Mountain-Lake Model
Consider the following site:

Build a simple groundwater model representing this system. Input is from recharge. Parallel flow boundaries on the top and bottom.
- Build grid
- X, length = 20000, 100 cells
- Y, length = 15000, 75 cells
- Z, length = 500, 1 cell
- Properties
- Top = 3200, bottom = 2700
- K = 2 ft/day
- Recharge
- 20 inches of rain per year
- 15% reaches aquifer
- Lake
- Specified head
- Elevation = 3000
- Save and run model
- Add a well
- Permitted at 10 AFA (acre-ft/year)
- Explore
- Pumping rate (bigger)
- More wells
- K value
- Recharge
