topic Find water surface elevation from introducing a known volume of water at a point in Renewable Energy Questions https://community.esri.com/t5/renewable-energy-questions/find-water-surface-elevation-from-introducing-a/m-p/542078#M136 <HTML><HEAD></HEAD><BODY><P>I am trying to find the water surface elevation that results from a certain volume of water being introduced into an area from a point. I can use surface volume (BELOW) for this while iterating over elevations until I achieve a matching volume, but I want to apply this volume of water only to areas that are continuously connected to the point source. Basically, I need one pool, not multiple. </P><P></P><P>I was considering chopping my DEM to only include the single "pool", but because I don't know the elevation yet, this is somewhat difficult. </P><P></P><P>Is there an easier or simple way to achieve this?</P><P></P><P>I am using LIDAR data to produce a DEM and have access to 3d analyst, spatial analyst, and the hydrology toolset. </P></BODY></HTML> Mon, 04 Aug 2014 04:59:17 GMT RyanDunne 2014-08-04T04:59:17Z Find water surface elevation from introducing a known volume of water at a point https://community.esri.com/t5/renewable-energy-questions/find-water-surface-elevation-from-introducing-a/m-p/542078#M136 <HTML><HEAD></HEAD><BODY><P>I am trying to find the water surface elevation that results from a certain volume of water being introduced into an area from a point.

Once you have the basin polygon, you can incrementally flood it until your volumes match. Alternatively, if you download the Arc Hydro extension, there is a tool called Drainage Area Characterization that does this for you:</P><P></P><P><A href="http://downloads.esri.com/archydro/archydro/Setup/" title="http://downloads.esri.com/archydro/archydro/Setup/">http://downloads.esri.com/archydro/archydro/Setup/</A>‌</P></BODY></HTML> Mon, 04 Aug 2014 20:42:22 GMT https://community.esri.com/t5/renewable-energy-questions/find-water-surface-elevation-from-introducing-a/m-p/542080#M138 DanielSiegel 2014-08-04T20:42:22Z
