Because of lack of trained manpower and funds third world countries in humid tropical areas have bad problems with water managment. The major problems faced are flooding, soil erosion and pollution. Flooding can be controlled with dams and levees. Soil erosion can be controlled by careful deforestation techniques, seedbed reparation, and runoff and crop managment. Pollution can be controlled by industry and government measures which is unlikely to occur because of pressure to promote industry. Pollution can be avoided in drinking water by exploitation of groundwater aquifers in place of contaminated river water.
