Utilizing inactive storage in a dam reservoir during extreme drought periods

The purpose of this study is to suggest a structural plan for improving the utilization inactive storage in dam reservoirs, mitigate extreme drought. Inactive composed emergency and dead storage. can be used emergencies such as But, general, sedimentation not used, even an emergency. Therefore, we developed methodology determine how space partially during drought periods when has occurred yet. We call partial reservoir “drought storage”. An accurate analysis sediment levels needs performed before calculating storage, so present level was estimated using SED-2D linked with RMA-2 model SMS. After considering additional available capacity based on level, finally determined. also predicted future after 100 years amount future. As result, found that will lower compared due gradual increase over time dam. Further research may needed effectively reduce order capacity.
