#  This directory contains items relating to the numerical solution 
#  of the shallow water equations in spherical geometry.
#  The shallow water equations are used as a kernel for both
#  oceanic and atomospheric general circulation models and
#  are of interest in evaluating numerical methods for weather
#  forecasting and climate modeling.  The DOE Computer Hardware, 
#  Advanced Mathematics and Model Physics (CHAMMP) program 
#  is interested in the development of new mathematical methods
#  for these problems.  To promote this developmet, a set of 
#  test cases has been proposed and example software and reference
#  solutions are provided.
