乌江渡水电站产汇流分析及应用

Analysis and Application of Runoff Generation and Flow Concentration in Wujiangdu Hydropower Station

乌江渡水电站位于乌江中游,为了进一步了解乌江流域产流机制,加强应对突发意外情况时对流量变化的掌控,做好乌江渡水电站防洪预报工作,笔者从产流机制、产流方法、汇流机理和汇流方法对乌江流域进行深入的分析,将蓄满产流模型应用在乌江渡水库上,借用VB编程工具计算入库流量。举例计算了2018年一场降雨产生的径流,结果与实测数据对比,误差在可接受范围内,表明此编程模型适用于乌江渡水电站。

Wujiangdu Hydropower Station is located in the middle reaches of Wujiang River.In order to further understand the mechanism of runoff generation in Wujiang River Basin,strengthen the control of flow change in response to unexpected situations,and do a good job in flood control and forecasting of Wujiangdu Hydropower Station,the author makes a thorough analysis of the runoff generation mechanism,runoff generation method,flow concentration mechanism and flow concentration method in Wujiang River Basin,and applies the runoff generation under saturated condition model to Wujiangdu Hydropower Station,and the reservoir inflow is calculated by using VB programming tool.An example is given to calculate the runoff generated by a rainfall in 2018,the comparison between the calculated results and the measured data shows that the error is acceptable,and the programming model is suitable for Wujiangdu Hydropower Station.
