| Abstract: | We consider the inviscid limit of the two-dimensional viscous lake equations when the Navier slip conditions are prescribed on the impermeable boundaries of the general regular domains.Our results show that the boundary layer of the viscous lake equations with Navier boundary is always nonlinearly stable in some Sobolev spaces and we justify an asymptotic expansion which involves a weak amplitude boundary layer,with the same thickness as in asymptotic theory and a linear behavior. |
| Keywords: | viscous lake equations Navier boundary conditions lake equations vanishing viscosity limit |
