    Hi, I'm using SRH to model tidal inundation from a river into a wetland. The wetland is only connected to the river by 1 large culvert. In the SRH model, can a single culvert model flow in both directions? I seem to get flow into the wetland (which is the direction of flow according to the nodestring pair order). However as the water level drops on the upstream side of the culvert, the downstream side stays relatively level (as if the water doesn't flow back in the other direction). If a culvert does only work for one direction, does anyone have recommendations on how simulate flow in both directions? Maybe use two culverts, side by side? Thanks in advance! Any advice is greatly appreciated.

    Has anyone had any experience modeling culverts into CMS-Flow? I am trying to simulate marsh site in southern new jersey that in piped within its main channel inlet for a small bridge crossing. I have pulled in a code to match the descriptions for coding culverts as outlined in the bulletin from USACE, found here http://acwc.sdp.sirsi.net/client/search/asset/1029144 , for my specific site. The model will run up to the point flow begins to enter into the pipe, and then crashes and states the model is divergent. Does anyone have any experience or tips on how to check and resolve the issues causing the model to crash with the culvert code?
