  1. When catchment area, average channel gradient and catchment shape factor of designed culvert or bridge are known, a user can be convenient to get local parameters c, e and b from standard contour charts and easy to calculate flood flow just by a calculator. design period of flood flow is enormously shortened as well as a high precision. estimated flood flow through culvert or small bridge by new calculation model is generally less than by traditional methods, so that much cost is cut down a s reducing the span of culvert or small bridge

    以75000km ~ 2的川中丘陵地區為試點研究區，繪制了該地區新模型的參數等值線圖，率定了不同設計頻率的改正系數，使設計者只需在地形圖上獲取集水面積，河道平均坡降和流域形狀系數，在參數等值線圖上查得橋涵所在地的相應參數，使用計算器即可迅速計算出設計流量，大大縮短了設計周期，且精度較高，設計的洪水流量一般低於傳統方法，從而可減小橋涵跨徑，節省投資。

    滑動汛期水位在多年資料基礎上，通過統計汛期中每日為起點的最大來水量，求出固定頻率的設計來水量，選擇合適的典型洪水過程線進行調洪計算后得到每天的汛限水位。
  4. 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
