Shallow Water Model for Lakes with Navier slip boundary condition

Abstract

We study a model describing the motion of the fluid in a lake, assuming inflow-outflow effects across the bottom, the porous coast and the inflows and outflows of rivers. We prove the global in time existence result for this model. The solvability is shown in the class of solutions with $L_{p}$-bounded vorticity for any given $p\in (1,\infty]$.
