Abstract EN
The last two decades have seen great progress in mathematical modeling of fluvial processes and flooding in terms of either approximation of the physical processes or dealing with the numerical difficulties.
Yet attention to simultaneously taking advancements of both aspects is rarely paid.
Here a well-balanced and fully coupled noncapacity model is presented of dam-break flooding over erodible beds.
The governing equations are based on the complete mass and momentum conservation laws, implying fully coupled interactions between the dam-break flow and sediment transport.
A well-balanced Godunov-type finite volume method is used to solve the governing equations, facilitating satisfactory representation of the complex flow phenomena.
The well-balanced property is attained by using the divergence form of matrix related to the static force for the bottom slope source term.
Existing classical tests, including idealized dam-break flooding over irregular topography and experimental dam-break flooding with/without sediment transport, are numerically simulated, showing a satisfactory quantitative performance of this model.
