topic Error in Arc Hydro when running Flow Direction with Sinks in Water Resources Questions https://community.esri.com/t5/water-resources-questions/error-in-arc-hydro-when-running-flow-direction/m-p/89627#M379 <HTML><HEAD></HEAD><BODY><SPAN>Hello folks!</SPAN><BR /><BR /><SPAN>I am running the function "Flow Direction with Sinks" in Arc Hydro version 4, and I get the message you can see in the picture. I am working with ArcView 9.3.1. Spatial Analyst.</SPAN><BR /><BR /><SPAN>I ran the same function and same workflow about 3 months ago, without problems at all, so I do not understand what is the problem now. My setup is simple and it´s described in the picture called "Model", from Model Builder.</SPAN><BR /><BR /><SPAN>Basically I have a polygon layer called Depression (obtained with the Depression function in Arc Hydro) and a filled terrain model (FilDepr), both of which I use as input in the function. Out of the 4 resulting files, there is only one which is created successfully: the point layer (DeprPoint).</SPAN><BR /><BR /><SPAN>I have tried to run the function both using my model, and also directly from the Arc Hydro tool bar, but nothing works. Anybody can give me a hand on this? Please!</SPAN><BR /><BR /><SPAN>Kind regards,</SPAN><BR /><SPAN>Alvaro</SPAN></BODY></HTML> Mon, 07 Feb 2011 07:57:05 GMT AlvaroFonseca 2011-02-07T07:57:05Z Error in Arc Hydro when running Flow Direction with Sinks https://community.esri.com/t5/water-resources-questions/error-in-arc-hydro-when-running-flow-direction/m-p/89627#M379 <HTML><HEAD></HEAD><BODY><SPAN>Hello folks!</SPAN><BR /><BR /><SPAN>I am running the function "Flow Direction with Sinks" in Arc Hydro version 4, and I get the message you can see in the picture.
