The central lowlands extend into Vietnam to the south-east. Below Myanmar, the river basin may be divided into six major sections on the basis of landforms, vegetation, and soils: the northern highlands, Khorat Plateau, eastern highlands, southern lowlands, southern highlands, and delta. Articles from Britannica Encyclopedias for elementary and high school students. The Mekong River flows in from the northeast and the Tonle Sap river emanates from the Tonle Sap—flows in from the northwest. Rio de Janeiro ("River of January" in Portuguese) Famous City in southeastern Brazil and former capital of the country from 1764 to 1960. If you were traveling in Sichuan, what country would you be in? This is partly because of the region’s location — it is an isolated, inaccessible place — and because decades of war and conflict perversely protected the forests from over-exploitation. The Mekong’s most important tributaries in this region are the Kading, the Bangfai, the Banghiang, and the Kong—which, with its affluent the San, drains a large area of southern Laos, central Vietnam, and eastern Cambodia. The southwest monsoon brings the rainy season from mid-May to mid-September or to early October, and the northeast monsoon flow of drier and cooler air lasts from early November to March. [39][59], Cambodia’s islands fall under administration of the 4 coastal provinces. International Tropical Timber Agreement, 1994", "KRAM DATED OCTOBER 22, 1996 ON THE ADOPTION OF THE CONVENTION ON WETLANDS OF INTERNATIONAL IMPORTANCE - ESPECIALLY AS WATERFOWL HABITAT", "LAW OF THE SEA 6 . In its upper reaches, the Mekong rises in the Tibetan Plateau between the Salween and Yangtze rivers; the streambed has cut deeply into the rugged landscape through which it flows.

Rising in southeastern Qinghai province, China, it flows through the eastern part of the Tibet Autonomous Region and Yunnan province, after which it forms part of the international border between Myanmar (Burma) and Laos, as well as between Laos and Thailand. The Mekong River flows southward from the Cambodia-Laos border to a point south of Kratié (town), where it turns west for about 50 km (31 mi) and then turns southwest towards Phnom Penh. The trees offer refuge and nursery grounds for fish, crabs, shrimp, and mollusks. They also provide homes for monkeys, lizards, sea turtles, and many other animals as well as countless insects. From Kampong Cham Province the gradient slopes very gently, and inundation of areas along the river occurs at flood stage. The sediment deposited into the lake during the Mekong's flood stage appears to be greater than the quantity carried away later by the Tonle Sap River. Its waters' flow reverses direction every year, caused by greatly varying amounts of water carried by the Mekong over the course of a year and the impact of monsoonal rains, that coincides with the river's maximum. Several streams flow from these uplands into the Tonle Sap. [31], "Sandy materials cover a large proportion of the landscape of Cambodia, on account of the siliceous sedimentary formations that underlie much of the Kingdom. The complex geological, topographic and climatic ( rainfall and temperature ) facets that characterize the region make forest structure and composition unique and very variable. As of 2009 there were more than 400 bridges in Venice, Italy. Low fertility and toxic amounts of aluminium pose limitations to its agricultural use, crops that can be successfully cultivated include rubber tree, oil palm, coffee and sugar cane.

