84-577: The river is named for the Miami , an Algonquian -speaking Native American people who lived in the region during the early days of European settlement. They were forced to relocate to the west to escape pressure from European-American settlers. The region surrounding the Great Miami River is known as the Miami Valley . This term is used in the upper portions of the valley as a moniker for

168-449: A dam , landslide, or glacier . In one instance, a flash flood killed eight people enjoying the water on a Sunday afternoon at a popular waterfall in a narrow canyon. Without any observed rainfall, the flow rate increased from about 50 to 1,500 cubic feet per second (1.4 to 42 m /s) in just one minute. Two larger floods occurred at the same site within a week, but no one was at the waterfall on those days. The deadly flood resulted from

252-646: A flash flood . Flash floods usually result from intense rainfall over a relatively small area, or if the area was already saturated from previous precipitation. The amount, location, and timing of water reaching a drainage channel from natural precipitation and controlled or uncontrolled reservoir releases determines the flow at downstream locations. Some precipitation evaporates, some slowly percolates through soil, some may be temporarily sequestered as snow or ice, and some may produce rapid runoff from surfaces including rock, pavement, roofs, and saturated or frozen ground. The fraction of incident precipitation promptly reaching

336-515: A landslide , earthquake or volcanic eruption . Examples include outburst floods and lahars . Tsunamis can cause catastrophic coastal flooding , most commonly resulting from undersea earthquakes. The primary effects of flooding include loss of life and damage to buildings and other structures, including bridges, sewerage systems, roadways, and canals. The economic impacts caused by flooding can be severe. Every year flooding causes countries billions of dollars worth of damage that threatens

420-484: A tropical cyclone or an extratropical cyclone , falls within this category. A storm surge is "an additional rise of water generated by a storm, over and above the predicted astronomical tides". Due to the effects of climate change (e.g. sea level rise and an increase in extreme weather events) and an increase in the population living in coastal areas, the damage caused by coastal flood events has intensified and more people are being affected. Flooding in estuaries

504-538: A bitter schism. Those who affiliated with the tribe were moved to first to Kansas , then to Oklahoma , where they were given individual allotments of land rather than a reservation as part of efforts to make them assimilate into the American culture of private property and yeoman farming. The U.S. government has recognized what is now the Miami Tribe of Oklahoma as the official tribal government since 1846. In

588-581: A coalition of Native American nations. Territorial governor William Henry Harrison and his forces destroyed Prophetstown in 1811, and in the War of 1812 – which included a tribal siege of Fort Wayne – attacked Miami villages throughout the Indiana Territory. Although Wayne had promised in the Treaty of Greenville negotiations that the remaining unceded territory would remain tribal land – the origin of

672-468: A country can be lost in extreme flood circumstances. Some tree species may not survive prolonged flooding of their root systems. Flooding in areas where people live also has significant economic implications for affected neighborhoods. In the United States , industry experts estimate that wet basements can lower property values by 10–25 percent and are cited among the top reasons for not purchasing

756-538: A drainage channel has been observed from nil for light rain on dry, level ground to as high as 170 percent for warm rain on accumulated snow. Most precipitation records are based on a measured depth of water received within a fixed time interval. Frequency of a precipitation threshold of interest may be determined from the number of measurements exceeding that threshold value within the total time period for which observations are available. Individual data points are converted to intensity by dividing each measured depth by

840-627: A few minutes for roof and parking lot drainage structures, while cumulative rainfall over several days would be critical for river basins. Water flowing downhill ultimately encounters downstream conditions slowing movement. The final limitation in coastal flooding lands is often the ocean or some coastal flooding bars which form natural lakes . In flooding low lands, elevation changes such as tidal fluctuations are significant determinants of coastal and estuarine flooding. Less predictable events like tsunamis and storm surges may also cause elevation changes in large bodies of water. Elevation of flowing water

