摘要
本文根据流域蓄泄关系和霍顿地貌律 ,建立了基于概念性线性水库原理的流域汇流模型 ,以三级为例推导了流域的数学模型 ,并对模型进行了讨论和改进 ,用河北尚义流域 (半干旱地区 )和福建古田溪梯级电站流域 (湿润地区 )对模型进行了检验 ,结果表明
A watershed routing model was established with the storage-outflow relationship of the watershed and the Horton geomorphologic law,and based upon the principles of conceptional and linear reservoir.Firstly,the mathematics model of the watershed was derived,in which the instantaneous unit hydrograph of the three-order watershed was taken as an example,then the model was modified and discussed.Finally,the model was tested with its application in Shangyi watershed (located in semihumid area,Hebei Province)and in Gutian River(located in humid area,Fujian Province),the result demonstrates that the model is feasible.
