1、课程设计一推求设计年径流(一)资料：已知某拟建水库坝址处逐年月平均流量表(见下表一)(二)要求：(1)如果设计水库的年径流设计保证率为p=90%，丰水采用p=10%，平水采用p=50%试用频率分析法求丰平枯的设计年径流值。(2)根据设计年径流成果，选择典型年，用同倍比方法推求p=90%的年径流过程。(三)交阅成果：(1)频率分析计算表。(2)频率分析适线图。(3)频率p=90%的设计年径流过程。表一年月径流过程表月年345678910111212年平均1930—3112121421616160.228.869.046.715.641.437.615597.231—321311053001681
