漳河流域气象水文预报模型研究

Study on Meteorology-Hydrology Forecast Model in Zhang River Valley

通过对漳河产流、汇流、河道汇流和水库调洪演算,建立了漳河流域气象水文预报模型。本模型可根据实测降水量预报未来一定时期内入库洪水总量、洪峰、峰现时间、入库洪水过程,考虑水库出流及串联水库水量交换,经调洪演算得出水库水位变化过程。同时,也可输入气象预报的降水量或人工估算的未来可能降水量,进行水库未来洪水的可能发展趋势预测。

By the calculation of water yield, conflux, riverbank conflux, flood routing of reservoir in Zhang river valley, the paper sets up meteorology-hydrology forecast model of Zhang fiver valley. Based on the actual precipitation, the model can forecast reservoir flood, flood peak, arisen time of flood peak, reservoir flood process, and in view of outlet flow of reservoir and serieswound reservoir water exchange, it can find the process of reservoir water level through the flood routing calculation. At the same time, if the precipitation of meteorological prediction or future possible precipitation of manual estimation is inputted to the model, the possible development trend of reservoir future flood can be forecasted.
