摘要
该文旨在使用数字高程模型(DEM)计算库容的方法,并利用水量平衡方程进行变时段的调洪演算,从而达到计算水库水位的目的。与传统方法相比,DEM数据可根据库容变化迅速修正,故本方法具有计算速度快、可及时修正模型得到精确结果的优点。
The paper introduces a method to calculate the capacity of reservoirs through Digital Elevation Model (DEM) and the reservoir flood routing calculation, which utilizes the equation of water amount balance with different period of time. Contrasted to the traditional method, the data of DEM can be quickly adjusted with the changing of the capacity of reservoirs, therefore it has the advantages of both rapid computing speed and the accurate result by regulating the model in time.
