Abstract

The lower Mekong River flooded from July to December in 2000. Especially, Cambodia and Vietnam were serious on inundation. The numbers of victims were 347 in Cambodia and 448 in Vietnam. The amounts of damage were 80 million and 350 million US dollars in Cambodia and in Vietnam, respectively. Water level reached to a record-breaking height at Phnon Penh. The main reasons of this flood were that heavy rainfall began earlier and two tropical cyclones approached to the catchment area. Other reasons were that some portions of dikes were changed to bridge to protect roads, Colmatage worked as intake from the main river and sedimentation deposited in channels and canals. Governments and international organizations are designing and planning some projects for flood control.
