Extended Application of the Discharge Coefficient in the Muskingum Flood Routing Method

It is proposed in this paper that the discharge coefficient K,x in Muskingum Flood Routing Method based on long-term flood routing can also be used on the short-term one of the same river reach. Thus, some special demands in water conservancy and hydroelectric design as well as the approximate calculation problems of unsteady flow for daily-regulation of the hydropower station are resolved. The physical foundation of this method is assuming the riverbed as a prism. The analysis of observed data shows that this method meets the requirement in planning and designing work of projects with higher calculation precision.
