在半干旱半湿润地区,其降雨径流的形成过程十分复杂,既有蓄满产流,又有超渗产流。为了适应这种复杂的降雨径流的形成机制,建立适用于超渗产生地表径流和超蓄产生壤中流的“双超”产汇流模型,并将其应用于山西省古县小流域洪水模拟预报。计算结果表明,该模型模拟预报的洪水过程与实测洪水过程基本吻合。 In the semi-arid and semi-humid areas, the formation of rainfall runoff is very complicated, both of which are full of runoff and ultra-runoff. In order to adapt to the formation mechanism of such a complex rainfall runoff, a model of “double super ” production and convergence suitable for the production of surface runoff and superfluid medium runoff by hyperosmosis was established and applied to the flood simulation of the small watershed in Guxian County, Shanxi Province forecast. The calculation results show that the flood process simulated by the model is in good agreement with the measured flood process.
