Query: A class of boundary conditions for time-discrete Green-Naghdi equations
  with bathymetry   This work is devoted to the structure of the time-discrete Green-Naghdi
equations including bathymetry. We use the projection structure of the
equations to characterize homogeneous and inhomogeneous boundary conditions for
which the semi-discrete equations are well-posed. This structure allows us to
propose efficient and robust numerical treatment of the boundary conditions
that ensures entropy stability of the scheme by construction. Numerical
evidence is provided to illustrate that our approach is suitable for situations
of practical interest that are not covered by existing theory.
