【摘要】：以郑州海绵城市雨水资源作为研究方向,探讨雨水径流系数对雨水利用方面的影响程度。首先,给出径流系数概念,根据降雨与径流的关系获知影响径流系数的主要因素为降雨、产流及汇流,同时利用上述关系可将径流系数具体区分为雨量径流系数及流量径流系数,其中前者包括瞬时雨量径流系数、场次雨量径流系数和年平均雨量径流系数,后者包括瞬时流量系数和峰流量径流系数,为雨水控制利用系统提供理论支持;其次,采用极限强度法对降雨初期弃流雨水量进行分析,提出雨水储存池容积计算法,对集水量、用水量等各种水量进行计算,从而达到雨水水量利用平衡的效果。实验表明,利用径流系数可为雨水控制利用系统提供数据基础。
[Abstract]:Taking Rain Water resources in the sponge city of Zhengzhou as the research direction, the paper discusses the influence degree of Rain Water runoff coefficient on the utilization of Rain Water. First, the concept of runoff coefficient is given. According to the relationship between rainfall and runoff, the main factors affecting runoff coefficient are rainfall, runoff generation and runoff confluence, and the runoff coefficient can be divided into rainfall runoff coefficient and discharge runoff coefficient. The former includes instantaneous rainfall runoff coefficient, field rainfall runoff coefficient and annual average rainfall runoff coefficient, the latter includes instantaneous flow coefficient and peak runoff coefficient, which provides theoretical support for Rain Water control and utilization system. The limit intensity method is used to analyze the amount of water that is abandoned at the beginning of rainfall. The volume calculation method of Rain Water storage pool is put forward to calculate the amount of water collected and used, so as to achieve the effect of the water use balance of Rain Water. Using runoff coefficient can provide data basis for Rain Water control and utilization system.
