Abstract

SURGE irrigation, the intermittent supply of water to
furrows or borders, generally reduces infiltration
rates. However, the degree of infiltration reduction is
variable and difficult to predict. Mechanisms by which
surge irrigation reduces infiltration rates include (a)
consolidation of the furrow perimeter due to increased
soil water tension during flow interruptions, (b) filling of
cracks which develop during flow interruptions with bed
load during the following surge, (c) forced settlement of
suspended sediment on the furrow perimeter when the
water supply is interrupted, and (d) greater sediment
detachment and movement caused by more rapid
advance of the surged stream front.
