- Abstract:
- The study of rain patterns is the basis of modern urban storm management. Different rain patterns have different runoff calculation results, which have a great impact on the design and operation of initial rainwater storage facilities. Based on extensive rainfall data measured in a combined drainage system in Shanghai downtown area, a representative rainfall process was selected as the design rain pattern sample. A quantitative expression method of rainfall-runoff and a short-duration design rain pattern suitable for initial rainwater interception in Shanghai were proposed. These methods are helpful to determine the inflow and regulation volume of rainwater storage facilities, and provide important reference values for the design, regulation, and operation of such facilities.
