Patent ID: 11868690

Abstract:
A method for analyzing disaster prevention and mitigation effectiveness of an ecological seawall is provided, including: performing seawall ecologicalization on a target seawall; establishing three-dimensional space hydrodynamic force for the target ecological seawall; simulating wave climbing on a dike body and a wave overtopping on a dike top of the target ecological seawall to obtain a wave overtopping index; calculating wave-flow bottom shear stress of the target ecological seawall, establishing a sediment movement model, and calculating suspended load and bed load sediment transportation volumes; calculating the change index of coastal bed surface according to the suspended load and bed load sediment transportation volumes, and determining a development index of tidal flats in front of dike of the target ecological seawall according to the change index; and calculating the disaster prevention and mitigation effectiveness grade of the target ecological seawall according to the wave overtopping index and the development index.
