Dear evreyone I tried to import a time series of netcdf files containing precipitation grid data in HEC-HMS by converting netcdf file to .dss file. I have followed the tutorial in the link below: https://www.hec.usace.army.mil/confluence/hmsdocs/hmsguides/creating-gridded-boundary-conditions-for-hec-hms When I read the .dss file in HEC-DSSVue v3. I get the following message : there are no records in the hec dss file. I'll be glad if you can help me to resolve this problem.
