title: Yudovitch theorem for the lake equation

abstract: 
The lake equation  reads $\partial_t  (b u)  +  div ( b u \otimes u) + \nabla p = 0$, 
$div ( b u ) = 0$ on a  2-D domain and $(b u) \cdot n = 0$ on the boundary. 
The function $b(x) > 0$ represents the topography of the bottom. When $b$ 
is constant, this is the standard incompressible 2-D Euler system.
We extend Yudovitch theorem to cases where $b$ vanishes on the boundary.
