I believe that the slope raster does not necessarily give this value but calculates slope from the maximum change in z-value. Is there another way to ensure that the slope along the stream is being given in the downstream direction?</SPAN></BODY></HTML> Wed, 08 Jan 2014 17:28:01 GMT https://community.esri.com/t5/water-resources-questions/determining-the-slope-along-a-stream/m-p/690868#M3558 ChristineWehner 2014-01-08T17:28:01Z Re: Determining the slope along a stream https://community.esri.com/t5/water-resources-questions/determining-the-slope-along-a-stream/m-p/690869#M3559 <HTML><HEAD></HEAD><BODY><SPAN>No, but you can use the 3D analyst and create a profile along the stream and calculate slope from there</SPAN></BODY></HTML> Wed, 08 Jan 2014 17:31:21 GMT https://community.esri.com/t5/water-resources-questions/determining-the-slope-along-a-stream/m-p/690869#M3559 DanPatterson_Retired 2014-01-08T17:31:21Z Re: Determining the slope along a stream https://community.esri.com/t5/water-resources-questions/determining-the-slope-along-a-stream/m-p/690870#M3560 <HTML><HEAD></HEAD><BODY><P>Hi Christine,</P><P></P><P>I am trying to do exactly that.
