Abstract:

We prove the convergence of the hydrostatic reconstruction scheme with kinetic numerical flux for the Saint Venant system with continuous topography with locally integrable derivative. We use a recently derived fully discrete sharp entropy inequality with dissipation, that enables us to establish an estimate in the inverse of the square root of the space increment $\Delta x$ of the $L^2$ norm of the gradient of approximate solutions. By DiPerna’s method we conclude the strong convergence towards bounded weak entropy solutions.