Cruise Reviews More than 1500 real cruise line & ship reviews Opinions on service, food, entertainment & cabins View all opinions here! The freshwater wetlands of Cambodia represent one of the most diverse ecosystems worldwide. "There is extreme hydrodynamic complexity in both time and space and it becomes impossible to measure channel discharge. However, concerns that the lake is rapidly filling with sediment seem - according to studies[97] - to be unfounded at the present time. The river divides into two branches below Phnom Penh: the Mekong proper and the Bassac (Basak). Soils and deciduous vegetation on the hills are thin, and much of the original forest has been replaced by grassland as a result of grazing and repeated burning. The 541 km (336 mi) border with Laos and the 1,228 km (763 mi) border with Vietnam result from French administrative decisions and do not follow major natural features. "[33], The vast alluvial and lacustrine interconnected Cambodian flood-plain is a geologically relatively recent depression where the sediments of the Mekong and its tributaries accumulate as waters are subject to frequent course changes. The Songkhram River drains the northern part of the plateau and enters the Mekong above Tha Uthen in Thailand. territorial sea: Our guide Mr. Peter was very noligable about firstly the city, history, and when we boarded the train, explained how it came about.Made 2 stops along the way, viewing a large fruit and vegetable market, and to change trains.The sites of Yangon is definitely something to see, that I highly recommend it to anyone visiting Yangon. Cambodia has 2 main sources of natural freshwater, the Mekong River and the Tonle Sap, a huge lake connected to the Mekong. Plants and animals adapted to moist conditions, to seek refuge here and evolve into highly specialized types that are found nowhere else on Earth. [32] Relative humidity is high throughout the entire year; usually exceeding 90%. 12 nmi (13.8 mi; 22.2 km) Wild tigers, Eld's deer, wild water buffaloes and hog deer are at critically low numbers. Highlands to the north-east and to the east merge into the Central Highlands and the Mekong Delta lowlands of Vietnam. This area of greatest rainfall, however, drains mostly to the sea; only a small quantity goes into the rivers flowing into the basin. [29][30], A heavily indented coastline at the Gulf of Thailand of 443 km (275 mi) length and 60 offshore islands, that dot the territorial waters and locally merge with tidal mangrove marshes - the environmental basis for a remarkable range of marine and coastal eco-regions. The most widely accepted length is 440 km (273 mi), a 1997 survey by the DANIDA organization announced a length at 435 km (270 mi), and in 1973 the Oil Authority found the coast to be 450 km (280 mi) long. As humans preferably settle in these fertile and easily accessible central lowlands, major transformations and widespread cultivation through wet-rice agriculture have over the centuries shaped the landscape into distinctive regional cultivated lands. Boasting warm and friendly service, gorgeous nautically-inspired cruise ships, and extraordinary itineraries, Holland America cruises are perfectly designed for … total: The highest mountain of Cambodia, Phnom Aural, at 1,810 m (5,940 ft) is located in Aoral District in Kampong Speu Province. The meadows are highly productive, but few animals feed directly on the grasses. Arenosols (sandy soils featuring very weak or no soil development) are mapped on only 1.6% of the land area. The Mekong River drains more than 313,000 square miles (810,000 square km) of land, stretching from the Plateau of Tibet to the South China Sea. Cambodia is a country in mainland Southeast Asia, bordering Thailand, Laos, Vietnam, the Gulf of Thailand and covers a total area of 181,035 km2 (69,898 sq mi). [38][39] The Mekong branches off into several arms near Phnom Penh and reaches Vietnamese territory south of Koh Thom and Loek Daek districts of Kandal Province. Those that do tend to be vertebrates such as sea turtles, dabbling ducks and geese. [88] [nota 2] Um de seus afluentes, o rio Tonle Sap, é responsável por ligá-lo ao grande lago no centro do Camboja, que também é chamado de Tonle Sap. Answer: Cambodia. ], is remarkably rich in biodiversity. [71] The central Tonle Sap, the Great Lake has several input rivers, the most important being the Tonle Sap River, which contributes 62% of the total water supply during the rainy season. [99] The area’s extensive wetland habitats are the product of the annual Mekong maximum, the simultaneous wet season and the drainage paths of a number of minor rivers. Hong Kong Observatory, 2003. [17][18][19], The Indochina continental block, which is separated from the South China Block by the Jinshajiang-Ailaoshan Suture zone, is an amalgamation of the Viet-Lao, Khorat-Kontum, Uttaradit (UTD), and Chiang Mai-West Kachin terranes, all of