Hello! I'm trying to create my flood simulation. I imported my data from ArcGis to Hec-Ras, did all the steps and brought my computation in ArcGis again to visualize the flood. I managed to do the "Water surface generation", without problem, but I got stuck in the "Floodplain delineation Using Rasters", where errors appears (photo attached).
I looked for solutions online, but I didn't find anything. I'm not an expert of the programs at all and I don't know how to solve the issue. Anybody has any idea?
Thank you in advance.
