Hi Group;
I am fairly new to GV and updating an existing model with new site data. Thus
far, I have been able to update the layer elevation, well and target points by
importing site specific data in surfer grid file, or XYZ coordinates. However,
I am unable to import the GHB BCs, specifically, the head value. I am grounping
my GHBs in 3 reaches, and updating them with new grid files is causing much
headaches. Tried simplified by specifying the reach I want to edit, but when I
import the grid file the GHB is not updated.

I am using GV 5.0, any help/insight will be appreciated.

Thanks
Lansana