924-605: A few. Gastrointestinal disease and diarrheal diseases are very common due to a lack of clean water during a flood. Most of clean water supplies are contaminated when flooding occurs. Hepatitis A and E are common because of the lack of sanitation in the water and in living quarters depending on where the flood is and how prepared the community is for a flood. When floods hit, people lose nearly all their crops, livestock, and food reserves and face starvation. Floods also frequently damage power transmission and sometimes power generation , which then has knock-on effects caused by

1008-728: A home. According to the U.S. Federal Emergency Management Agency (FEMA), almost 40 percent of small businesses never reopen their doors following a flooding disaster. In the United States, insurance is available against flood damage to both homes and businesses. Economic hardship due to a temporary decline in tourism, rebuilding costs, or food shortages leading to price increases is a common after-effect of severe flooding. The impact on those affected may cause psychological damage to those affected, in particular where deaths, serious injuries and loss of property occur. Fatalities connected directly to floods are usually caused by drowning ;

1092-486: A more distant point controls at higher water levels. Effective flood channel geometry may be changed by growth of vegetation, accumulation of ice or debris, or construction of bridges, buildings, or levees within the flood channel. Periodic floods occur on many rivers, forming a surrounding region known as the flood plain . Even when rainfall is relatively light, the shorelines of lakes and bays can be flooded by severe winds—such as during hurricanes —that blow water into

1176-623: A policy of leveraging these debts to induce tribal leaders to sign new treaties ceding large swaths of collectively-held reservation land and then to agree to the tribe's removal. As incentives to induce tribal leaders to sign such treaties, the government gave them individual deeds and other personal perks, such as building one chief a mansion . In 1846, the government forced the tribe's rank-and-file to leave, but several major families who had acquired private property to live on through this practice were exempted and permitted to stay in Indiana, creating

1260-602: A subset of the so-called Western Confederacy during the Northwest Indian War. The U.S. government later included the Miami with the Illini for administrative purposes. The Eel River band maintained a somewhat separate status, which proved beneficial in the removals of the 19th century. The Miami nation's traditional capital was Kekionga . French years British years The Miami had mixed relations with

1344-413: A thunderstorm over part of the drainage basin, where steep, bare rock slopes are common and the thin soil was already saturated. Flash floods are the most common flood type in normally-dry channels in arid zones, known as arroyos in the southwest United States and many other names elsewhere. In that setting, the first flood water to arrive is depleted as it wets the sandy stream bed. The leading edge of

1428-520: A type of hybrid river/areal flooding can occur, known locally as "overland flooding". This is different from "overland flow" defined as "surface runoff". The Red River Valley is a former glacial lakebed, created by Lake Agassiz , and over a length of 550 mi (890 km), the river course drops only 236 ft (72 m), for an average slope of about 5 inches per mile (or 8.2 cm per kilometer). In this very large area, spring snowmelt happens at different rates in different places, and if winter snowfall

1512-405: Is also the intentional flooding of land that would otherwise remain dry. This may take place for agricultural, military, or river-management purposes. For example, agricultural flooding may occur in preparing paddy fields for the growing of semi-aquatic rice in many countries. Flooding may occur as an overflow of water from water bodies, such as a river , lake , sea or ocean. In these cases,

1596-419: Is common when heavy flows move uprooted woody vegetation and flood-damaged structures and vehicles, including boats and railway equipment. Recent field measurements during the 2010–11 Queensland floods showed that any criterion solely based upon the flow velocity, water depth or specific momentum cannot account for the hazards caused by velocity and water depth fluctuations. These considerations ignore further

1680-493: Is commonly caused by a combination of storm surges caused by winds and low barometric pressure and large waves meeting high upstream river flows. The intentional flooding of land that would otherwise remain dry may take place for agricultural, military or river-management purposes. This is a form of hydraulic engineering . Agricultural flooding may occur in preparing paddy fields for the growing of semi-aquatic rice in many countries. Flooding for river management may occur in

1764-400: Is controlled by the geometry of the flow channel and, especially, by depth of channel, speed of flow and amount of sediments in it Flow channel restrictions like bridges and canyons tend to control water elevation above the restriction. The actual control point for any given reach of the drainage may change with changing water elevation, so a closer point may control for lower water levels until

