| 摘 要： | 利用基于栅格分布的土地利用类型和土壤类型,通过将SCS模型改进为栅格式的SCS模型,并结合栅格式Clark单位线汇流方法,构建了一个具有松散耦合型分布式水文模型.该模型结构简单,模型参数较少,所需流域特性资料容易获取,对流域具有较强的适应性,并可以获得流域栅格分布式的产流结果.本研究将该模型应用到欧阳海流域上,构建洪水预报模型进行场次洪水过程模拟,并与新安江模型模拟结果进行对比.模拟结果表明,所构建的松散结构分布式水文模型具有较高的模拟精度,能够应用到实际的洪水预报中.

| Abstract: | By using the land-use and soil-type raster data and by improving the original SCS model to Raster-based SCS model,together with the use of the raster-based Clark's unit hydrograph,a raster-based distributed hydrological model is built.The new model is relatively simple in its structure and few in its number of parameters.It has a strong adaptability,whose geographic information needed is easy to get;and it can have a raster-distributed runoff result of the watershed.The new model is applied to the flood for... |
