I am trying to reconditioning a raster (flow accumulation) using "DEM Reconditioning". However it keeps showing the following error ( details are attached)
"System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component.
at ESRI.ArcGIS.Geoprocessing.GeoProcessorClass.Execute(String Name, IVariantArray ipValues, ITrackCancel pTrackCancel)
My procedure is
Sink Evaluation > Flow Direction > Flow Accumulation > Fill sink > Flow Direction > Flow Accumulation > DEM Reconditioning
I have tried all the options described in this blog. Any suggestion will be highly appreciated.
Mirza,
You should do the DEM Reconditioning first. Then do fill sinks. Then do flow direction. Basically the order of operation is the order the tools appear in the menu. You don't have to use all of the tools.
The HRESULT error could be due to having the project an Arc Hydro file on a network server. Move the project to your PC and try it.
Search for the "Arc Hydro Problem Solvers" thread. I created that thread and there are lots of practical suggestions there.

Hi Mark, I have tried to run DEM RECONDITIONING, I have tried all the solutions posted here, but I couldn't run the tool. I'm using ArcGIS 10.7, windows 10. The process starts, but I have noticed in Results that after the "Eculidean Allocations", the process "IsNull" can't be completed, as follows:
