On weak solutions to the 2D Savage-Hutter model of the motion of a gravity driven avalanche flow

Eduard Feireisl, Piotr Gwiazda, Agnieszka Swierczewska-Gwiazda

We consider the Savage-Hutter system consisting of two-dimensional depth-integrated shallow water equations for the incompressible fluid with the Coulomb-type friction term. Using…
