- A negative value means passive drainage, fixing the groundwater level to the surface water level. A positive value means active drainage, keeping the ground water level at a specific height.
- Although the effect of drainage to subsidence are via an intermediate effect on groundwater, this value is not used in the Water Overlay. To model drainage in the Water Overlay, use an Aquifer instead.
