Abstract

Urban flood risk assessment supported by accurate and precise modeling could make great contributions to urban flood management. In this paper, an urban drainage system model of Shijiazhuang city was built based on the MIKE21, MIKE URBAN and MIKE 11 modules in MIKE FLOOD platform in order to provide a storm sewer drainage capacity and waterlogging risk evaluation. The results show that in Shijiazhuang, 64.5% of storm sewer drainage criteria is less than 1-year return period storm, and only 28.9% of storm sewer can meet the drainage criteria of 2-year return period storm. The waterlogging risk area grows from 3.2, 15.1 to 18.5 square kilometer when the return period is 10, 20 and 50 years. Both the current condition and the drainage system model database indicate the reasons of the drainage issue in Shijiazhuang which can be summarized as the rapid urbanization, the low capacity of pipe network and pumping stations, the low construction standard, the lag between the sewer system construction and the demand, the lack of drainage outlet, and the imperfect management system.