1848-759: Is joined by the Stillwater and the Mad rivers and Wolf Creek . From Dayton it flows southwest past Miamisburg , Franklin , Middletown and Hamilton in the southwest corner of Ohio. In southwestern Hamilton County , it is joined by the Whitewater River approximately 5 miles (8.0 km) upstream from its mouth on the Ohio River , just east of the Ohio - Indiana state line, approximately 16 miles (26 km) west of Cincinnati . The river meanders across

1932-461: Is more significant to flooding within small drainage basins. The most important upslope factor in determining flood magnitude is the land area of the watershed upstream of the area of interest. Rainfall intensity is the second most important factor for watersheds of less than approximately 30 square miles or 80 square kilometres. The main channel slope is the second most important factor for larger watersheds. Channel slope and rainfall intensity become

2016-598: Is now Wisconsin , from which they migrated south and eastwards from the mid-17th century to the mid-18th century, settling on the upper Wabash River and the Maumee River in what is now northeastern Indiana and northwestern Ohio. By oral history, this migration was a return to the region where they had long lived before being invaded during the Beaver Wars by the Iroquois . Early European colonists and traders on

2100-599: Is now Kansas, and later to what is now part of Oklahoma ). The Miami Tribe of Oklahoma are the federally recognized tribe of Miami Indians in the United States. The Miami Nation of Indiana , a nonprofit organization of self-identified descendants of Miamis who were exempted from removal, have unsuccessfully sought separate recognition. The name Miami derives from '(plural Myaamiaki ), the tribe's autonym (name for themselves) in their Algonquian language of Miami–Illinois . This appears to have been derived from an older term meaning "downstream people." Some scholars contended

2184-658: The Great Lakes tribes, they occupied territory that is now identified as north-central Indiana , southwest Michigan , and western Ohio . The Miami were historically made up of several prominent subgroups, including the Piankeshaw , Wea , Pepikokia, Kilatika, Mengakonkia, and Atchakangouen. In modern times, Miami is used more specifically to refer to the Atchakangouen. By 1846, most of the Miami had been forcefully displaced to Indian Territory (initially to what

2268-553: The Miami Conservancy District was established in 1914 to build dams , levees and storage areas as well as dredge and straighten channels to control flooding of the river. The Great Miami River has also been known as: Miami tribe The Miami ( Miami–Illinois : Myaamiaki ) are a Native American nation originally speaking one of the Algonquian languages . Among the peoples known as

2352-629: The Miami Tribe of Oklahoma changed its constitution to permit any descendant of people on certain historical roles to join, and since then hundreds of Indiana-based Miami have become members. Today the Oklahoma-based Miami tribe has about 5,600 enrolled members. However many other Indiana-based Miami still consider themselves a separate group that has been unfairly denied separate federal recognition. The Miami Nation of Indiana does not have federal tribal recognition. Senate Bill No. 311

2436-562: The Second World War ). Floods are caused by many factors or a combination of any of these generally prolonged heavy rainfall (locally concentrated or throughout a catchment area), highly accelerated snowmelt , severe winds over water, unusual high tides, tsunamis , or failure of dams, levees , retention ponds , or other structures that retained the water. Flooding can be exacerbated by increased amounts of impervious surface or by other natural hazards such as wildfires, which reduce

2520-483: The Treaty of Greenville in 1795, which ended the Northwest Indian War. Under it, confederacy leaders like Little Turtle agreed to cede most of what is now Ohio, along with other tracts to the west including what is now central Detroit, Chicago, and Fort Wayne, in exchange for annual payments. Those Miami who still resented the United States gathered around Ouiatenon and Prophetstown , where Shawnee Chief Tecumseh led

2604-562: The water table is shallow, such as a floodplain , or from intense rain from one or a series of storms . Infiltration also is slow to negligible through frozen ground, rock, concrete , paving, or roofs. Areal flooding begins in flat areas like floodplains and in local depressions not connected to a stream channel, because the velocity of overland flow depends on the surface slope. Endorheic basins may experience areal flooding during periods when precipitation exceeds evaporation. Floods occur in all types of river and stream channels, from

