Flow Interruption Effects on Intake Rate and Rill Erosion in Two Soils

Abstract: Efficiency of surface irrigation is often low because of poor infiltration uniformity, resulting from relatively long periods of infiltration at the upstream end and short periods of infiltration at the downstream end of the field. Surge irrigation, the intermittent supply of water to furrows, generally reduces soil intake rate (IR) and improves moisture uniformity over the entire field. However, IR reduction varies from one irrigation scheme to another, depends on soil and water properties, and is difficult t… Show more

“…The infiltration depth of water into the soil was less for SI than CI by 135 to 390%, and was consistent with previous studies (Goldhamer et al 1987;Evans et al 1987;El-Dine and Hosny 2000;Kanber et al 2001;Sirjacobs et al 2001). However, Amali et al (1997) reported similar infiltration depths under SI and CI, and Kanber et al (2001) found that infiltration depth under SI decreased dramatically when the inflow rate was lowered and the cycle ratio decreased.…”

“…The mechanism responsible for the surge effect is that reduced infiltration rates in the wetted portion of the field allows faster advance of subsequent irrigation streams towards the end of the field (Walker and Skogerboe 1987). Possible causes of this intake rate reduction are: water redistribution in the soil, consolidation of soil, surface seal formation, crack filling, greater sediment detachment and movement, forced deposition and consolidation of suspended sediment on furrow perimeter when water supply is interrupted, and air entrapment (Kemper et al 1988;Walker and Skogerboe 1987;Sirjacobs et al 2001).…”

“…Consistent impacts to bulk density are not apparent among sites in samples collected in 2004 (Table 4). Sites receiving CBNG irrigation water for 4 yr (Site 1) may be at risk of increased bulk density from swelling of clay (especially smectites) on wetting (Sirjacobs et al, 2001) and from potential clay particle dispersion in surface soil layers with subsequent leaching of these particles that accumulate in subsurface pores. Except for irrigated Site 3 (0-5 and 5-15 cm), irrigated Site 4 (90-120 cm), non-irrigated Site 6 (0-5 cm), and non-irrigated Site 7 (0-5 cm), most sample depths at all sites had >25% clay, indicating increased likelihood of restricted water permeability and reduced leaching potential of Na + rich CBNG waters (Ben-Hur et al, 1985;Levy et al, 1998).…”

“…Shainberg et al (1996) carried out a laboratory investigation into the interactive effects of flow characteristics and soil properties on rill erosion. Sirjacobs et al (2001) studied the effect of flow interruption on rill erosion for different soils. They found that interruption flow obviously reduced rill erosion and the reduced effect depended on soil properties and rill flow rate.…”
