北东洲水库泥沙淤泥预测模拟研究

Study on Sedimentation Prediction Simulation of Beidongzhou Reservoir

通过实际测量获取北东洲水库水位-库容-淤积量关系,采用Gauss3模型进行拟合分析,获取不同水位处淤积量。结合实测数据,采用平均输沙率模拟预测不同情况下的泥水淤积情况,除非发生特殊自然灾害,实际发生淤积值不会高于模拟情况。随着流域植被增加,淤积量减少,水库淤积情况明显改善。

The relationship between water level-storage capacity-siltation amount of Beidongzhou Reservoir was obtained through actual measurement,and the GAUSS3 model was used for fitting analysis to obtain the siltation amount at different water levels.Combined with the measured data,the average sediment transport rate is used to simulate and predict the siltation of mud and water under different conditions.Except for special natural disasters,the actual siltation value will not be higher than the simulated situation.With the increase of vegetation in the basin,the siltation amount will decrease,and the siltation of the reservoir will be significantly improved.
