在利用暴雨资料推求洪峰流量和洪水过程线时,水利工程通常采用综合单位线、推理公式、经验公式、净雨过程法计算,而排水工程则采用《室外排水设计规范》(GB 50014—2006)及《城市水文学》中的公式计算雨水流量。两种专业方法并行存在了多年,各有其适用范围,但在实际使用中,相互间往往存在一定的误解,甚至误用。对水利工程和排水工程中降雨量计算、产流方法的来源和过程进行系统对比分析,表明两者的标准是同等意义的。此外,对各方法选用及参数优化、率定提出建议。
In the use of storm data to calculate flood peak flow and flood process line, water conservancy projects are usually integrated unit line, reasoning formula, empirical formula, net rain process method is calculated, and drainage projects are used “Outdoor Drainage Design Code” (GB 50014-2006) And “Urban Hydrology” formula to calculate the rainwater flow. Two professional methods exist in parallel for many years, each with its own scope of application, but in actual use, there is often some misunderstanding between each other and even misuse. The contrastive analysis of sources and processes of rainfall calculation and runoff method in water conservancy projects and drainage projects shows that the standards of both are of equal significance. In addition, each method selection and parameter optimization, rate set out recommendations.
