Hydraulic conductivity measurements using a Purdue sprinkling infiltrometer were performed on plots with the resultant data of cumulative runoff vs. time analyzed to determine values of hydraulic conductivity through the use of a cumulative runoff equation based on an infiltration equation proposed by Swartzendruber. Comparisons made with a differentiated form of an infiltration equation by Swartzendruber and Youngs (similar to the form of Philip's) or Swartzendruber's proposed infiltration equation were not, generally, greatly different. Additions of random errors in the data through computer simulation also did not change the resultant hydraulic conductivity values in the cumulative runoff method very much from the original data's determined hydraulic conductivity values. Thus using cumulative runoff versus time to determine hydraulic conductivity has shown to be reliable.
