摘要
结合永嘉县五尺溪小流域降雨径流洪水特征,分别采用石柱站实测暴雨资料排频配线和《浙江省短历时暴雨》图集查算得到设计暴雨成果.成果表明频率适线法设计暴雨成果比查图法较大,分析了成果差异的原因,又通过对龙溪水库设计暴雨成果与五尺溪本次规划设计暴雨成果比较表明,二者均较为接近,从而在小流域规划设计推荐使用查暴雨图集算得的暴雨成果.
Combined with the features of rainfall runoff floods in Wuchi Creek watershed in Yongjia,design storm results are obtained according to the actual measurements of heavy rain and the atlas of＂Zhejiang short duration storm＂. Results show that the design storm by frequency curve-fitting method is heavier than that by figure-checking method,and the reason is also analyzed for the differences between the results. Compared the design storm results in Longxi Reservoir with the planning design storm in Wuchi Creek,the results are relatively close,thus the calculation by heavy rain atlas is recommended to design and check rainstorm in small watershed.
