Equivalent Kostiakov parameters for SCS infiltration families

The US Soil Conservation Service (SCS) formula for infiltration families, which are defined as water intake rates of soil in inches per hour at terminal time, is widely used in irrigation research. An alternative formula is the two-parameter Kostiakov equation whose simplicity makes it popular among modelers. Equivalent Kostiakov equation parameters are established for the different SCS infiltration families by minimizing the deviations between the representation k and (alpha) in the Kostiakov formula F = kt(raised to the power alpha). F represents the cumulative infiltration amount in inches or centimeters and t represents time in minutes.
