https://community.esri.com/t5/water-resources-questions/archydro-create-sink-structures-takes-forever/m-p/1140820#M4163 <P>Hello,</P><P>I'm trying to run the Create Sink Structures from ArcHydro tools in ArcMap 10.6.1 (upgrade is not an option). Whatever the size of the raster (I tried 3 Go, then cropped it to 37 Mo and now 1 Mo), the script just keeps running and then ArcMap falls into "not responding" mode. I tried working with .tif and gdb raster. I'm using a Nad83 CSRS MTM&nbsp; projection for all the inputs. I have 8 Go ram, i5 core and SSD disk with 70 Go space left.&nbsp;</P><P>I don't understand what's happening. Has anyone experienced similar issue and found a work around?</P><P>Cheers,</P> Fri, 04 Feb 2022 16:44:27 GMT Anne-MarieDubois 2022-02-04T16:44:27Z https://community.esri.com/t5/water-resources-questions/archydro-create-sink-structures-takes-forever/m-p/1140820#M4163 <P>Hello,</P><P>I'm trying to run the Create Sink Structures from ArcHydro tools in ArcMap 10.6.1 (upgrade is not an option).
