  1. Hi all, I have a quick query regarding processing grid files using ArcGIS. We use XP-SWMM here, and can export an Asc results file which can then be imported to ArcGIS. For a flood envelope depth map which I have created in ArcGIS, the majority of it looks fine, however, some areas of lower depths around the edges of the extents have some wet areas missing. Approx 95% of the results match to the results shown in XP-SWMM. Why is this? I am using a 20m cell, and know that ArcGIS is using a 10m grid. Also, the grid network is orientated NW to SE, while the ArcGIS orientation is N to S. Any ideas?
