摘要
采用室内模拟降雨试验,对各种城市地面,如土地面、草地、混凝土地面及其多种组合的产流特性作了系统试验,分析了降雨强度与历时、土壤湿度与密实度、地面覆盖、不透水面积比例与位置等因素对径流系数和产流过程的影响,为城市水文规律的研究和模拟计算提供了可靠依据.
Based on simulating rainfall experiment in laboratory, the characters of runoff yield of some urban surfaces, such as soil, grass, concrete slope and their combination are systematically tested.Factors affecting runoff coefficient and hydrograph of urban surface, such as intensity and duration of rainfall, humidity and density of soil, land cover, position and proportion of impervious area are analyzed.These results provide the reliable basis for the analysis and simulation of urban rainfall runoff.
