Hi, I am using Arc Hydro tool. I tried to find the geometry of wetlands of a raster data (DEM) using "depression evaluation". It shows me spatial reference has missing z unit. I saw many solutions in google but not sure which should I try. Should I edit the .prj file to change the value of unit in meter by placing 100 instead of 1 ?

You don't want to edit the .prj file. You may have to change the format or location of the file or refer to this post: to https://community.esri.com/thread/102812. What is the exact error you're getting? If it has to do with Z values/units, then you may have to adjust the attribute table or your coordinate system.
