| Research Abstract |
This study aims to propose improvement measures of flood control and water use for existing multi-purpose dams. Functions of dams will be enhanced by temporary change of a capacity from water use to flood control, while that from flood control to water use as well as environmental recovery and small hydro-power. Improvement of functions of the existing facilities gives a promise as an effective measure because unexpected flood and drought due to future climate change are expected as well as new facilities are difficult to be developed.
The former means an operation to enhance the flood control capacity by prior releasing from dam reservoir when flood is predicted, while the latter means an operation to keep more water than the normal capacity for water use for utilization to small hydro-power etc. Both are required an accurate prediction of rainfall and inflow to dam reservoir, thus improvement measures of dam functions using such information were proposed.
