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 本論文以廣西紅水河龍灘水電站為例,在第一篇中采用洪水過程線法計(jì)算了給定設(shè)計(jì)頻率為0 . 01 、 0 . 1 、 0 . 2和1的壩址設(shè)計(jì)洪水,并利用合成流量法計(jì)算了相應(yīng)設(shè)計(jì)頻率的入庫設(shè)計(jì)洪水。
