Furrow irrigation is a complex phenomenon, mainly due to the medium upon which the water is transported, namely the soil. With surge irrigation, the phenomenon is further complicated by the multiple advances and the effect of alternate wetting and dewatering on the soil infiltration characteristics. Using one of the surge irrigation modeling techniques, the optimum management parameters for a particular furrow may be found if the conditions can be measured adequately. The objective of this study was to produce an evaluation procedure for surge irrigation that was accurate yet practical to use in the field. Using surge advance data recorded at 25m intervals along the furrow this study shows that the advance can be approximated from two time/distance and one distance point. Using this approximation results in an error of less than two percent for the application efficiency.
