通过对沙河市丘陵区2.6 km 2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。
通過對沙河市丘陵區2.6 km 2的特小流域設計洪水計算,闡述特小流域的計算方法,同時對特小流域暴雨洪水計算的影響因素及特點進行瞭總結,為無資料特小流域設計洪水計算提供參攷依據。河北省丘陵地形分佈較廣,建設水利工程或其他小工業企業,集雨麵積為特小流域的情況普遍存在,而針對特小流域的洪水計算方法研究,對于小型水庫、塘壩等小型水利工程的規劃設計具有重要應用價值。
