基于SWMM的信陽市小區(qū)水量平衡分析及研究
[Abstract]:The real time rainfall data in Xinyang area are calculated and analyzed. According to the basic situation of Rain Water's utilization in Xinyang residential district, the effect of production and confluence of Fengping dry typical level year is considered synthetically. Based on the SWMM rainstorm runoff model, this paper generalizes the different underlying surfaces of the residential area, considers the influence of surface infiltration and the water quality of the catchment water, and puts forward a method to determine the available water quantity. According to different Rain Water collection, the rational allocation of water resources was studied. In theory, combined with the basic theory of urban and water resource utilization and runoff production and confluence, the method of calculating area rainfall distribution and the hydrodynamic model equation of slope runoff are adopted, and the water balance analysis is carried out by using the urban rain flood simulation software SWMM,. Allocation of a reasonable use of Rain Water program. Firstly, the engineering investigation is carried out, the simulation area is determined, and the basic data are collected, including meteorological data, underlying surface data and official website data. The urban rain flood simulation model is constructed, the operation parameters of the model are determined, and the rain flood simulation calculation in the modeling area is carried out through the measured rainfall data in the region. Combined with the SWMM software, the runoff yield and confluence analysis are carried out. Considering the effect of annual rainfall on runoff characteristics in Fengping in different periods, so as to calculate water collection, water consumption and water quality of Rain Water in three typical months of Feng, Ping and Kuo. This paper sets up various collection schemes of Rain Water and Rain Water, analyzes and compares the comprehensive benefits of different schemes, and studies and summarizes the optimal planning and optimal treatment of the collection scheme of Rain Water in the residential area.
