+To let the manhole exchange with groundwater, specify the *Exchange thickness*, *Hydraulic conductivity in*, and *Hydraulic conductivity out*. This is independent from the calculation type (embedded/isolated/connected), so you can also schematise a manhole that does *not* exchange with the surface water domain (calculation type is isolated), but *does* exchange with the groundwater domain.
