Analysis on Required Runoff to Maintain the Main Channel for Medium Flood in the Lower Weihe River
Weihe River is the biggest tributary of the Yellow River. Medium and small flood disasters frequently occur due to the serious lack of water in the recent years, sedimentation, main channel shrinkage and serious deduction of discharge capacity. In order to reduce the pressure on flood prevention, it is necessary to shape and maintain a certain river channel for medium flood in the Lower Weihe River. According to the requirement on the discharge capacity of the Lower Weihe River channel by sustainable development of social economy, analysis on the frequency of medium flood and forecasting of runoff and sediment in future, the paper discusses the standard of the main channel for medium flood, annual runoff, water volume in flood season and flood volume that is required to maintain the main channel for medium flood in the Lower Weihe River. It is hoped to give reference to trans-basin water transfer and analysis on required water volume of intake area.
