0%)典型年。进行年及各枯水时段同频率缩放，得出天堂岩站三个代表年的逐日平均流量。将天堂岩站代表年逐日平均流量按面积比拟加雨量修正方法移算到工程坝址处，即获得毛坪水电站坝址处丰(10%)、中(50%)、枯(90%)三个设计代表年逐日平均流量成果。三个设计代表年逐日平均流量成果见下表：11毛坪水电站设计丰水年(P=10%)逐日流量表日/月5678910111212341,0.1930.5422.9030.5530.5770.7940.5850.4680.5630.5040.3830.2632,0.1900.7661.6531.2280.5690.7310.5620.4840.5330.4960.3830.3413,0.1960.7590.9681.7550.5440.7890.5550.4960.674
