摘要
依据漳河水库流域洪水汇流的实际情况,提出了流域汇流计算的新方法——单位累积过程线法。详细阐述了该方法定义、假定和分析方法,采用迭代法分析得到漳河水库流域单位累积过程线,建立了单位累积过程线与流域暴雨中心位置和降雨强度的相关关系,实现了由已知暴雨中心位置和降雨强度反推流域单位累积过程线,对所分析的单位线进行公式化,并运用到生产实践中。
According to the actual situation of Zhanghe River Basin flood, puts forward a new method for computation of watershed flow concentration unit cumulative process line method, a detailed ex-planation of the method definition, assumptions and analysis method, an iterative method is adopted to analysis of Zhanghe reservoir watershed unit cumulative process line, the relationship between the unit accumulative process line and the rainstorm center position and rainfall intensity, achieved by known center of rainstorm and rainfall intensity backstepping watershed unit cumulative process line, of formula on unit hydrograph analysis out, and used in production practice.
