Modelling dam-break flows over mobile beds using a 2D coupled approach

J Xia, B Lin, RA Falconer, G Wang - Advances in Water Resources, 2010 - Elsevier
Dam-break flows usually propagate along rivers and floodplains, where the processes of
fluid flow, sediment transport and bed evolution are closely linked. However, the majority of …
