Outlet Drop Criteria for Entering the Culvert


The outlet drop is the difference between the water surface elevation in the culvert outlet and the tailwater elevation.  If the Outlet Criteria on the Fish Information section of the Input Window is set to Max Outlet Drop, FishXing compares the calculated outlet drop to the user specified Max Outlet Drop.  If the Outlet Drop is greater than the Max Outlet Drop, FishXing identifies an “Outlet Drop Barrier” at that specific flow.