2688-545: The 17th and 18th centuries, the term "Miami" generally referred to all of these bands as one grand tribe. Over the course of the 19th century, "Miami" came to specifically refer to the Atchakangoen (Crane) band. Around the beginning of the 18th century, with support from French traders coming down from what is now Canada who supplied them with firearms and wanted to trade with them for furs, the Miami pushed back into their historical territory and resettled it. At this time,

2772-579: The 20th century, the Indiana-based Miami unsuccessfully sought separate federal recognition. Although they had been recognized by the U.S. in an 1854 treaty, that recognition was stripped in 1897. In 1980, the Indiana legislature recognized the Eastern Miami as a matter of state law and voted to support federal recognition, but in 1993, a federal judge ruled that the statute of limitations on appealing their status had expired. In 1996,

2856-681: The East Coast had fueled demand for furs, and the Iroquois – based in central and western New York – had acquired early access to European firearms through trade and had used them to conquer the Ohio Valley area for use as hunting grounds, which temporarily depopulated as Algonquin woodlands tribes fled west as refugees. The warfare and ensuing social disruption – along with the spread of infectious European diseases such as measles and smallpox for which they had no immunity – contributed to

2940-496: The Fisher Tradition of Mississippian culture . Mississippian societies were characterized by maize -based agriculture, chiefdom -level social organization, extensive regional trade networks, hierarchical settlement patterns, and other factors. The historical Miami engaged in hunting, as did other Mississippian peoples. Written history of the Miami traces back to missionaries and explorers who encountered them in what

3024-536: The George Washington administration ordered an attack on Kekionga in 1790; American forces destroyed it but were then repulsed by Little Turtle's warriors . In 1791, Lieutenant Colonel James Wilkinson launched what he thought was a clever raid. At the Battle of Kenapacomaqua , Wilkinson killed 9 Wea and Miami, and captured 34 Miami as prisoners, including a daughter of Miami war chief Little Turtle. Many of

3108-538: The Great Miami fed into the canal. A later extension to the canal, the Sidney Feeder, drew water from the upper reaches of the Great Miami from near Port Jefferson and Sidney . The canal served as the principal north–south route of transportation from Toledo to Cincinnati for western Ohio until being supplanted in the 1850s by railroads. As was common in early industrial days, beginning in the 19th century

3192-840: The Maumee River (which flowed into Lake Erie and offered a water path to Quebec) to the Wabash River (which flowed into the Ohio River and offered a water path to the Mississippi Valley). By the 18th century, the Miami had for the most part returned to their homeland in present-day Indiana and Ohio. The eventual victory of the British in the French and Indian War ( Seven Years' War ) led to an increased British presence in traditional Miami areas. Shifting alliances and

3276-726: The Miami called themselves the Twightwee (also spelled Twatwa ), supposedly an onomatopoeic reference to their sacred bird, the sandhill crane . Recent studies have shown that Twightwee derives from the Delaware language exonym for the Miamis, tuwéhtuwe , a name of unknown etymology. Some Miami have stated that this was only a name used by other tribes for the Miami, and not their autonym. They also called themselves Mihtohseeniaki (the people). The Miami continue to use this autonym today. Early Miami people are considered to belong to

3360-550: The Northwest Territory – modern-day Ohio, Indiana, Illinois, Michigan, and Wisconsin – to the new United States. White pioneers pushed into the Ohio Valley, leading to disputes over whether they had a legal right to carve out homesteads and settlements on land the tribes considered unceded territory. The Miami invited tribes displaced by white settlers, the Delaware (Lenape) and Shawnee to resettle at Kekionga, forming

3444-742: The United States. Some villages of the Piankeshaw openly supported the American rebel colonists during the American Revolution , while the villages around Ouiatenon were openly hostile. The Miami of Kekionga remained allies of the British, but were not openly hostile to the United States (except when attacked by Augustin de La Balme in 1780). In the 1783 Treaty of Paris, which ended the American Revolutionary War , Britain transferred its claim of sovereignty over

