基于目标库容曲线的水库出流模拟模型
Reservoir outflow simulation model based on reservoir target capacity curve
摘要
Abstract
With the continuous construction of reservoirs,the impact of reservoirs on the water cycle is more and more significant,and the outflow process of reservoirs has become an important part of the land water cycle.In order to simulate the impact of Reservoir on water circulation,Reservoir Outflow Simulation Model(ROSM)should be constructed to simulate the outflow of reservoir.However,the current proposed ROSMs have weak gen-erality and are only applicable to reservoirs with preset operation mode.In this paper,it is assumed that the goal reservoir capacity at various times of the year forms a Target Capacity Curve(TCC).The generality of ROSM can be improved by setting different TCCs for different reservoirs.Two model structures are proposed to consider the influence of TCC on reservoir discharge from two aspects:(1)The reservoir tends to store water and the outflow decreases in the season with higher target storage capacity,while the reservoir tends to release water and the out-flow increases in the season with lower target storage capacity.(2)The outflow of the reservoir should make the actual water storage close to the target storage capacity.According to the two model structures,four kinds of TCC-based ROSM were constructed,and the common ROSM were applied to 26 reservoirs in the Yangtze River,Pearl River and Yellow River basins.The results showed that:(1)the performance of the outflow simulation and water storage simulation of the ROSM considering the two model structures was optimal,indicating that the struc-ture of the two models was reasonable and effective;(2)Considering that the simulation accuracy of TCC ROSM in multi-year and annual regulation reservoirs is far higher than that of other ROSM,it indicates that TCC can ef-fectively improve the simulation accuracy of these two types of reservoirs and improve the versatility of ROSM.关键词
