Rate of advance and infiltration field data were used to develop a characterization of infiltration under surge irrigation. The potential benefits of surge irrigation were quantified, discussed and related to the infiltration phenomenon. The surge infiltration function appeared to undergo a step reduction from the time dependent rate to the basic rate after one complete wetting and dewatering cycle. This infiltration rate reduction led to reduced amounts of time and water necessary to complete advance when surged applications were used instead of continuous applications. The surge infiltration phenomenon also caused a reduction in advance time differences between successive irrigations as well as between furrows with different degrees of compaction.
