The Aquifer Editor is used when creating or editing an Aquifer object. It includes various data fields:

• Name: A user-assigned name for the aquifer.
• Porosity: The volume of voids compared to the total soil volume (as a volumetric fraction).
• Wilting Point: Soil moisture content at which plants can’t survive (volumetric fraction).
• Field Capacity: Soil moisture content after free water has drained off (volumetric fraction).
• Conductivity: Soil’s saturated hydraulic conductivity (in/hr or mm/hr).
• Conductivity Slope: Average slope of log(conductivity) vs. soil moisture deficit curve (unitless).
• Tension Slope: Average slope of soil tension vs. soil moisture content curve (inches or mm).
• Upper Evaporation Fraction: Fraction of total evaporation available for evapotranspiration in the upper unsaturated zone.
• Lower Evaporation Depth: Maximum depth below the surface for evapotranspiration from the lower saturated zone (ft or m).
• Lower Groundwater Loss Rate: Rate of percolation to deep groundwater when the water table reaches the ground surface (in/hr or mm/hr).
• *Bottom Elevation:*Elevation of the aquifer’s bottom (ft or m).
• Water Table Elevation: Elevation of the water table in the aquifer at the simulation’s start (ft or m).
• Unsaturated Zone Moisture: Moisture content of the unsaturated upper zone of the aquifer at the simulation’s start (volumetric fraction, not exceeding soil porosity).
• Upper Evaporation Pattern: The name of a monthly time pattern used to adjust the Upper Evaporation Fraction for different months of the year (leave blank if not applicable).
