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.

We are using SRH-2D to model a proposed channel cut in a river. The inlet boundary condition we're using is a variable flow rate with positive and negative values as we have a tidal flow condition. When I run the model, I receive the error shown below. It seems like the negative flow rates are the source of the error. Does anyone know how to allow for negative flow rates in SRH-2D?
