1-D Numerical Simulation of Morphodynamic Processes under Dam Break and Overtopping flows
Publication: World Environmental and Water Resource Congress 2006: Examining the Confluence of Environmental and Water Concerns
Abstract
A 1-D finite-volume model has been established to simulate the morphodynamic processes under dam-break and overtopping flows over movable beds. The effects of sediment transport and bed change on the flow are considered in the flow continuity and momentum equations. An explicit algorithm is adopted to solve the governing equations. The model has been tested against an experiment on dam surface erosion due to overtopping flow and two experiments on dam-break flow over movable beds. The model performs quite well in the case of overtopping flow, but significantly under-predicts the bed erosion due to dam-break flow. A modification has thus been made by considering the effects of sediment concentration on sediment settling and entrainment. The modified model predicts the bed erosion under dam-break flow with much improved accuracy.
