Abstract

Cablegation is an automated furrow irrigation system in which the irrigation set moves at a slow, constant
rate across the field. This constant movement allows time and space to be interrelated, which simplifies collection of
furrow irrigation evaluation data. Specialized cablegation evaluation procedures are described and illustrated. Furrow
stream advance and recession times and tailwater runoff rates can be measured at any point in time. Thus, average
infiltrated depth and infiltration opportunity time can be easily determined. Water distribution uniformity can be
estimated from infiltration rate at the time recession begins and infiltration opportunity times. The infiltration function
can be estimated from average infiltrated depth and final infiltration rate
