of the expanded shipbuilding industry during World War II spurred Houston's growth, as did the establishment in 1961 of NASA's "Manned Spacecraft Center" (renamed the Lyndon B. Johnson Space Center in 1973). This was the stimulus for the development of

9588-399: The Texas coast. These landforms protect numerous bays and inlets providing as a barrier to oncoming waves. The central part of the Gulf Coast, from eastern Texas through Louisiana, consists primarily of marshland. The eastern part of the Gulf Coast, predominantly Florida, is dotted with many bays and inlets. The Gulf Coast climate is humid subtropical, although Southwest Florida features

9729-546: The United Nations has declared 2021–2030 the UN Decade on Ecosystem Restoration , but restoration of coastal ecosystems has received insufficient attention. Since coasts are constantly changing, a coastline's exact perimeter cannot be determined; this measurement challenge is called the coastline paradox . The term coastal zone is used to refer to a region where interactions of sea and land processes occur. Both

10011-581: The United States approximately $ 2.6 billion in relief efforts and caused at least seven deaths. By 2051, the cost of flood damage is expected to increase by 61%, or $ 32 billion. The Gulf Coast is a major center of economic activity. The marshlands along the Louisiana and Texas coasts provide breeding grounds and nurseries for ocean life that drive the fishing and shrimping industries. The Port of South Louisiana ( Metropolitan New Orleans in Laplace ) and

10152-401: The United States. The majority of rainfall occurs between April and October (the wet season of Southeast Texas), when the moisture from the Gulf of Mexico evaporates extensively over the city. Houston has excessive ozone levels and is routinely ranked among the most ozone-polluted cities in the United States. Ground-level ozone, or smog, is Houston's predominant air pollution problem, with

10293-498: The United States. In 2007, Downtown had over 43 million square feet (4,000,000 m ) of office space. Centered on Post Oak Boulevard and Westheimer Road, the Uptown District boomed during the 1970s and early 1980s when a collection of midrise office buildings, hotels, and retail developments appeared along I-610 West. Uptown became one of the most prominent instances of an edge city . The tallest building in Uptown

10434-476: The above, the region features other important industries including aerospace and biomedical research , as well as older industries such as agriculture and — especially since the development of the Gulf Coast beginning in the 1920s and the increase in wealth throughout the United States ;— tourism . Hurricane Katrina and Hurricane Rita have destroyed a number of museums and archives in

10575-571: The average sea level rose by 15–25 cm (6–10 in), with an increase of 2.3 mm (0.091 in) per year since the 1970s. This was faster than the sea level had ever risen over at least the past 3,000 years. The rate accelerated to 4.62 mm (0.182 in)/yr for the decade 2013–2022. Climate change due to human activities is the main cause. Between 1993 and 2018, melting ice sheets and glaciers accounted for 44% of sea level rise , with another 42% resulting from thermal expansion of water . International attention to address

10716-441: The average ozone levels in Houston are lower than what is seen in most other areas of the country, as dominant winds ensure clean, marine air from the Gulf. Excessive man-made emissions in the Houston area led to a persistent increase of atmospheric carbon dioxide over the city. Such an increase, often regarded as "CO 2 urban dome", is driven by a combination of strong emissions and stagnant atmospheric conditions. Moreover, Houston

10857-417: The average wind wave and swell conditions are relatively mild. Low energy coasts typically change slowly, and tend to be depositional environments. High energy coasts are exposed to the direct impact of waves and storms, and are generally erosional environments. High energy storm events can make large changes to a coastline, and can move significant amounts of sediment over a short period, sometimes changing

10998-621: The cities of New Orleans to Tampa. Due to the release of greenhouse gas emissions, glaciers and ice sheets are melting and expanding the oceans. The United States coastlines are projected to rise 1 foot in three decades or between 10 and 12 inches on average by 2050. The Gulf Coast will likely see the biggest change, with sea levels expected to rise between 14 and 18 inches. The Global and Regional Sea Level Rise Report predicted more frequent, major and destructive high tide flooding events along with taller storm surges by 2050 after scientists determined high tide flooding has been "increasingly common" over

