Hi all!

I would like to ask your help.

I am working on the Hydrological modelling using HEC-HMS, with the ERA5-Land dataset for a basin in south of France

In particular, I downloaded the ERA5-Land precipitation data from Copernicus Climate Change Service relative to my basin in Netcdf/Grib format.

My questions are:

- Can I import my subset gridded data in HEC-HMS?

I tried to import the gridded data (File -> Import -> Gridded data) - 4 files in .nc format for a historical flood 1978, the variable is total precipitation - to convert NetCDF files in .dss format. In my case, I created the destination file called “Era5Land.dss”.

At the end of the importing, the file Era5Land.dss is empty, it doesn’t contains the converted data.

(I use HEC-HMS v4.10 )

Thank you!
