Based on the properties of the terrain, water may infiltrate into the ground water system.
The speed at which water can infiltrate from the surface to the unsaturated zone is dependent on both the GROUND_INFILTRATION_MD of the surface terrain, as well as the GROUND_INFILTRATION_MD of any building in that location, if present. Of the infiltration values of the building and the surface terrain, the lowest value is used. If either has an infiltration value of 0, water cannot infiltrate into the unsaturated zone.
The maximum amount of water which can be stored in the saturated zone is based on the WATER_STORAGE_PERCENTAGE of the ground terrain.
Ground flow, or horizontal infiltration, are dependent on the infiltration properties of the ground, unless an aquifer exists at the same location.
Notes
- The groundwater level reduction is inversely proportional to the WATER_STORAGE_PERCENTAGE, as the contribution of a given volume of water to the groundwater level increases when the capacity for water storage in the ground layer decreases.
