| Abstract | A study was conducted at sub-basin level of the Lower Mekong Basin to assess the water availability in the area that can be used for different beneficial purposes. The present water use in the domestic, industrial and agricultural sectors at the sub-basin level was also assessed, and their projection in the future was made. The data on water resources availability and use were collected mainly through secondary sources. The Lower Mekong Basin was delineated into twenty-four major sub-basins for the purposes of data analysis and presentation, which is in accordance with the prevailing major sub-catchment delineation followed by the National Mekong Committees of the four riparian countries. Runoff factor method was used to generate the runoff for sub-basins having no observed runoff data. The future water demand for domestic, industrial and irrigation sectors was estimated using appropriate techniques. The study revealed that there exists a huge potential of water resources development in the Basin. However, the temporal and spatial variations make some of the sub-basins in water scarcity situation. It was found that out of 24 sub-basins, 7 sub-basins which comprise of about 49 percent of the study area are facing with inadequate water supply that occurs especially during the dry season from December to May. These sub-basins are located mostly in the central and lower part of the Lower Mekong Basin, particularly in the Mekong Delta. For example, the most severe water shortage in dry season of 1,306 mcm and 5,812 mcm occurred at Mekong Delta sub-basin in Cambodia and Vietnam respectively. A detailed water supply and demand analysis was carried out for the upper Srepok sub-catchment (12,080 km2) in Vietnam. MIKE Basin model was applied to analyze the water resources availability and use in the sub-basin. It was found that with the existing irrigation schemes in upper Srepok sub-basin, there is no water shortage for the whole region, except for a small area (Krong Buk tributary catchment) covering about 4% of the sub-catchment. For the proposed increase in irrigation area in 2010, the analysis showed that water shortages will occur in Krong Buk and Krong Pak catchment comprising about 10% of the upper Srepok basin area. |