3528-717: The adverse ecological impact of the inundation. That impact may also be adverse in a hydrogeological sense if the inundation lasts a long time. Examples for uncontrolled inundations are the second Siege of Leiden during the first part of the Eighty Years' War , the flooding of the Yser plain during the First World War , and the Inundation of Walcheren , and the Inundation of the Wieringermeer during

3612-423: The amount of water damage and mold that grows after an incident. Research suggests that there will be an increase of 30–50% in adverse respiratory health outcomes caused by dampness and mold exposure for those living in coastal and wetland areas. Fungal contamination in homes is associated with increased allergic rhinitis and asthma. Vector borne diseases increase as well due to the increase in still water after

3696-462: The confederation leaders had been considering terms of peace to present to the United States, but when they received news of Wilkinson's raid, they readied for war. Wilkinson's raid thus had the opposite effect and united the tribes for a war. Later in 1791, the Washington administration organized a second expedition to attack Kekionga with further orders to build a fort there to permanently occupy

3780-434: The deadliest floods worldwide, showing events with death tolls at or above 100,000 individuals. Floods (in particular more frequent or smaller floods) can also bring many benefits, such as recharging ground water , making soil more fertile and increasing nutrients in some soils. Flood waters provide much needed water resources in arid and semi-arid regions where precipitation can be very unevenly distributed throughout

3864-400: The decimation of Native American populations in the interior. Historic locations When French missionaries first encountered the Miami in the mid-17th century, generating the first written historical record of the tribe, the indigenous people were living around the western shores of Lake Michigan . According to Miami oral tradition, they had moved there a few generations earlier from

3948-658: The economic-cultural region centered primarily on the Greater Dayton area. As the lower portions of the Miami Valley fall under the influence of Cincinnati and the Ohio River Valley, residents of the lower area do not identify with the Miami in the same way. The main course of the Great Miami River rises from the outflow of Indian Lake in Logan County , about 1 mile (1.6 km) southeast of

4032-576: The field that is intended to impede the movement of the enemy. This may be done both for offensive and defensive purposes. Furthermore, in so far as the methods used are a form of hydraulic engineering, it may be useful to differentiate between controlled inundations and uncontrolled ones. Examples for controlled inundations include those in the Netherlands under the Dutch Republic and its successor states in that area and exemplified in

4116-470: The flood process; before, during and after. During floods accidents occur with falling debris or any of the many fast moving objects in the water. After the flood rescue attempts are where large numbers injuries can occur. Communicable diseases are increased due to many pathogens and bacteria that are being transported by the water .There are many waterborne diseases such as cholera , hepatitis A , hepatitis E and diarrheal diseases , to mention

4200-492: The flood thus advances more slowly than later and higher flows. As a result, the rising limb of the hydrograph becomes ever quicker as the flood moves downstream, until the flow rate is so great that the depletion by wetting soil becomes insignificant. Coastal areas may be flooded by storm surges combining with high tides and large wave events at sea, resulting in waves over-topping flood defenses or in severe cases by tsunami or tropical cyclones. A storm surge , from either

4284-403: The floods have settled. The diseases that are vector borne are malaria , dengue , West Nile , and yellow fever . Floods have a huge impact on victims' psychosocial integrity . People suffer from a wide variety of losses and stress . One of the most treated illness in long-term health problems are depression caused by the flood and all the tragedy that flows with one. Below is a list of

SECTION 50

#1732765337392

4368-428: The flow rate exceeds the capacity of the river channel , particularly at bends or meanders in the waterway . Floods often cause damage to homes and businesses if these buildings are in the natural flood plains of rivers. People could avoid riverine flood damage by moving away from rivers. However, people in many countries have traditionally lived and worked by rivers because the land is usually flat and fertile . Also,

