Technical Framework and Key Issues of Integrated Countermeasures Against Pluvial Flooding in Inland Cities of China

Abstract

Global climate changes and urbanization affect the hydrologic cycle in the city by increasing the probability of extreme precipitation events and further intensifying the frequency and intensity of urban pluvial flooding disasters. Based on the mechanism of urban hydrological cycle and impact factors of urban pluvial flooding, integrated countermeasures are given on three different levels by incorporating urban land use planning, urban flood control project, disaster management, hereby developing a " rational planning, multiple measures, scientific management" comprehensive response system. The key tasks including dispatching real-time floods, revising urban drainage standard and optimizing the projects of drainage and storage are discussed. The technical framework is introduced and the key issues are further discussed.
