Non-dispersive conservative regularisation of nonlinear shallow water (and isentropic Euler equations)

D Clamond, D Dutykh - … in Nonlinear Science and Numerical Simulation, 2018 - Elsevier
A new regularisation of the shallow water (and isentropic Euler) equations is proposed. The
regularised equations are non-dissipative, non-dispersive and posses a variational …