4452-656: The form of diverting flood waters in a river at flood stage upstream from areas that are considered more valuable than the areas that are sacrificed in this way. This may be done ad hoc , or permanently, as in the so-called overlaten (literally "let-overs"), an intentionally lowered segment in Dutch riparian levees, like the Beerse Overlaat in the left levee of the Meuse between the villages of Gassel and Linden, North Brabant . Military inundation creates an obstacle in

4536-537: The gradual encroachment of European-American settlement led to some Miami bands, including the Piankeshaw , and Wea , effectively merging into what was sometimes called the Miami Confederacy. Native Americans created larger tribal confederacies led by Chief Little Turtle ; their alliances were for waging war against Europeans and to fight advancing white settlement, and the broader Miami itself became

4620-403: The land in quantities that cannot be carried within stream channels or retained in natural ponds, lakes, and human-made reservoirs . About 30 percent of all precipitation becomes runoff and that amount might be increased by water from melting snow. River flooding is often caused by heavy rain, sometimes increased by melting snow. A flood that rises rapidly, with little or no warning, is called

4704-614: The livelihood of individuals. As a result, there is also significant socio-economic threats to vulnerable populations around the world from flooding. For example, in Bangladesh in 2007, a flood was responsible for the destruction of more than one million houses. And yearly in the United States, floods cause over $ 7 billion in damage. Flood waters typically inundate farm land, making the land unworkable and preventing crops from being planted or harvested, which can lead to shortages of food both for humans and farm animals. Entire harvests for

4788-417: The location of the flood. Damage to roads and transport infrastructure may make it difficult to mobilize aid to those affected or to provide emergency health treatment. Flooding can cause chronically wet houses, leading to the growth of indoor mold and resulting in adverse health effects, particularly respiratory symptoms. Respiratory diseases are a common after the disaster has occurred. This depends on

4872-436: The loss of power. This includes loss of drinking water treatment and water supply, which may result in loss of drinking water or severe water contamination. It may also cause the loss of sewage disposal facilities. Lack of clean water combined with human sewage in the flood waters raises the risk of waterborne diseases , which can include typhoid , giardia , cryptosporidium , cholera and many other diseases depending upon

4956-613: The major bands of the Miami were: In 1696, the Comte de Frontenac appointed Jean Baptiste Bissot, Sieur de Vincennes as commander of the French outposts in northeast Indiana and southwest Michigan. He befriended the Miami people, settling first at the St. Joseph River , and, in 1704, establishing a trading post and fort at Kekionga , present-day Fort Wayne, Indiana , the de facto Miami capital which controlled an important land portage linking

5040-466: The name "Indiana" – forever, that is not what happened. Wayne would die a year later. White traders who came to Fort Wayne were used by the government to deliver the annual treaty payments to the Miami and other tribes. The traders also sold them alcohol and manufactured goods. Between annuity days, the traders sold them such things on credit, and the tribes repeatedly ran up more debts than the existing payments could cover. Harrison and his successors pursued

5124-507: The nucleus of the pan-tribal Western Confederacy. War parties attacked white settlers, seeking to drive them out, and whites – including Kentucky militia members – carried out sometimes indiscriminate reprisal attacks on Native American villages. The resulting conflict became known as the Northwest Indian War . Seeking to bring an end to the rising violence by forcing the tribes to sign treaties ceding land for white settlement,

5208-457: The period of time between observations. This intensity will be less than the actual peak intensity if the duration of the rainfall event was less than the fixed time interval for which measurements are reported. Convective precipitation events (thunderstorms) tend to produce shorter duration storm events than orographic precipitation. Duration, intensity, and frequency of rainfall events are important to flood prediction. Short duration precipitation

5292-471: The region that is now northern Indiana, southern Michigan, and northwestern Ohio to escape pressure from Iroquois war parties seeking to monopolize control over furs in the Ohio Valley. Early French explorers noticed many linguistic and cultural similarities between the Miami bands and the Illiniwek , a loose confederacy of Algonquian-speaking peoples. The term "Miami" has imprecise meaning to historians. In

