Abstract
Low lying coastal cities are under high risk of the compound flood with frequent storm surge occurrence and sea-level rise. This study attempted to develop a hybrid modeling framework to simulate various physical process of the compound flood. In this regard, first, the storm surge process is simulated using a wave-flow coupled model ie, Delft3D-FLOW and simulated wave nearshore (SWAN). The meteorological forcing for the hydrodynamic model has been done by integrating a parametric Holland cyclone model in this framework. The urban flood process in compound flood is also simulated using a rainfall-runoff model, the storm water management model (SWMM). The case study to evaluate the performance of the modeling framework is selected as the northern Bay of Bengal and extends to surge affected areas of Chittagong coast of Bangladesh. The modeling system is employed to simulate compound flood …