11139-403: The city dramatically. Such restrictions have had mixed results. Though some have blamed the city's low density, urban sprawl , and lack of pedestrian-friendliness on these policies, others have credited the city's land use patterns with providing significant affordable housing, sparing Houston the worst effects of the 2008 real estate crisis . The city issued 42,697 building permits in 2008 and

11280-435: The city have a high risk of localized flooding due to flat topography, ubiquitous low- permeability clay-silt prairie soils, and inadequate infrastructure. During the mid-2010s, Greater Houston experienced consecutive major flood events in 2015 ( "Memorial Day" ), 2016 ( "Tax Day" ), and 2017 ( Hurricane Harvey ). Overall, there have been more casualties and property loss from floods in Houston than in any other locality in

11421-608: The city in addition to Downtown , which include Uptown, the Texas Medical Center , Midtown , Greenway Plaza , Memorial City , the Energy Corridor, Westchase , and Greenspoint . Houston had the fifth-tallest skyline in North America (after New York City, Chicago , Toronto and Miami ) and 36th-tallest in the world in 2015. A seven-mile (11 km) system of tunnels and skywalks links Downtown buildings containing shops and restaurants, enabling pedestrians to avoid summer heat and rain while walking between buildings. In

11562-584: The city's aerospace industry. The Astrodome , nicknamed the " Eighth Wonder of the World ", opened in 1965 as the world's first indoor domed sports stadium. During the late 1970s, Houston had a population boom as people from the Rust Belt states moved to Texas in large numbers. The new residents came for numerous employment opportunities in the petroleum industry, created as a result of the Arab oil embargo . With

11703-419: The city. Land in some areas southeast of Houston is sinking because water has been pumped out of the ground for many years. It may be associated with slip along the faults; however, the slippage is slow and not considered an earthquake, where stationary faults must slip suddenly enough to create seismic waves. These faults also tend to move at a smooth rate in what is termed " fault creep ", which further reduces

11844-429: The coast but do occur; however, they occur more frequently in inland portions of Gulf Coast states. Over most of the Gulf Coast from Houston, Texas , eastward, extreme rainfall events are a significant threat, commonly from tropical weather systems, which can bring 4 to 10 or more inches of rain in a single day. In August 2017, Hurricane Harvey made landfall along the central Texas coast, then migrated to and stalled over

11985-461: The coast of Wales and other countries. Coastal fish , also called inshore fish or neritic fish, inhabit the sea between the shoreline and the edge of the continental shelf . Since the continental shelf is usually less than 200 metres (660 ft) deep, it follows that pelagic coastal fish are generally epipelagic fish , inhabiting the sunlit epipelagic zone . Coastal fish can be contrasted with oceanic fish or offshore fish , which inhabit

12126-812: The coast. Estuarine and marine coastal ecosystems are both marine ecosystems . Together, these ecosystems perform the four categories of ecosystem services in a variety of ways: The provisioning services include forest products, marine products, fresh water , raw materials, biochemical and genetic resources. Regulating services include carbon sequestration (contributing to climate change mitigation ) as well as waste treatment and disease regulation and buffer zones. Supporting services of coastal ecosystems include nutrient cycling , biologically mediated habitats and primary production . Cultural services of coastal ecosystems include inspirational aspects, recreation and tourism , science and education. According to one principle of classification, an emergent coastline

12267-567: The continental shelf. Similarly, the term littoral zone has no single definition. It is the part of a sea , lake , or river that is close to the shore . In coastal environments, the littoral zone extends from the high water mark , which is rarely inundated, to shoreline areas that are permanently submerged . Coastal waters can be threatened by coastal eutrophication and harmful algal blooms . The identification of bodies of rock formed from sediments deposited in shoreline and nearshore environments (shoreline and nearshore facies )

12408-555: The deep seas beyond the continental shelves. Many coastal areas are famous for their kelp beds. Kelp is a fast-growing seaweed that can grow up to half a meter a day in ideal conditions. Mangroves , seagrasses , macroalgal beds, and salt marsh are important coastal vegetation types in tropical and temperate environments respectively. Restinga is another type of coastal vegetation. Coasts also face many human-induced environmental impacts and coastal development hazards . The most important ones are: The pollution of coastlines

12549-553: The discovery of oil at the Spindletop oil field near Beaumont prompted the development of the Texas petroleum industry. In 1902, President Theodore Roosevelt approved a $ 1 million improvement project for the Houston Ship Channel. By 1910, the city's population had reached 78,800, almost doubling from a decade before. African Americans formed a large part of the city's population, numbering 23,929 people, which

12690-516: The domestic slave trade. New Orleans was the center of this trade in the Deep South, but slave dealers were in Houston. Thousands of enslaved black people lived near the city before the American Civil War . Many of them near the city worked on sugar and cotton plantations, while most of those in the city limits had domestic and artisan jobs. In 1840, the community established a chamber of commerce, in part to promote shipping and navigation at

12831-537: The erosion of the Rocky Mountains . These sediments consist of a series of sands and clays deposited on decaying organic marine matter, that over time, transformed into oil and natural gas. Beneath the layers of sediment is a water-deposited layer of halite , a rock salt. The porous layers were compressed over time and forced upward. As it pushed upward, the salt dragged surrounding sediments into salt dome formations, often trapping oil and gas that seeped from

12972-499: The first time that May. The Republic of Texas granted Houston incorporation on June 5, 1837, as James S. Holman became its first mayor. In the same year, Houston became the county seat of Harrisburg County (now Harris County). In 1839, the Republic of Texas relocated its capital to Austin . The town suffered another setback that year when a yellow fever epidemic claimed about one life for every eight residents, yet it persisted as

13113-407: The greater Houston area for several days, producing extreme, unprecedented rainfall totals of over 40 inches (1,000 mm) in many areas, unleashing widespread flooding. Climate scientists predict more hurricanes for Florida and the Texas coastline in particular. Earthquakes are extremely rare to the area, but a 6.0 earthquake in the Gulf of Mexico on September 10, 2006, could be felt from

13254-436: The highest point in far northwest Houston is about 150 feet (46 m) in elevation. The city once relied on groundwater for its needs, but land subsidence forced the city to turn to ground-level water sources such as Lake Houston , Lake Conroe , and Lake Livingston . The city owns surface water rights for 1.20 billion U.S. gallons (4.5 Gl) of water a day in addition to 150 million U.S. gallons (570 Ml)

13395-789: The human uses of the coast and threaten coastal ecosystems. The interactive effects of climate change, habitat destruction , overfishing , and water pollution (especially eutrophication ) have led to the demise of coastal ecosystem around the globe. This has resulted in population collapse of fisheries stocks, loss of biodiversity , increased invasion of alien species , and loss of healthy habitats. International attention to these issues has been captured in Sustainable Development Goal 14 "Life Below Water", which sets goals for international policy focused on preserving marine coastal ecosystems and supporting more sustainable economic practices for coastal communities. Likewise,

13536-616: The increase in professional jobs, Houston has become a destination for many college-educated persons, most recently including African Americans in a reverse Great Migration from northern areas. In 1997, Houstonians elected Lee P. Brown as the city's first African American mayor. Houston has continued to grow into the 21st century, with the population increasing 15.7% from 2000 to 2022. Oil and gas have continued to fuel Houston's economic growth, with major oil companies including Phillips 66 , ConocoPhillips , Occidental Petroleum , Halliburton , and ExxonMobil having their headquarters in

13677-516: The major discoveries of oil in Texas and spurred on by further discoveries in the Gulf waters, has been a vehicle for development in the central and western Gulf which has spawned development on a variety of fronts in these regions. Texas in particular has benefited tremendously from this industry over the course of the 20th century and economic diversification has made the state a magnet for population and home to more Fortune 500 companies than any other U.S. state. Florida has grown as well, driven to

