Notes
- This minimal fraction prevents the unsaturated zone from running dry. Default value is around the 10%.
- Water either comes from above (surface) or uptake from below (saturated zone) to reach this value.
- When the ground water (saturated zone) drops below the GROUND_WATER_MAX_UPTAKE_DEPTH_M this uptake is stopped.
- Can also be adjusted via a Min unsaturated fraction prequel (Water Overlay).
