Flood Emergency Management Using Hydrodynamic Modelling
In order to reduce the potential hazard of life and property loss, research on the flood emergency management is very important. A flood impact assessing methodology was proposed and examined in Qingshan reservoir. The key technologies include the flood routing simulation based on 2D hydrodynamic model, and flood losses assessment based on GIS cell. The 2D hydrodynamic model can quickly calculate flood submerged area, flood water depth distribution and flood routing time. The flood information could improve efficiency of flood emergency management and could offer more help in risk indications. The research results provide a powerful tool to analyze flood risk rapidly and make schemes for the flood resisting.
Tool development and case study
Locating in middle and lower reaches of South Shaoxi Brook, Qingshan is a large (2) type reservoir for flood control mainly, with purpose of irrigation, power generation and others. Qingshan Reservoir plays a significant role to protect safety of Datang, the dangerous place in the west of Hangzhou City.
