摘  要:
小流域设计洪水计算在工农业生产中具有重要意义。采用推理公式辽宁法计算白塔堡河的设计洪水流量,通过流域汇流历时与河长、比降的经验公式以及洪峰和洪量径流系数的相关关系,推求峰、量,再配以分段概化过程线,得到白塔堡河设计频率P=5%的洪水流量为272.27m3/s。

摘  要:
The calculation of design flood of small basins is of great significance to the industrial and agricultural productions. This article discusses the calculation of design flood of Baitapu River using rational formula. The flood peak and amount is determined according to the basin flow concentration time and the length of the river as well as the gradient empirical formula and the correlativity between the flood peak and the ratio of the runoff. Together with subsection generalizing hydrograph, the flood discharge of Baitapu River is obtained as 272.27 m3/ s when the design frequency P=5%.
