Template:Gravity Waves Courant Number

Gravity Waves Courant Number

The toolbox includes a tool for calculating the Courant number given the time step.

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.

${\displaystyle CourantNumber=TimeStep*(Gravity*Depth)^{0.5}/NodalSpacing}$
