In the year 2006, the floods that occurred in Maharashtra and Gujarat were due to the aggravation of floods by the opening of gates of dams. The major cause of this was the sedimentation in the reservoir. Short-term measure to avoid this could be better management of dams, issuing a warning to the people regarding heavy rains, making arrangements for them for minimising human damage, etc. Long-term measures include - adapting the rain water harvesting systems both in urban areas and villages. 1) Using the roof top system rain water can be used in a proper way and floods can be prevented. 2) Underground water tanks if made in every house, will help in storing water in the case of heavy rainfall.
