Error Hydrological component relation with Ocean (GIS)

[jordi palacios]

Dear all, I'm trying to run WRF Hydro but Im facing some problems with the DEM product because there are some interferences related to the ocean in the whole domain ( The ocean shouldn't be in model).

For example, Flow Direction

Flow Accumulation

 Does anyone know how to solve this problem?

Best,

[Kevin]

Jordi,

You can avoid these artifacts if you set all ocean elevation values to NoData before using the GIS pre-processor. Typically, sea-level will be 0 in a DEM, and you can set 0 values to NoData using GIS tools such as ArcGIS, QGIS, or GDAL. 

Cheers,

Kevin
