Has anyone performed a 2D tidal model? I’m working on a project where we have a bridge a few miles upstream of the Charleston, SC harbor and I’m trying to determine the 10, and 100-yr surge elevation at the bridge. I’m using a stage hydrograph at the downstream end where we have the harbor. I have gage data that I’m trying to use to calibrate my model. With my 2d model I’m unable to calibrate as close as i can with my 1D model. I have tried to change from Diffusion Wave to Momentum with no luck. Anyone performed any similar models with HECRAS 2D?
Thanks