which are separated by suture zones or ductile shear zones. [96] Quiz about Bridges . Cambodia borders Vietnam over a length of 1,228 km (763 mi), Thailand over a length of 803 km (499 mi) and Laos over a length of 541 km (336 mi), with 2,572 km (1,598 mi) in total and an additional 443 km (275 mi) of coastline. Founded in 1607 by Spanish explorers. A few characteristic basalt hills are located on the northern side of the mountain chain. The plain's deepest point - the Tonle Sap - flooded area varies from a low of around 2,700 km2 (1,000 sq mi) with a depth of around 1 meter at the end of the dry season (April) to 26,000 km2 (10,000 sq mi) and a depth of up to 9 meters in October/November. Overview of the Mekong River and its declining fish population. The main cause of deforestation has been determined to be large-scale agricultural expansions. [25][26] Domestic plants, such as sugar palms, Coconut trees and banana groves almost exclusively skirt extensive rice paddies, as natural vegetation is confined to elevated lands and near waterways. [108][109][110][111], "The 1993 Royal Decree on the Protection of Natural Areas recognized 23 protected areas, which at the time covered more than 18% of the country’s total land area."[112]. Angkor Wat (bahasa Khmer: អង្គរវត្ត, "candi kota") adalah sebuah gugus bangunan candi di negara Kamboja yang merupakan salah satu monumen keagamaan terbesar di dunia. The upper section, above Chau Doc (Chau Phu), has strong natural levees (embankments built on either side of the river by accumulated deposits of silt) behind which are low, wide depressions. Water levels, not flow rates and volumes, determine the movement of water across the landscape."[37]. Threats to the lake include widespread pollution, stress through growth of the local population which is dependent on the lake for subsistence and livelihood, over-harvesting of fish and other aquatic - often endangered - species, habitat destruction and potential changes in the hydrology, such as the construction and operation of dams, that disrupt the lake's natural flood cycle. Sandy textured profiles are common amongst the most prevalent soil groups, including Acrisols and Leptosols. 200 nmi (230.2 mi; 370.4 km), Elevation extremes: It has a length of about 2,700 miles (4,350 km). The landscape has suffered from rubber farming, logging and particularly mining, although sizable areas of pristine jungle survive, which are home to rare and endemic wildlife. In November the lake reaches its maximum size. Moisture-laden monsoon winds, that blow in from the Gulf of Tonkin ensure permanent high air humidity. Interlocking forest, - grassland and marshland patches provide the many facets and refugia for the abundant local wildlife. [35], The plains of the Mekong and Tonle Sap basin are confined in the North by the Dangrek and Central Annamite Mountains, and to the South by the Cardamom Mountains and Elephant Mountains. lowest point: The middle section has some areas that are well drained, others that are poorly drained and swampy. The mean annual reverse flow volume in the Tonle Sap is 30 km3 (7.2 cu mi), or about half of the maximum lake volume. The Dâmrei (Elephant) and Krâvanh (Cardamom) mountains in southwestern Cambodia constitute the southern highlands. Mekong River, Cambodian Mékôngk, Laotian Mènam Khong, Thai Mae Nam Khong, Vietnamese Sông Tiên Giang, Chinese (Pinyin) Lancang Jiang or (Wade-Giles) Lan-ts’ang Chiang, river that is the longest river in Southeast Asia, the 7th longest in Asia, and the 12th longest in the world. Throughout most of the distance between Ky Son (Muong Sen) in northern Vietnam and Ban Hèt in southern Laos, the watershed forms the border between Vietnam to the east and Laos to the west. Along its course between Myanmar and Laos, the Mekong drains about 8,000 square miles (21,000 square km) of territory in Myanmar, comprising rough and relatively inaccessible terrain. [100] Considering the eco-region's importance, a variety of plans for local wetland management consolidation exist[101][102] with varying degrees of completion. Chhung Kompong Som, Gulf of Thailand, Mekong River, San River, Sen River, South China Sea and Tonle Sap. The watershed along the escarpment in general terms marks the boundary between Thailand and Cambodia, however there are exceptions. Gradual silting of the lake would seem to be occurring; during low-water level, it is only about 1.5 m (4.9 ft) deep, while at flood stage it is between 10 and 15 m (33 and 49 ft) deep. "Climatological Information for Sihanoukville, Cambodia", After extensive rapids, turbulent sections and cataracts in Laos, the river enters the country at Stung Treng province, is predominantly calm and navigable during the entire year as it widens considerably in the lowlands. Local people, however, tended to use the forest's sustainability, for food, fuel, medicine, building materials, and other basic needs.

