Agronomy, Madison, WI. 181-194 Interpretive Summary: Interpretive summary: Features, evaluation criteria, and levels of implementation for automated irrigation systems are described but specific criteria and methods for actual design are not included. A brief history of research and implementation of systems for automated canal deliveries and surface irrigation, illustrates the difficulties in improving water application efficiencies when the infiltration rate is greatly affected by individual soil and slope conditions. Current automation practices use sprinkler or drip systems to achieve significant water and labor savings.
Technical Abstract: Technical abstract: Research and implementation of automated surface irrigation and canal delivery systems are described briefly. Although surge irrigation and cablegation demonstrated significant water and labor savings, significant adoption has not occurred because the irrigation industry does not have reasonably priced product that integrates the particular soil, slope, and water flow conditions to achieve improved system performance. Adoption of automated sprinkler and drip systems is occurring because the uniformity and efficiency of irrigations are not affected by the natural variations in soil and slope. Specialized application systems which moderate the aerial environment surrounding high value crops, reduce production losses due to frost damage and heat stress.
