+the shallow water equations on structured grids.  The name FullSWOF
+refers to the Full form of the Shallow Water equations for Overland
+Flow.  The discretized system of equations is solved using the finite
+volume method.  A choice of shock-capturing methods is available to
+locate the transition boundaries between the wet areas and the dry
+areas in the model.  A semi-implicit method is used to advance the
+solution in time.  The tool is typically applied to the modelling of
+river flooding.")
