以江垭水库某次洪水过程为例，探讨了洪水单位过程线的推求。由实际降雨量和流量过程线进行分析，并做了基本假定；所选的降雨洪水过程超过三个时段，且有一个最大值，故采用试错法进行推求，给出了推求过程及方法。将推求成果与降雨径流相关图配合使用，可对洪水过程进行预报。
以江埡水庫某次洪水過程為例，探討瞭洪水單位過程線的推求。由實際降雨量和流量過程線進行分析，併做瞭基本假定；所選的降雨洪水過程超過三箇時段，且有一箇最大值，故採用試錯法進行推求，給齣瞭推求過程及方法。將推求成果與降雨徑流相關圖配閤使用，可對洪水過程進行預報。

the paper took a flood process of Jiangya reservoir as an example, and discussed the derivation of flood unit hydrograph. Actual rainfall and flow process lines were analyzed, basic assumption was conducted; the selected rainfall flood process exceeded more than three periods, a maximum value was available, so error trial method was adopted to derive, the deriving process and methods were given. The derived achievements and rainfall runoff relevant chart were cooperated for use to forecast the flood process.