5376-544: The region, but the Western Confederacy attacked its camp en route and destroyed it; the battle, known as St. Clair's Defeat , is recognized as the worst defeat of an American army by Native Americans in U.S. history. In 1794, a third invading force under General "Mad" Anthony Wayne defeated the confederacy at the Battle of Fallen Timbers , burned tribal settlements along dozens of miles of the Maumee River, and erected Fort Wayne at Kekionga. Wayne then imposed

5460-586: The result of sustained rainfall, rapid snow melt, monsoons , or tropical cyclones . However, large rivers may have rapid flooding events in areas with dry climates, since they may have large basins but small river channels, and rainfall can be very intense in smaller areas of those basins. In extremely flat areas, such as the Red River Valley of the North in Minnesota , North Dakota , and Manitoba ,

5544-480: The risks associated with large debris entrained by the flow motion. Floods can be a huge destructive power. When water flows, it has the ability to demolish all kinds of buildings and objects, such as bridges, structures, houses, trees, and cars. Economical, social and natural environmental damages are common factors that are impacted by flooding events and the impacts that flooding has on these areas can be catastrophic. There have been numerous flood incidents around

5628-456: The river served as a source of water and a method to dispose of wastes for a variety of major industrial firms, including Armco Steel , Champion International Paper , Black Clawson , Fernald and many others. Heightened attention to water pollution in the late 1950s and 1960s has led to significant improvements in waste disposal and water quality. Following a catastrophic flood in March 1913,

5712-454: The rivers provide easy travel and access to commerce and industry. Flooding can damage property and also lead to secondary impacts. These include in the short term an increased spread of waterborne diseases and vector-bourne disesases , for example those diseases transmitted by mosquitos. Flooding can also lead to long-term displacement of residents. Floods are an area of study of hydrology and hydraulic engineering . A large amount of

5796-497: The shore areas. Extreme flood events often result from coincidence such as unusually intense, warm rainfall melting heavy snow pack, producing channel obstructions from floating ice, and releasing small impoundments like beaver dams. Coincident events may cause extensive flooding to be more frequent than anticipated from simplistic statistical prediction models considering only precipitation runoff flowing within unobstructed drainage channels. Debris modification of channel geometry

5880-538: The smallest ephemeral streams in humid zones to normally-dry channels in arid climates to the world's largest rivers. When overland flow occurs on tilled fields, it can result in a muddy flood where sediments are picked up by run off and carried as suspended matter or bed load . Localized flooding may be caused or exacerbated by drainage obstructions such as landslides , ice , debris , or beaver dams. Slow-rising floods most commonly occur in large rivers with large catchment areas . The increase in flow may be

5964-502: The state line near Lawrenceburg, Indiana in the last two miles (3 km) before reaching its mouth approximately ¼ mile east of the border in Ohio. The border of Ohio and Indiana was based on where the confluence of the Ohio and Great Miami Rivers was in 1800. Download coordinates as: In the 1700s, the French called the river Riviere à la Roche ("River of the Rocks"). This name

6048-527: The supply of vegetation that can absorb rainfall. During times of rain, some of the water is retained in ponds or soil, some is absorbed by grass and vegetation, some evaporates, and the rest travels over the land as surface runoff . Floods occur when ponds, lakes, riverbeds, soil, and vegetation cannot absorb all the water. This has been exacerbated by human activities such as draining wetlands that naturally store large amounts of water and building paved surfaces that do not absorb any water. Water then runs off

6132-440: The third most important factors for small and large watersheds, respectively. Time of Concentration is the time required for runoff from the most distant point of the upstream drainage area to reach the point of the drainage channel controlling flooding of the area of interest. The time of concentration defines the critical duration of peak rainfall for the area of interest. The critical duration of intense rainfall might be only

6216-699: The two Hollandic Water Lines , the Stelling van Amsterdam , the Frisian Water Line , the IJssel Line , the Peel-Raam Line , and the Grebbe line in that country. To count as controlled , a military inundation has to take the interests of the civilian population into account, by allowing them a timely evacuation , by making the inundation reversible , and by making an attempt to minimize

