Seac Pai Van is an area in Macau , located south of the Cotai Strip and on the northeastern parts of Coloane .
41-493: Originally a bay that separated Coloane from Taipa , from the late 2000s it was reclaimed from the sea as a part of the combined island of Cotai , mostly to be turned into public housing. The Land, Public Works and Transport Bureau of Macau announced on September 11, 2009, its plans to build a brand new living area in Seac Pai Van with a population of 60,000, covering an area of about 300,000 square meters. Public housing
82-660: A boom in the firecracker industry in Taipa, especially as colonial officials limited firecracker factories on the Peninsula because of safety concerns following an accident in 1925 that killed 100 people. Many firecracker factories opened, which encouraged people to flock to the island. By 1969, as the Portuguese colonial government sought to improve Macau's infrastructure, a causeway ( Estrada do Istmo ) opened connecting Taipa to Coloane, and in 1974 Taipa got its first connection to
123-550: A combined total of up to 50,000 people. Many government departments have also set up offices in this public housing complex. Seac Pai Van is connected to the rest of Macau by the Cotai Highway. There are 6 bus stops in the area, namely Avenida Butterfly Valley Terminus, Alameda da Harmonia/Edificio Ip Hing, Alameda da Harmonia/Edificio Loc Kuan, Avenida de Loc Koi/Edificio Loc Kuan, Avenida de Loc Koi/Edificio Koi Nga, and Edificio On Son. A Macau LRT connection to this area,
164-462: A regression developed from water samples that are filtered, dried, and weighed), multiplying the concentration with the discharge as above, and integrating over the entire plume. To distinguish the spill contribution, the background turbidity is subtracted from the spill plume turbidity. Since the spill plume in open water varies in space and time, an integration over the entire plume is required, and repeated many times to get acceptably low uncertainty in
205-592: A result of siltation and land reclamation , by the mid-20th century central Taipa had formed, which is largely made up of flat terrain, turning Taipa into one island. Initially, Taipa was connected to Coloane only by the Estrada do Istmo [ zh ] ( 路氹連貫公路 ) causeway, opened in 1969, but starting in the 1990s, land reclamation efforts created a new area, Cotai , and which is home to mega-resorts, casinos, and convention and exhibition centres, and has turned Taipa, Cotai and Coloane all into one island. Taipa
246-555: A tourist destination as its Portuguese architecture attracted tourists and further infrastructure was constructed on the island, including the opening of the Macau International Airport in 1995. In Cantonese , Taipa has been known by many names over time, including 龍環 ( Lung Waan , meaning " Dragon Ring"), 雞頸 ( Gai Geng , "Chicken's neck"), 潭仔 ( Taam Jai , "Pool"), and 龍頭環 ( Lung Tau Waan , "Dragon's-Head Ring"). The Portuguese name "Taipa" comes from
287-506: A wider project by Portugal to turn Macau into a fully-fledged colony and expanding the colony's area to include Taipa, Ilha Verde , Coloane and portions of Hengqin (Montanha). The annexation also aimed to resolve the problem of the divided harbour on the Peninsula and provide land, water supply and protection for the port. Taipa's main industry historically was fishing, with a prominent harbour where fishermen congregated. In 1923, Taipa saw its first firecracker factory open, which encouraged
328-414: Is water pollution caused by particulate terrestrial clastic material, with a particle size dominated by silt or clay . It refers both to the increased concentration of suspended sediments and to the increased accumulation (temporary or permanent) of fine sediments on bottoms where they are undesirable. Siltation is most often caused by soil erosion or sediment spill. It is sometimes referred to by
369-472: Is an area in Macau , connected to Coloane through the area known as Cotai , which is largely built from reclaimed land. Located on the northern half of the island, Taipa's population is mostly suburban. Administratively, the boundaries of the traditional civil parish Freguesia de Nossa Senhora do Carmo are mostly coterminous with that of the former Taipa Island, except for a portion of the parish that lies on
410-684: Is connected to the Macau Peninsula by the Governador Nobre de Carvalho Bridge , Friendship Bridge and the Sai Van Bridge . Taipa is an urbanised, suburban area primarily home to housing, with several housing complexes, which are mostly upscale. As a new town of Macau, Taipa has better city planning than the Macau Peninsula , with wide streets set around a grid system, however Macau has historically centred around
451-513: Is often missing from mobile phone and computer input systems. Another origin of the name, according to local legend, comes from an exchange between early Portuguese settlers on Taipa and the local Chinese. The Portuguese asked the Chinese the name ( nome in Portuguese) of the place. The Chinese settlers were local grocery shopkeepers and spoke no Portuguese, but took the Portuguese nome for

