MetadataShow full item record
Flood is natural process which can become catastrophic when the flood plain and catchment areas are occupied and constructed by the human being. Along with rapid population growth, natural source management has been changed and has led to flood risk. Forested upstream area which has been changed to farmland and housings diminishes the function of the catchment area in infiltrating and catching the water. The bare land with no vegetation leads to erosion risk and increases the potential risk of damages. In addition, this condition increases the water velocity and leads to land scour as well as landslide. Good coordination among stakeholders such as the related institutions, private sectors, and local community is strongly required in preventing the floods. Furthermore, flood control should be conducted comprehensively involving multidisciplinary approach, and taking into account of some aspects such as technical, social, law, economic, and environmental. Therefore, cooperation and coordination among stakeholders is definitely needed in order to achieve integrated and sustainable flood management.
