Model Input Parameter	Description of Parameter	Mound Height	Mound Extent	Effect on Groundwater Mounding
Horizontal Hydraulic Conductivity of Aquifer	Measure of resistance to flow of water through a unit volume of aquifer matrix in the horizontal direction. Table 12 of USGS Paper 1839-D provides a summary of mean horizontal permeability by predominant particle size. Typically assumed to be greater than vertical hydraulic conductivity by a 10:1 ratio.	Decreases as hydraulic conductivity increases	Increase as hydraulic conductivity increases	Increasing horizontal hydraulic conductivity allows for greater ability to transmit water away from the source of infiltration. This allows for lower height of groundwater mounding, but greater extents.
