Several runoff calculation methods, including GAML revised by Chu, Phillip, Horton, SCS curve number, were compared. The results showed that the model efficiencies of GAML and Phillip were higher than those of Horton and SCS curve number.

• 结果表明 :GAML和Phillip计算结果的模型确定性系数较高 ,Horton入渗曲线和SCS曲线数的计算结果模型确定性系数偏低。
