Hi, I am currently working on a research project involving aquifer depletion and pumping rates as they pertain to a cone of depression, flow rates, and ultimately 'death' of the aquifer. I went through the tutorials for AHGW and found the program to work nicely, except there is no simulations involved. The AHGW model allows you to build geovolumes and cross-sections based on borehole data, (which is good), but how about the next step, simulating the world's demise in aquifer depletion. If there is any other software out there for aquifer simulation I would like to know. As for AHGW, I will keep modeling, but hopefully in the near future they can add some more functionality to these models.
