Research on 10-day run off forecasting for reasonable operation of Cua Dat reservoir

Abstract

     Cua Dat reservoir on the Chu River is located in Xuan My Commune, Thuong Xuan District, Thanh Hoa Province. For reliable operation of the reservoir to meet it's requirements of water supply, loss reduction and maximum power generation, a mid-term (10-day) runoff forecast is needed. This article proposes a forecast method which is a combination of water balance and reservoir operation models. It can be seen from the research results that there is not so good agreement between the simulated and observed runoff hydrograph but total volume of forecasted runoff and with observed one is almost equal. This can be explained because of lacking hydro-meterological data and electricity demand information.
