沙河市特小流域设计洪水计算

Design Flood Calculation in the Mini-Basin of Shahe City

通过对沙河市丘陵区2．6km2的特小流域设计洪水计算，阐述特小流域的计算方法，同时对特小流域暴雨洪水计算的影响因素及特点进行了总结，为无资料特小流域设计洪水计算提供参考依据。河北省丘陵地形分布较广，建设水利工程或其他小工业企业，集雨面积为特小流域的情况普遍存在，而针对特小流域的洪水计算方法研究，对于小型水库、塘坝等小型水利工程的规划设计具有重要应用价值。

Through the research on design flood calculation in the mini-basin with drainage area of 2. 6 km3 in hilly region of Shahe City, the cal- culation method of design flood in mini basin was described. The influence factors and characteristics of storm flood calculation in the basin were also summarized,which could provide reference for design flood calculation in mini-basin without the relevant data. As the hilly land was widely distributed in Hebei, the phenomena of the mini-basin that formed by the hydraulic engineering or other small industrial enterprises were widely existed in the Province. Study on the design flood calculation method in the mini-basin has a high value practical application in designing and planning of small hydraulic engineering, such as small reservoirs, embankments and so on.
