中文摘要:
      江西省推理公式采用了五点折腰多边形过程线进行洪水过程概化,使得洪水的时间坐标与暴雨的时间相互独立,当需进行地区洪水组成计算时,由于各分区洪水的时间坐标各自独立,各分区洪水不能直接叠加,必须先统一时间坐标。本文根据推理公式法的雨洪关系,提出了一种根据洪峰产生时间将洪水时间坐标统一至暴雨时间坐标的简便方法,可供水文设计人员参考。
英文摘要:
      The reasoning formula,as widely used at home,is a simplified method of calculating storms and floods of small watersheds.The reasoning formula of Jiangxi Province applied five-point-bend and polygonal process line to generalize the forming process of floods,which makes the time coordinate and the time of rainstorms independent of one another.When calculating the composition of regional floods,because of the independent time coordinate of each regional flood,they cannot be directly added,but must first be unified.According to the relationship between rainfalls and floods of the reasoning formula,this paper put forward a simple method for the reference fo hydrological designers,which postualtes that the time coordinates of floods could be unified to those of rainfall in accordance with the time when flood peaks come.
