A well balanced scheme for the shallow water wave equations in open channels with (discontinuous) varying width and bed

Roberts, Stephen; Wilson, Padarn


Finite volume methods have proven themselves a powerful tool for finding solutions to the shallow water wave equations. They are based on the conservation laws for the mass and momentum, integrated over discrete finite volumes. These methods tend to do well at the diffcult problem of capturing solutions involving shocks. However, one area that causes problems is the approximation of steady or near steady states when there is a sloping bed elevation. The problem arises due to a poor balance...[Show more]
