Urban rainwater runoff regulation and control method based on LID measures
The invention discloses an urban rainwater runoff regulation and control method based on LID measures. The method comprises the steps that 1, a Lagrange interpolation method is used for obtaining a runoff coefficient before development; an LID control editing module in a rainstorm management model is utilized for obtaining the parameter value range of the LID measures; parameters of a surface layer, a pavement layer, a soil layer, a water storage layer and a closed conduit are adjusted according to design requirements; 2, sub-catchment areas are divided, a first-level catchment area with a main river as the center is formed, a second-level catchment area is divided according to a refined DEM graph, and a third-level catchment area is formed according to the distribution condition of drainage facility space; 3, hydrological process simulation is executed; and 4, hydraulic process simulation is executed.
本发明公开了一种基于LID措施的城市雨水径流调控方法，包括：步骤1：使用拉格朗日插值法获取开发前径流系数；利用暴雨管理模型中LID控制编辑模块，获取LID措施参数取值范围；再根据设计需要调整表面层、路面层、土壤层、蓄水层和暗渠的参数；步骤2：划分子汇水区域，形成以主干河流为中心的一级汇水区域，根据细化的DEM图划分二级汇水区；再根据排水设施空间的分布情况，形成三级汇水区域；步骤3：执行水文过程模拟；步骤4：执行水力过程模拟。
