On the best quantity reconstructions for a well balanced finite volume method used to solve the shallow water wave equations with a wet/dry interface

Mungkasi, Sudi; Roberts, Stephen

Description

Well balanced finite volume methods used to solve the shallow water wave equations are designed to preserve the steady state of a 'lake at rest'. Unfortunately, for problems involving wet/dry interfaces, this steady state is not preserved unless the involved quantities are reconstructed with care. We test four reconstruction options: stage and momentum (where bed is fixed); stage and velocity (where bed is fixed); stage, water height, and velocity; and stage, bed, and velocity (with...[Show more]