13818-410: The majority of coastal human populations. Other coastal spaces like beaches and seaside resorts generate large revenues through tourism . Marine coastal ecosystems can also provide protection against sea level rise and tsunamis . In many countries, mangroves are the primary source of wood for fuel (e.g. charcoal ) and building material. Coastal ecosystems like mangroves and seagrasses have

13959-673: The margins of the continental shelves , make up about 7 percent of the Earth's oceans, but at least 85% of commercially harvested fish depend on coastal environments during at least part of their life cycle. As of October 2010, about 2.86% of exclusive economic zones were part of marine protected areas . The definition of coasts varies. Marine scientists think of the "wet" (aquatic or intertidal ) vegetated habitats as being coastal ecosystems (including seagrass, salt marsh etc.) whilst some terrestrial scientists might only think of coastal ecosystems as purely terrestrial plants that live close to

14100-570: The metro area, and an event on December 7, 2017, which precipitated 0.7 inches (2 cm) of snowfall. Snowfalls of at least 1 inch (2.5 cm) on both December 10, 2008, and December 4, 2009, marked the first time measurable snowfall had occurred in two consecutive years in the city's recorded history. Overall, Houston has seen measurable snowfall 38 times between 1895 and 2018. On February 14 and 15, 1895, Houston received 20 inches (51 cm) of snow, its largest snowfall from one storm on record. The coldest temperature officially recorded in Houston

14241-587: The microplastics go through the water filtration system and into the ocean, but because of their small size they are likely to escape capture by the preliminary treatment screens on wastewater plants. These beads are harmful to the organisms in the ocean, especially filter feeders, because they can easily ingest the plastic and become sick. The microplastics are such a concern because it is difficult to clean them up due to their size, so humans can try to avoid using these harmful plastics by purchasing products that use environmentally safe exfoliates. Between 1901 and 2018,

14382-507: The more resistant rocks erode more slowly, remaining as headlands or outcroppings . Parts of a coastline can be categorised as high energy coast or low energy coast. The distinguishing characteristics of a high energy coast are that the average wave energy is relatively high so that erosion of small grained material tends to exceed deposition, and consequently landforms like cliffs, headlands and wave-cut terraces develop. Low energy coasts are generally sheltered from waves, or in regions where

14523-481: The most developed cities in the region. The city had the third busiest port in the U.S. and its financial district was known as the "Wall Street of the South". Since then the Gulf Coast has been hit with numerous other hurricanes. On August 29, 2005, Hurricane Katrina struck the Gulf Coast as a Category 3 hurricane. It was the most damaging storm in the history of the United States, causing upwards of $ 80 billion in damages, and leaving over 1,800 dead. Again in 2008

14664-611: The national record for rainfall. The damage for the Houston area was estimated at up to $ 125 billion U.S. dollars , and was considered to be one of the worst natural disasters in the history of the United States , with the death toll exceeding 70 people. Houston's lack of zoning laws allowed unregulated building of residential homes and other structures in flood-prone areas. However, it also resulted in more concentrated development in already urban areas than in wetlands and suburbs. Mayor Sylvester Turner tweeted of Hurricane Harvey that "zoning wouldn't have changed anything. We would have been

14805-461: The new floodplain regulations, the developers needed to elevate the lowest floors two feet above the 500-year floodplain, equivalent to five or six feet above the 100-year base flood elevation, and build a channel to direct stormwater runoff toward detention basins. Before Hurricane Harvey, the city had bought $ 10.7 million in houses in this area specifically to take them out of danger. In addition to developing new streets and single-family housing within

14946-491: The newly created port on Buffalo Bayou. By 1860, Houston had emerged as a commercial and railroad hub for the export of cotton. Railroad spurs from the Texas inland converged in Houston, where they met rail lines to the ports of Galveston and Beaumont . During the American Civil War, Houston served as a headquarters for Confederate Major General John B. Magruder , who used the city as an organization point for

15087-423: The normal mean temperature at George Bush Intercontinental Airport is 53 °F (12 °C), with an average of 13 days per year with a low at or below 32 °F (0 °C), occurring on average between December 3 and February 20, allowing for a growing season of 286 days. Twenty-first century snow events in Houston include a storm on December 24, 2004 , which saw 1 inch (3 cm) of snow accumulate in parts of

