Gravity Waves Time Step
The toolbox includes a tool for calculating the time step given the Courant number.
Note: the variable here is depth, not elevation. For applications relative to mean sea level, using the negative of the elevation relative to a datum is acceptable, but if the water level will vary, the depth is actually the water level minus the ground elevation
