Contents Notes
"Field evaluations of furrow irrigation practices at three Colorado locations were conducted during the 1979 irrigation season. The data were utilized to assess four alternative field evaluation procedures and develop cost effectiveness relationships for each method. A simulation formulated from volume balance concepts was also developed and calibrated using the field data. The model was used to evaluate the relationships among furrow hydraulic and performance parameters so that proper alternatives for improving irrigation efficiency could be determined. Analysis of spatial and temporal variabilities in the field indicates that large errors are likely in field assessments unless the study is comprehensive. Testing should include the first seasonal irrigation and at least three later irrigation events. At least six individual furrows should be studied on each field. Relationships among soil properties, furrow hydraulics, and irrigation efficiency were not predictable unless specific intake (infiltration) relations were utilized as input data. However, with this information it was possible to identify the effects of changing various irrigation practices upon irrigation efficiencies."
