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
The Gravity Waves Time Step tool dialog has the following options:
- Input dataset
- Gravity
- Use courant number
- Gravity waves time step dataset