In the dry season when the floods subside, the Sab reverses its flow to drain southeastward into the Mekong. The Mekong's waters disperse into the surrounding wetlands of central Cambodia and strongly affect the seasonal nature of the Tonlé Sap lake. [50] Forest fires are common during the dry season. 176,515 km2 (68,152.8 sq mi) At Phnom Penh, Cambodia, the Mekong River joins a huge natural reservoir. Vientiane (Viangchan), the capital of Laos, and Phnom Penh, the capital of Cambodia, both stand on its banks. The bowl's bottom represents Cambodia's interior, about 75 percent, consisting of alluvial flood-plains of the Tonlé Sap basin, the lower Mekong River and the Bassac River plain, whose waters feed the large and almost centrally located wetlands. Municipalities and districts are the second-level administrative divisions of Cambodia. The floodplains in turn are surrounded by low hills, covered with evergreen seasonal tropical forest with substantial dipterocarp vegetation or deciduous dry forest. [98], Wetlands cover more than 30% of Cambodia. Extending 110 km (68 mi) north from the Gulf of Thailand, they reach a high point in the Bok Koŭ ridge at Mount Bokor 1,081 m (3,547 ft) near the sea.[46][47][48][49]. Extensive rapids run north of Kratie city. The Royal Government of Cambodia estimates Cambodia contains approximately 10.36 million hectares of forest cover, representing approximately 57.07% of Cambodia’s land area (2011). Cambodia's territorial waters account for over 50 islands. [76] On the contrary, international observers and independent sources provide rather different numbers. Coauthor of. Approximately how many bridges can one find in Venice, Italy? "[104], "Until relatively recently, the mangroves of Koh Kong, Cambodia have remained relatively intact. [105][106][107], "With their roots deep in mud, jagged and gnarled mangrove trees are able to grow in the brackish wetlands between land and sea where other plant life cannot survive. Between the falls and Krâchéh there are rapids interspersed with alluvial plains. Tropical cyclones only rarely cause damage in Cambodia. Essentially the southern escarpment of the sandstone Khorat Plateau of northeastern Thailand, the Dângrêk range slopes gradually northward to the Mun River in Thailand but falls more abruptly in the south to the Cambodian plain. The plains completely surround the Tonle Sap Lake in the western half of the country and wind their way through the middle of the country following the course of the Mekong River. Rainfall from April to September in the Tonlé Sap Basin-Mekong Lowlands area averages 1,300 to 1,500 mm (51.2 to 59.1 in) annually, but the amount varies considerably from year to year. The annual monsoon coincides to cease around this time of the year. [77][78][79], Figures and assessments are numerous as are available sources. The Cardamom Mountains form - including the north-western part of Chanthaburi Province, Thailand, the 'Soi Dao Mountains' - the Cardamom Mountains Moist Forests Ecoregion, that is considered to be one of the most species-rich and intact natural habitats in the region. About three-fourths of the drainage area of the Mekong lies within the four countries the river traverses on its lower course—Laos, Thailand, Cambodia, and Vietnam. [91] The forest gradually yields to bushes and finally grassland with increasing distance from the lake. O fluxo de água no Mekong durante a estação seca é de 15 000 m³ por segundo, [ 87 ] enquanto no resto do ano, pode chegar até a 60 000 m³ por segundo em Phnom Penh. In addition to the Mekong River and the Tonle Sap floodplain there are the Stung Sen River and the coastal Stung Koh Pao - and Stung Kep estuaries of Koh Kong Province and Kep Province. [16] The Indo-Sinian orogeny was followed by extension of the Indo-Chinese block, the formation of rift basins and thermal subsidence during the early Triassic. [80] Approximately 40% of Cambodia’s Forests have some level of protection, while one of the Cambodia Millennium Development Goals targets is to achieve a 60% forest cover by 2015. Overall Cambodia’s forests contain an estimated 464 million metric tonnes of carbon stock in living forest biomass. As the Mekong enters Cambodia (over 95% of its waters have already joined the river) it widens and inundates large areas. Bowl- or saucer-shaped,[23][24] Cambodia covers 181,035 km2 (69,898 sq mi) in the south-western part of the Indochinese peninsula as its landmass and marine territory is situated entirely within the tropics. Although its waters increase in volume during the rainy season, these are not swelled by the streams from the mountains on its western boundary, but by the strength of the current from the Mekon which pours into it its overflow. The river divides into two branches below Phnom Penh: the Mekong proper and the Bassac (Basak). Celebrity Cruises from Sydney, Melbourne, Auckland, and more! [114], Cambodia's boundaries were for the most part based upon those recognized by France and by neighboring countries during the colonial period. The Mun River—one of the Mekong’s most important tributaries—drains the majority of the plateau and joins the Mekong at Ban Dan, Thailand. [74][75], Cambodia has one of the highest levels of forest cover in the region as the interdependence of Cambodia’s geography and hydrology makes it rich in natural resources and biological diversity - among the bio-richest countries in Southeast Asia. [94][95], The lake’s flooded forest and the surrounding floodplains are of utmost importance for Cambodia's agriculture as the region represents the cultural heart of Cambodia, the center of the national freshwater fishery industry - the nation's primary protein source. They divide into two parallel channels, the Mekong River proper and the Bassac River, and flow independently through the delta areas of Cambodia and Vietnam to the South China Sea. The river then flows through Laos, Cambodia, and Vietnam before draining into the South China Sea south of Ho Chi Minh City (formerly Saigon). The main subgroups are: Gleyic Acrisols (20.5%, Haplic Acrisols (13.3%), Plinthic Acrisol (8.7%) and Ferric Acrisol (6.3%).
