Error when running WRF-Hydro ArcGIS Preprocessor

[Feyera A. Hirpa]

Hello,

I am attempting to prepare the routing files for WRF-Hydro. However, I keep on getting the following error (shown in red where it failed). The arcpy appears to fail to project the elevation raster to WRF format. Can anybody please help me fix it?

Thank you very much.

Best,

Feyera

Feyera,

I see that you are using ArcGIS Desktop v10.9.1 (or 10.8 depending on where I am looking for the version information). Do you have the 64-bit background geoprocessing installed and active? You only sent part of the log file, so I can't tell. In any case, you are trying to reproject a raster of size (73991, 44069) to a grid of size (7990, 4490). This is a very memory intensive operation. I think you ran out of memory, which is usually why the ERROR 999999 happens. Can you clip the input DEM down in size or use one with a resolution closer to your target resolution of 100m? Do you have ArcGIS Pro available to you, which is 64-bit and can handle much larger datasets? I think the issue will be in reducing the memory requirement of the application. You could alternatively use the open-source WRF-Hydro GIS Pre-processor, which may have a lower memory requirement than ArcGIS.

Thanks,

Kevin