15228-544: The notional town in honor of Sam Houston, who would become President later that year. They successfully lobbied the Republic of Texas Congress to designate Houston as the temporary capital, agreeing to provide the new government with a state capitol building. About a dozen persons resided in the town at the beginning of 1837, but that number grew to about 1,500 by the time the Texas Congress convened in Houston for

15369-441: The ocean through rivers, but wind-blown debris and dust can also play a role, as these pollutants can settle into waterways and oceans. Pathways of pollution include direct discharge, land runoff, ship pollution , bilge pollution , atmospheric pollution and, potentially, deep sea mining . Marine debris , also known as marine litter, is human-created solid material that has deliberately or accidentally been released in seas or

15510-485: The oceans is discarded and lost nets from the fishing industry. Waterborne plastic poses a serious threat to fish , seabirds , marine reptiles , and marine mammals , as well as to boats and coasts. A growing concern regarding plastic pollution in the marine ecosystem is the use of microplastics. Microplastics are beads of plastic less than 5 millimeters wide, and they are commonly found in hand soaps, face cleansers, and other exfoliators. When these products are used,

15651-544: The past few years due to the rising sea levels. The impacts are expected to be dramatic. Low-lying coastal areas are expected to experience multiple factors, including increased levels of flooding, accelerated erosion, loss of wetlands and low-lying terrestrial ecosystems, and seawater intrusion into freshwater sources. Rising sea level and erosion will also imperil critical habitats for many commercially important fisheries that depend on inshore waters for either permanent residence or nursery area. In 2021 alone rising sea levels cost

15792-485: The port decreased and shipping activities were suspended; however, the war did provide economic benefits for the city. Petrochemical refineries and manufacturing plants were constructed along the ship channel because of the demand for petroleum and synthetic rubber products by the defense industry during the war. Ellington Field , initially built during World War I , was revitalized as an advanced training center for bombardiers and navigators. The Brown Shipbuilding Company

15933-448: The postwar years. In 1945, the M.D. Anderson Foundation formed the Texas Medical Center . After the war, Houston's economy reverted to being primarily port-driven. In 1948, the city annexed several unincorporated areas, more than doubling its size. Houston proper began to spread across the region. In 1950, the availability of air conditioning provided impetus for many companies to relocate to Houston, where wages were lower than those in

16074-448: The region are (from west to east) Brownsville , Corpus Christi , Houston , Galveston , Beaumont , Lake Charles , Lafayette , Baton Rouge , New Orleans , Gulfport , Biloxi , Mobile , Pensacola , Panama City , St. Petersburg , and Tampa . All are the centers or major cities of their respective metropolitan areas and many of which contain large ports . The Gulf Coast is made of many inlets , bays , and lagoons . The coast

16215-505: The risk of an earthquake. The city of Houston was incorporated in 1837 and adopted a ward system of representation shortly afterward, in 1840. The six original wards of Houston are the progenitors of the 11 modern-day geographically oriented Houston City Council districts, though the city abandoned the ward system in 1905 in favor of a commission government , and, later, the existing mayor–council government . Locations in Houston are generally classified as either being inside or outside

16356-416: The sandstone is coarser than the lower part (a coarsening upwards sequence ). Geologists refer to these are parasequences . Each records an episode of retreat of the ocean from the shoreline over a period of 10,000 to 1,000,000 years. These often show laminations reflecting various kinds of tidal cycles. Some of the best-studied shoreline deposits in the world are found along the former western shore of

16497-579: The sea. Some coastal animals are used to humans in developed areas, such as dolphins and seagulls who eat food thrown for them by tourists. Since the coastal areas are all part of the littoral zone , there is a profusion of marine life found just off-coast, including sessile animals such as corals , sponges, starfish, mussels, seaweeds, fishes, and sea anemones . There are many kinds of seabirds on various coasts. These include pelicans and cormorants , who join up with terns and oystercatchers to forage for fish and shellfish. There are sea lions on

16638-401: The seashore (see also estuaries and coastal ecosystems ). While there is general agreement in the scientific community regarding the definition of coast, in the political sphere, the delineation of the extents of a coast differ according to jurisdiction . Government authorities in various countries may define coast differently for economic and social policy reasons. The coastline paradox

16779-427: The second principle of classification, a concordant coastline is a coastline where bands of different rock types run parallel to the shore. These rock types are usually of varying resistance , so the coastline forms distinctive landforms, such as coves. Discordant coastlines feature distinctive landforms because the rocks are eroded by the ocean waves . The less resistant rocks erode faster, creating inlets or bay ;

16920-481: The second-most Fortune 500 headquarters of any U.S. municipality within its city limits. The Port of Houston ranks first in the United States in international waterborne tonnage handled and second in total cargo tonnage handled. Nicknamed the "Bayou City", "Space City", "H-Town", and "the 713 ", Houston has become a global city , with strengths in culture, medicine, and research. The city's population comprises various ethnic and religious backgrounds, as well as

17061-404: The slope than up it. Steep waves that are close together and break with the surf plunging down onto the shore slope expend much of their energy lifting the sediment. The weak swash does not carry it far up the slope, and the strong backwash carries it further down the slope, where it either settles in deeper water or is carried along the shore by a longshore current induced by an angled approach of

17202-515: The south half of the lower league [2,214-acre (896 ha) tract] granted to her by her late husband. They paid $ 5,000 total, but only $ 1,000 of this in cash; notes made up the remainder." This was financed by assets inherited by Augustus's wife, Charlotte Baldwin Allen . The Allen brothers ran their first advertisement for Houston just four days later in the Telegraph and Texas Register , naming

17343-475: The south of Houston and Downtown Houston. The ship channel continues past Galveston and then into the Gulf of Mexico. Houston is a flat, marshy area where an extensive drainage system has been built. The adjoining prairie land drains into the city, which is prone to flooding. Underpinning Houston's land surface are unconsolidated clays, clay shales, and poorly cemented sands up to several miles deep. The region's geology developed from river deposits formed from

17484-421: The summer, temperatures reach or exceed 90 °F (32 °C) an average of 106.5 days per year, including a majority of days from June to September. Additionally, an average of 4.6 days per year reach or exceed 100 °F (37.8 °C). Houston's characteristic subtropical humidity often results in a higher apparent temperature , and summer mornings average over 90% relative humidity . Air conditioning

17625-466: The surrounding porous sands. The thick, rich, sometimes black, surface soil is suitable for rice farming in suburban outskirts where the city continues to grow. The Houston area has over 150 active faults (estimated to be 300 active faults ) with an aggregate length of up to 310 miles (500 km), including the Long Point–Eureka Heights fault system which runs through the center of

17766-758: The terms coast and coastal are often used to describe a geographic location or region located on a coastline (e.g., New Zealand's West Coast , or the East , West , and Gulf Coast of the United States .) Coasts with a narrow continental shelf that are close to the open ocean are called pelagic coast , while other coasts are more sheltered coast in a gulf or bay . A shore , on the other hand, may refer to parts of land adjoining any large body of water, including oceans (sea shore) and lakes (lake shore). The Earth has approximately 620,000 kilometres (390,000 mi) of coastline. Coastal habitats, which extend to

17907-540: The threats of coasts has been captured in Sustainable Development Goal 14 "Life Below Water" which sets goals for international policy focused on preserving marine coastal ecosystems and supporting more sustainable economic practices for coastal communities. Likewise, the United Nations has declared 2021–2030 the UN Decade on Ecosystem Restoration , but restoration of coastal ecosystems has received insufficient attention. Houston, Texas Houston ( / ˈ h juː s t ən / HEW -stən )

18048-599: The urban core. In addition to Interstate 610, two additional loop highways encircle the city: Beltway 8 , with a radius of approximately 10 miles (16 km) from Downtown, and State Highway 99 (the Grand Parkway), with a radius of 25 miles (40 km). Approximately 470,000 people lived within the Interstate 610 loop, while 1.65 million lived between Interstate 610 and Beltway 8 and 2.25 million lived within Harris County outside Beltway 8 in 2015. Though Houston

