Hydrological and Hydraulic Calculation Analysis of Yangchuan River Regulation Project in Guizhou Province
The rocky desertification area in Guizhou has serious water and soil loss,and the sediment content of runoff after rainstorm is high,which often causes serious siltation of the river channel,which leads to the decline of the flood carrying capacity of the river channel and water environment pollution.Therefore,the dredging project is need to implement.Due to the lack of measured hydrological data in small river basins and the development of karst landforms in the local area,traditional runoff calculation models have insufficient parameters and significant deviations.Therefore,empirical formulas are generally used to calculate design floods.Taking Yangchuan River main stream dredging project as an example,the typical hydrological and hydraulic calculation process of Guizhou mountainous river regulation project is introduced in detail from benchmark stations selection,design rainstorm and design flood calculation,flood calculation during construction period,and calculation of water surface profile after regulation.
