Query: Planar hydraulic jumps in thin films: a regular solution against
  experiments   The formation of a planar hydraulic jump has been analysed in the framework
of a full depth-averaged thin film model (DAM) with surface tension effects
included. We have demonstrated regular weak solutions of the full DAM and
analysed surface tension effects. It has been shown that surface tension
effects within the parameter range relevant to the recent experiments are
expected to be very weak and practically negligible. The developed methodology
can be used in the analysis of laminar flow regimes and as a benchmark in
developing full scale hydrodynamic models.
