- Description
- Loss evaluation of dike-break-induced flood disaster has become a worldwide concern due to its enormous economic, environmental, and societal importance. In this paper, the Sanjiao dike in the Poyang Lake district in China is investigated as a case study. An integrated dike-break-induced flood modeling and losses assessment framework is proposed. The MIKE 21-based numerical approach is developed to model the flood routing process in the flood protection region of dike. A flood routing model that can take into account the influence of land utilization on the roughness coefficient of underlying surface is established for the Sanjiao dike. By this means, the flood water depth, flow velocity, flood peak appearance time, and other spatiotemporally distributed flood inundation data can be obtained. With the behavior of the flood well understood, a physics-informed quantitative approach is further developed on ArcGIS and Python platform to assess the dike-break-induced flood losses, including life, economic, and ecological environment losses. The research outcomes provide an integrated decision-making process for flood warning and risk mitigation in the protection region of dike.
