摘要
对高含沙地区中小水库的淤积发展提出了一个数学预估模型,通过对解放沟水库的实测淤积资料与模型的淤积计算对比分析,该模型基本上能够反映该水库的泥沙变化规律,也为水库管理单位预估泥沙发展提供了一种新的数学计算方法。影响数学模型的因素采用K、b、c三个综合参数表示,参数确定后,淤积面积主要是与相对水深的关系,经过计算,解放沟水库的实际淤积量与计算淤积量的误差范围在6%左右,基本上能够反映水库今后的淤积变化。
A mathematical model is proposed for forecasting the development of sediment deposition in small and medium reservoirs of hyper-concentration areas. Through a comparative analysis for the measured deposition data in Jiefanggou Reservoir and calculation results of the model, it is shown that the model could reflect the sediment variation law in the reservoir, and provide a new method for computing and forecasting the development of sediment deposition for reservoir management units. The factors affecling the mathematical model are expressed by three synthetic parameters K, b, c. The deposition area is mainly relative to the depth of water. It is known by calculation that the error between the mea- sured deposition capacity and computed deposition capacity from Jiefanggou Reservoir is about 6 %, which could basically reflect the future variation of sediment deposition in the reservoir.
