洪水过程线 meaning in Chinese

flood hydrograph
flood hygrograph
flood profile
floodhydrograph

By use of many years ' hydrologic data , the max , water quantity dated from every day may be counted in every year ' s flood season , and the designed water quantity corresponds to the definite frequency
滑动汛期水位在多年资料基础上，通过统计汛期中每日为起点的最大来水量，求出固定频率的设计来水量，选择合适的典型洪水过程线进行调洪计算后得到每天的汛限水位。
In the first part , we compute the site design flood of given design frequency ( 0 . 01 % . 0 . 1 % . 0 . 2 % and 1 % ) using the design flood hydrograph . then we get the design reservoir inflow flood of the same design frequency by the resultant discharge method . according to the computing value we compare the site design flood and design reservoir inflow flood of different time interval
本论文以广西红水河龙滩水电站为例，在第一篇中采用洪水过程线法计算了给定设计频率为0 . 01 、 0 . 1 、 0 . 2和1的坝址设计洪水，并利用合成流量法计算了相应设计频率的入库设计洪水。
