Getting the depth of the water is a little tricky. As your geometry is quite simple you can probably do it as an analytical function versus X position. Drawing the depth is likely to be beyond CFD-Post so I would export this data (File/export) and use something like matlab/python/whatever to process the data and determine the water depth. hamidciv likes this.
