 Bottom boundary condition of the horizontal velocity components u and v.\\\\
-Allowed values are '' 'dirichlet' '' and '' 'neumann' ''. '''bc_uv_b''' = '' 'dirichlet' '' yields the no-slip condition with u=v=0 at the bottom. Due to the staggered grid u(k=0) and v(k=0) are located at z = - 0,5 * [#dz dz] (below the bottom), while u(k=1) and v(k=1) are located at z = +0,5 * dz. u=v=0 at the bottom is guaranteed using mirror boundary condition:

-      u(k=0) = - u(k=1) and v(k=0) = - v(k=1)

+Allowed values are '' 'dirichlet' '' and '' 'neumann' ''. '''bc_uv_b''' = '' 'dirichlet' '' yields the no-slip condition with u=v=0 at the bottom. 
 The Neumann boundary condition yields the free-slip condition with u(k=0) = u(k=1) and v(k=0) = v(k=1). With Prandtl - layer switched on (see [#prandtl_layer prandtl_layer]), the free-slip condition is not allowed (otherwise the run will be terminated).
