DRNAREA
The total drainage area (mi2) for a stream or river basin is measured in a horizontal plane enclosed by the drainage divide outlining the basin. Drainage areas for this report were measured in USGS StreamStats (http://water.usgs.gov/osw/streamstats/indiana.html).

K1Average hydraulic conductivity (ft/d) for the top 70 ft of unconsolidated deposits below land surface. It is a characteristic based on textural descriptions from water well driller logs obtained from state well log databases. Indiana Department of Natural Resources, Division of Water digital well database (http://www.in.gov/dnr/water/3595.htm). The values were converted into a statewide grid. Characteristic was calculated using method described in this report, as modified from Arihood (2009).
