Vietnam is situated in South - East Asia with its main land lying between north parallels 80 - 230 and east meridians 1020 - 1090 . It has a territory of 331 000 km2 and a population of 83 mil. . The country s mountainous topography three-quarters are mountains and hills and subtropical humid monsoon climate profoundly affect the quantity and distribution both temporally and spatially of water. Vietnam in South - East Asia Water Resources Distribution. Mean annual rainfall which almost is the only source of surface flow is about 2 000 mm but about 75 acumulates in only three months more than 30 usually in only one peak month . This occurs from July to September in the Northern and Southern areas and from September to December in the Central area. The mean annual runoff totals 880 billion m3 ranking 12th in the world of which 70 is generated outside the border lines and flows downstream into Vietnam. The mountainous landscape offers substantial potential for hydropower and water storage. In wet seasons this promotes rapid flood concentrations makes heavy inundation in alluvial plains and deltas where most big cities are located. In dry seasons there are water shortages the minimum monthly flow of most basins is just 1 of annual runoff and drought which threaten the water supply and living condition of millions people with impacts on environment agriculture aquaculture etc. Location of some large dams Legend H Dam height V Water stOrage volume Tuyen Quang CFR Dam H93m P342MW RECEIVER r P Power capacity Existing Dams Dams . under construction Son La RCC Dam H138m P2400MW D 9 Hoa Binh CCR Dam fe H128m P1920MW Cua Dat CFR Dam H119m P98MW laly CCRDam H69m P720MW Easoup Earth Dam H27m I Ĩ -r w I Ban Ve RCC Dam H1379m Phuoc Hoa Weir H28m Phu Ninh Earth Dam H40m Dinh Binh RCC Dam H53m HO .
