设计洪水是确定水利水电工程规模的重要因素。伴随着经济社会的发展，小河流综合整治逐渐开展，但是，小河流往往缺乏实测的水文气象资料，常用的做法是通过查等值线图，利用综合单位线法和推理公式法分别计算，然而在解决集雨面积相近的两条小河流汇合口处设计洪水时却存在一个问题。为此，文章在总结目前常用的小河流设计洪水计算方法的基础上，结合广东省实际情况，通过实际范例，初步探讨出集雨面积相近的两条小河流汇合口处设计洪水的计算方法。
設計洪水是確定水利水電工程規模的重要因素。伴隨著經濟社會的髮展，小河流綜閤整治逐漸開展，但是，小河流往往缺乏實測的水文氣象資料，常用的做法是通過查等值線圖，利用綜閤單位線法和推理公式法分彆計算，然而在解決集雨麵積相近的兩條小河流彙閤口處設計洪水時卻存在一箇問題。為此，文章在總結目前常用的小河流設計洪水計算方法的基礎上，結閤廣東省實際情況，通過實際範例，初步探討齣集雨麵積相近的兩條小河流彙閤口處設計洪水的計算方法。

The design flood is an important factor in determining the scale of the hydro-project.With the economic and social development, the comprehensive improvement of the small rivers is gradually carried out.But it is often lack of the hydrologic and meteorological data actually measured for small rivers.The common practice is through the examination of the contour map.Then it is calculated separately by the synthetic unit hydrograph method and the inference formula method.However,there is a problem in solving the design flood of the confluent mouth for the two small rivers with the close water-collecting area.At the basement of summarizing the currently common calculation method of design flood for small rivers, combined with the actual situation in Guangdong Province, there is a preliminary discussion on the calculation method of the design flood of the confluent mouth for the two small rivers with similar water-collecting area through a test.
