Modelling Well Transmissivity

Is there anyway to model groundwater well transmissivity?

 i.e. the more flow you pull from a reservoir, the lower the HGL of said reservoir.

The only pattern I can seem to apply to reservoirs is a time-based one, which is only applicable in EPS. It seems to me that there should be a way to model transmissivity for steady state solution runs based on well (or 'reservoir) discharge.

  • There isn't a 'groundwater well' element where you could specify that, but it is possible to allow for well drawdown by adjusting the well pump's curve.

    There is a useful description of how to do this in the Help of most versions of WaterCAD/WaterGEMS. Search for a topic called "Modeling a Pumped Groundwater Well ".