574-531: The Southern Song dynasty . In 1847, encouraged by the governorship of João Maria Ferreira do Amaral , who sought to expand Portugal's influence over Macau and affirm its sovereignty, Lesser Taipa was annexed by the Portuguese, constructing Taipa Fortress upon the command of Pedro Jose da Silva Loureiro to combat marine outlaws and protect Macau against the attack of pirates. By 1851, Portugal had also annexed Greater Taipa. These annexations formed part of
615-475: The offshore dumping of material dredged from harbours and navigation channels. The deposition may also be to build up the coastline, for artificial islands , or for beach replenishment . Climate change also affects siltation rates. Another important cause of siltation is the septage and other sewage sludges that are discharged from households or business establishments with no septic tanks or wastewater treatment facilities to bodies of water. While
656-455: The sediment in transport is in suspension , it acts as a pollutant for those who require clean water, such as for cooling or in industrial processes, and it includes aquatic life that are sensitive to suspended material in the water. While nekton have been found to avoid spill plumes in the water (e.g. the environmental monitoring project during the building of the Øresund Bridge ), filtering benthic organisms have no way of escape. Among
697-464: The Chinese 糯米 , "sticky rice", which is pronounced similar to nome in Cantonese. Thinking the Portuguese settlers were asking if they sold sticky rice, the Chinese responded with " 大把 ", pronounced "daai ba" in Cantonese, meaning "a lot." The Portuguese, hearing the response, took this to be the name of the place. There is, however, no historical evidence to support this story. "Taipa" is also what
738-646: The Chinese pronunciation of 氹仔 in Min Nan / tiap-á / (similar to "tiamp-a") then became "Taipa". The Putonghua pinyin for 氹仔 is dàngzǎi , and this is how the island is referred to in Mandarin. Both the character 氹 and the alternative form 凼 mean cesspit, but are obsolete in modern Chinese, and only used in relation to Taipa and the Macau-Taipa Bridge ( 澳氹大桥 àodàng dàqiáo ). The character 氹 , or 凼 (often used in mainland Chinese texts),
779-485: The Macau Peninsula, the Governador Nobre de Carvalho Bridge, named after the city's governor between 1966 and 1974. Taipa's population, like Coloane, began to expand significantly as better infrastructure was built, increasing from originally 3,000 residents. By the mid-1980s, the firecracker industry in Taipa had declined and the last factory closed in 1984. Starting in the 1990s, Taipa's old village developed as

#1732773255174902-426: The ambiguous term " sediment pollution ", which can also refer to a chemical contamination of sediments accumulated on the bottom, or to pollutants bound to sediment particles. Although "siltation" is not perfectly stringent, since it also includes particle sizes other than silt, it is preferred for its lack of ambiguity. The origin of the increased sediment transport into an area may be erosion on land or activities in
943-734: The area was also served by another public library: the Wong Ieng Kuan Library in Taipa ( Biblioteca de Wong Ieng Kuan da Taipa ; 氹仔黃營均圖書館 ). The library, which opened in January 2005, occupied 1,080 square metres (11,600 sq ft) of space on the second and third floors of Hei Loi Tang Plaza ( 喜來登廣場 ). Its construction was funded with donations from the Wong Ieng Kuan Foundation ( Fundação Wong Ieng Kuan ; 黃營均基金會 ). The Wong Ieng Kuan Library in Taipa closed on 1 January 2022.

