[@ziadabdeldayem6884]

@@fekadugemeda2707You need to extract the zipped folder. If you have done that and still have the issue, try to download your data again.

Is this DEM workable in HEC-HMS ? Or need for any process before exporting to HEC-HMS? “Note: I download from same site but unfortunately couldn’t define terrain date in HEC-HMS by using this DEM, so any advice ?

[@ziadabdeldayem6884]

I have not delt with HECHMS before. You may need to check (and change) the DEM format that works with HEC and also pay attention to the coordinate system.

I'm looking for 5meter DEM or less paid or not where can i find?

[@ziadabdeldayem6884]

It depends on the country you're in. I think Lidar data would be good for your needs.

Does this model need to fill?

[@ziadabdeldayem6884]

Hi Aya. I have not checked that. But if it requires filling, you can interpolate to estimate the missing values.
