摘要
根据新安江模型理论,构造了基于栅格的新安江模型,该模型以DEM栅格为计算单元,考虑栅格之间的水量交换以及河道排水网络的影响,并将模型用于钱塘江支流密赛流域以及淮河息县流域的洪水模拟计算,结果表明,该模型可以很好的应用上述两个流域进行洪水模拟,其模拟精度与传统新安江模型的模拟精度相当。栅格型新安江模型可以很好的模拟流域水文过程的空间分布,通过比较几次洪水的产流面积变化过程可以看出,栅格型新安江模型的模拟结果与新安江模型的模拟结果基本一致,证明了该模型的合理性。
Based on the theory of Xinanjiang model, the grid-based distributed hydrologic Xinanjiang model （Grid- Xinanjiang model） is developed. The water exchange among the grids and the influence of the river drainage network can be considered. The studied catchments are located in humid religions of Misai basin and Xixian basin. The simulated results show that the accuracy of the grid-based model is higher and it is almost the same with the simulated accuracy of original Xinanjiang model. The area variation of hydrological process can be simulated by Grid- Xinanjiang model. The two time curves of runoff area variation simulated by Grid-Xinanjiang and Xinanjiang models are the same and it shows that Grid-Xinanjiang model is reasonable.
