一种基于栅格的新安江模型中参数B的计算方法

istributed hydrology model is still a hotspot nowadays, but it’s development is restricted by optimizing parameters. It behaves as it’s difficult to find the relationships between the parameters and basin feature. So this paper gives a method to calculate the value of B in Xin’anjiang model based on DEM grid according the comparability of terrain index and the water saving graph.