18189-487: The wave the more energy it releases and the more sediment it moves. Coastlines with longer shores have more room for the waves to disperse their energy, while coasts with cliffs and short shore faces give little room for the wave energy to be dispersed. In these areas, the wave energy breaking against the cliffs is higher, and air and water are compressed into cracks in the rock, forcing the rock apart, breaking it down. Sediment deposited by waves comes from eroded cliff faces and

18330-476: The wave-front to the shore. These waves which erode the beach are called destructive waves. Low waves that are further apart and break by spilling , expend more of their energy in the swash which carries particles up the beach, leaving less energy for the backwash to transport them downslope, with a net constrictive influence on the beach. Riviera is an Italian word for "shoreline", ultimately derived from Latin ripa ("riverbank"). It came to be applied as

18471-407: The waves surge up the river estuaries from the ocean. Geologists classify coasts on the basis of tidal range into macrotidal coasts with a tidal range greater than 4 m (13 ft); mesotidal coasts with a tidal range of 2 to 4 m (6.6 to 13 ft); and microtidal coasts with a tidal range of less than 2 m (7 ft). The distinction between macrotidal and mesotidal coasts

18612-406: The whole ocean system are ultimately connected, although certain regional classifications are useful and relevant. The waters of the continental shelves represent such a region. The term "coastal waters" has been used in a wide variety of different ways in different contexts. In European Union environmental management it extends from the coast to just a few nautical miles while in the United States

18753-482: The world's people live in coastal regions. According to a United Nations atlas, 44% of all people live within 150 km (93 mi) of the sea. Many major cities are on or near good harbors and have port facilities. Some landlocked places have achieved port status by building canals . Nations defend their coasts against military invaders, smugglers and illegal migrants. Fixed coastal defenses have long been erected in many nations, and coastal countries typically have

18894-481: Was 33.1, up from 32.9 in 2017 and down from 33.5 in 2014; the city's youthfulness has been attributed to an influx of an African American New Great Migration , Hispanic and Latino American, and Asian immigrants into Texas. For every 100 females, there were 98.5 males. There were 987,158 housing units in 2019 and 876,504 households. An estimated 42.3% of Houstonians owned housing units, with an average of 2.65 people per household. The median monthly owner costs with

19035-484: Was 5 °F (−15 °C) on January 18, 1930. The last time Houston saw single digit temperatures was on December 23, 1989. The temperature dropped to 7 °F (−14 °C) at Bush Airport, marking the coldest temperature ever recorded there. 1.7 inches of snow fell at George Bush Intercontinental Airport the previous day. Houston generally receives ample rainfall, averaging about 49.8 in (1,260 mm) annually based on records between 1981 and 2010. Many parts of

19176-441: Was expanded upon by Benoit Mandelbrot . Tides often determine the range over which sediment is deposited or eroded. Areas with high tidal ranges allow waves to reach farther up the shore, and areas with lower tidal ranges produce deposition at a smaller elevation interval. The tidal range is influenced by the size and shape of the coastline. Tides do not typically cause erosion by themselves; however, tidal bores can erode as

19317-446: Was founded by land investors on August 30, 1836, at the confluence of Buffalo Bayou and White Oak Bayou (a point now known as Allen's Landing ) and incorporated as a city on June 5, 1837. The city is named after former General Sam Houston , who was president of the Republic of Texas and had won Texas's independence from Mexico at the Battle of San Jacinto 25 miles (40 km) east of Allen's Landing. After briefly serving as

19458-582: Was founded in 1942 to build ships for the U.S. Navy during World War II. Due to the boom in defense jobs, thousands of new workers migrated to the city, both black, and white people competing for the higher-paying jobs. President Roosevelt had established a policy of nondiscrimination for defense contractors, and black people gained some opportunities, especially in shipbuilding, although not without resistance from white people and increasing social tensions that erupted into occasional violence.