6300-730: The unrelated Mayaimi people. Flood A flood is an overflow of water ( or rarely other fluids ) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide . Floods are of significant concern in agriculture , civil engineering and public health . Human changes to the environment often increase the intensity and frequency of flooding. Examples for human changes are land use changes such as deforestation and removal of wetlands , changes in waterway course or flood controls such as with levees . Global environmental issues also influence causes of floods, namely climate change which causes an intensification of

6384-528: The village of Russells Point , approximately 15 miles (24 km) southeast of Lima . Indian Lake is an artificial reservoir which receives the flow from the North and South forks of the Great Miami River. It flows south and southwest, past Sidney , and is joined by Loramie Creek in northern Miami County . It flows south past Piqua and Troy , and through Taylorsville Dam in Huber Heights and Vandalia . It continues through Dayton , where it

6468-441: The water cycle and sea level rise . For example, climate change makes extreme weather events more frequent and stronger. This leads to more intense floods and increased flood risk. Natural types of floods include river flooding, groundwater flooding coastal flooding and urban flooding sometimes known as flash flooding. Tidal flooding may include elements of both river and coastal flooding processes in estuary areas. There

6552-487: The water overtops or breaks levees , resulting in some of that water escaping its usual boundaries. Flooding may also occur due to an accumulation of rainwater on saturated ground. This is called an areal flood . The size of a lake or other body of water naturally varies with seasonal changes in precipitation and snow melt. Those changes in size are however not considered a flood unless they flood property or drown domestic animals . Floods can also occur in rivers when

6636-515: The waters in a flood are very deep and have strong currents . Deaths do not just occur from drowning, deaths are connected with dehydration , heat stroke , heart attack and any other illness that needs medical supplies that cannot be delivered. Injuries can lead to an excessive amount of morbidity when a flood occurs. Injuries are not isolated to just those who were directly in the flood, rescue teams and even people delivering supplies can sustain an injury. Injuries can occur anytime during

6720-450: The world which have caused devastating damage to infrastructure, the natural environment and human life. Floods can have devastating impacts to human societies. Flooding events worldwide are increasing in frequency and severity, leading to increasing costs to societies. Catastrophic riverine flooding can result from major infrastructure failures, often the collapse of a dam . It can also be caused by drainage channel modification from

6804-557: The world's population lives in close proximity to major coastlines , while many major cities and agricultural areas are located near floodplains . There is significant risk for increased coastal and fluvial flooding due to changing climatic conditions. Floods can happen on flat or low-lying areas when water is supplied by rainfall or snowmelt more rapidly than it can either infiltrate or run off . The excess accumulates in place, sometimes to hazardous depths. Surface soil can become saturated, which effectively stops infiltration, where

6888-528: Was directly taken from the Myaamia language (Miami-Illinois) of the Miami Nation that lived in the area ( ahseni siipiiwi , meaning Rock River ). The Miami and Erie Canal , which connected the Ohio River with Lake Erie , was built through the Great Miami watershed. The first portion of the canal, from Cincinnati to Middletown , was operational in 1828, and extended to Dayton in 1830. Water from

6972-765: Was heavy, a fast snowmelt can push water out of the banks of a tributary river so that it moves overland, to a point further downstream in the river or completely to another streambed. Overland flooding can be devastating because it is unpredictable, it can occur very suddenly with surprising speed, and in such flat land it can run for miles. It is these qualities that set it apart from simple "overland flow". Rapid flooding events, including flash floods , more often occur on smaller rivers, rivers with steep valleys, rivers that flow for much of their length over impermeable terrain, or normally-dry channels. The cause may be localized convective precipitation (intense thunderstorms ) or sudden release from an upstream impoundment created behind

7056-606: Was introduced in the Indiana General Assembly in 2011 to formally grant state recognition to the tribe, giving it sole authority to determine its tribal membership, but the bill did not advance to a vote. United States years A number of places have been named for the Miami nation. However, Miami, Florida is not named for this tribe, but for the Miami River in Florida, which is in turn named after
