WebApr 29, 2024 · An example of an Internal Boundary Stage and Flow Hydrograph (from the HEC-RAS User’s Manual) is shown above. In this example, HEC-RAS forces the stage to be 108 feet until the simulation begins. Then the program starts using the flow rates entered for the first two hours. After the first two hours, there is no more data entered, so the ...
