Soil infiltration rates are generally reduced by the intermittent application of water
during surge irrigation such that this technique can be used to increase the wetting front advance
compared to continuous flow and to control runoff. Surge flow principles related to water advance
and infiltration in furrows are summarized. Computer models to simulate surge flow irrigation are
noted, particularly the kinematic wave model which has become the standard for surge irrigation.
Commercial valves and controllers are available for automating surge irrigation systems. Field
test results with different soil and field conditions at a number of locations are discussed. Results
have varied but show that the greatest effect on infiltration rates occurs during the advance phase
on light-textured soils and during the first irrigation of the season or following tillage.
