A robust and novel procedure is introduced into a fixed-grid finite volume shallow-water model to consistently track fluid volume and the free surface elevation in partially submerged triangular cells, which leads to excellent flow and scalar transport predictions in the presence of a stationary or moving wet/dry interface. Using this procedure, a Roe-type finite volume scheme is found to perfectly conserve both fluid and dissolved mass, preserve stationarity, and nearly eliminate artificial concentration and dilution of scalars at wet/dry interfaces.

Abstract

A robust and novel procedure is introduced into a fixed-grid finite volume shallow-water model to consistently track fluid volume and the free surface elevation in partially submerged triangular cells, which leads to excellent flow and scalar transport predictions in the presence of a stationary or moving wet/dry interface. Using this procedure, a Roe-type finite volume scheme is found to perfectly conserve both fluid and dissolved mass, preserve stationarity, and nearly eliminate artificial concentration and dilution of scalars at wet/dry interfaces.