Seac Pai Van’s public housing flats are collectively known as the Seac Pai Van Public Housing Complex [ zh ] , which had four public housing projects built as of 2013. Those four public housing projects have names with such meanings as “security”, “housing”, “happiness”, and “business”. They include Edificio On Son, Edificio Koi Nga, Edificio Loc Kuan, and Edificio Ip Hing, all of which can accommodate
1025-429: The first line of defense is to maintain land cover and prevent soil erosion in the first place. The second line of defense is to trap the material before it reaches the stream network (known as sediment control ). In urban areas, the defenses are to keep land uncovered for as short a time as possible during construction and to use silt screens to prevent the sediment from getting released in water bodies. During dredging,
1066-410: The food gathering of filtering organisms, and the sediment accumulation on the bottom may bury organisms to the point that they starve or even die. It is only if the concentration is extreme that it decreases the light level sufficiently for impacting primary productivity. An accumulation of as little as 1 mm (0.039 in) may kill coral polyps. While the effect of the siltation on the biota (once
1107-455: The harm is already done) can be studied by repeated inspection of selected test plots, the magnitude of the siltation process in the impact area may be measured directly by monitoring in real time. Parameters to measure are sediment accumulation, turbidity at the level of the filtering biota, and optionally incident light. Siltation of the magnitude that it affects shipping can also be monitored by repeated bathymetric surveys. In rural areas,
1148-469: The island of Hengqin (Montanha), housing the campus of the University of Macau . Taipa is 2.5 kilometres (1.6 miles) south of the Macau Peninsula and east of the island of Hengqin , which forms a part of the adjacent Chinese city of Zhuhai . The Macau International Airport , University of Macau , Macau Jockey Club and Macau Stadium are all located in Taipa. Taipa's geography is dominated by
1189-476: The most difficult conflicts of interest to resolve, as regards siltation mitigation, is perhaps beach nourishment . When sediments are placed on or near beaches in order to replenish an eroding beach, any fines in the material will continue to be washed out for as long as the sand is being reworked. Since all replenished beaches are eroding or they would not need replenishment, they will contribute to nearshore siltation almost for as long as it takes to erode away what
1230-436: The most sensitive organisms are coral polyps. Generally speaking, hard bottom communities and mussel banks (including oysters) are more sensitive to siltation than sand and mud bottoms. Unlike in the sea, in a stream, the plume will cover the entire channel, except possibly for backwaters, and so fish will also be directly affected in most cases. Siltation can also affect navigation channels or irrigation channels. It refers to
1271-403: The original land-covering vegetation and temporarily creating something akin to an urban desert from which fines are easily washed out during rainstorms. In water, the main pollution source is sediment spill from dredging , the transportation of dredged material on barges, and the deposition of dredged material in or near water. Such deposition may be made to get rid of unwanted material, such as

In 2015 the body of the director general of Macao Customs Service, Lai Minhua , was found in the district. Originally an island pair on the southern end of the Praia Grande , Taipa was first settled by Hokkien -speaking fishermen around 800 years ago. Most Chinese settlement of Taipa occurred during
1353-410: The presence of two hills to the east and west that tower over central Taipa. The 159.1-metre (522.0-foot) Taipa Grande Hill [ zh ] ( 大潭山 , Colina da Taipa Grande ) lies to the east, and Taipa Pequena Hill [ zh ] ( 小潭山 , Colina da Taipa Pequena ) the west. This is because originally Taipa consisted of two islands with a hilly terrain - Greater Taipa and Lesser Taipa. As
1394-474: The proportion of fines in sediments typically increases in the offshore direction, the deposited sand will inevitably contain a significant percentage of siltation-contributing fines. It is desirable to minimize the siltation of irrigation channels by hydrologic design, the objective being not to create zones with falling sediment transport capacity, as that is conducive to sedimentation. Once sedimentation has occurred, in irrigation or navigation channels, dredging
1435-474: The results. The measurements are made close to the source, in the order of a few hundred meters. Anything beyond a work area buffer zone for sediment spill is considered the potential impact area. In the open sea, the impact of concern is almost exclusively with the sessile bottom communities since empirical data show that fish effectively avoid the impacted area. The siltation affects the bottom community in two main ways. The suspended sediment may interfere with
1476-409: The spill can be minimized but not eliminated completely by the way the dredger is designed and operated. If the material is deposited on land, efficient sedimentation basins can be constructed. If it is dumped into relatively deep water, there will be a significant spill during dumping but not thereafter, and the spill that arises has minimal impact if there are only fine-sediment bottoms nearby. One of

Also, sediment spill is better measured in transport than at the source. The sediment transport in open water is estimated by measuring the turbidity , correlating turbidity to sediment concentration (using
1558-409: The undesired accumulation of sediments in channels intended for vessels or for distributing water. One may distinguish between measurements at the source, during transport, and within the affected area. Source measurements of erosion may be very difficult since the lost material may be a fraction of a millimeter per year. Therefore, the approach taken is typically to measure the sediment in transport in
1599-400: The water. In rural areas, the erosion source is typically soil degradation by intensive or inadequate agricultural practices, leading to soil erosion , especially in fine-grained soils such as loess . The result will be an increased amount of silt and clay in the water bodies that drain the area. In urban areas, the erosion source is typically construction activities, which involve clearing

Since the leakage is detrimental to coral reefs, the practice leads to a direct conflict between the public interest of saving beaches, and preserving any nearshore coral reefs. To minimize the conflict, beach replenishment should not be done with sand containing any silt or clay fractions. In practice the sand is often taken from offshore areas, and since

In order to maintain the positioning of Coloane as the lung of Macau, the area would be heavily greened near the Luen Seng Industrial Estate and adjacent quarry, both of which were originally lacking in greenery, so as to harmonize the area with the scenery of the adjacent Seac Pai Van Park . In line with the government's environmental policies, natural gas was also to be introduced to
