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).
