Thus , the next 1500 hours correspond to the base flow recession period . it is obvious that the aquifer with ampler water storage will produce larger subsurface runoff . from the above numerical simulations , one can see that the b - s model can reasonably simulate the subsurface runoff varia - tion in the two extreme conditions 而在持續了1500 h以后入滲突然都變為0對應著實際情況中徑流的消退期,顯然儲水較多的潛水面的地下徑流比較大,而隨著退水的持續進行行,地下徑流也越來越小
