The paper shows that a Finite Volume method with an HLL Riemann solver may incorrectly reproduce the depth-averaged velocity under uniform flow in a channel with non-rectangular cross section. A specific treatment for evaluating the fluxes at the sides has been proposed and tested.

Abstract
The paper shows that a Finite Volume method with an HLL Riemann solver may incorrectly reproduce the depth-averaged velocity under uniform flow in a channel with non-rectangular cross section. A specific treatment for evaluating the fluxes at the sides has been proposed and tested.File in questo prodotto:
