Abstract

A kinematic wave mathematical model which simulates the hydraulics of continuous flow furrow irrigation was linked with a crop yield model and used in combination with an economic model to analyze the effects of inflow rate, water infiltration characteristics and furrow length on uniformity of infiltrated water, runoff, gross profits and optimal number of 12 hour irrigations for corn (Zea mays) assuming other management practices to be constant. Higher uniformity of infiltrated water but more runoff and, in some cases, more deep percolation resulted from increased flow rates. Increases in uniformity of infiltrated water leads to greater profits, which are however offset by the associated increases in runoff and deep percolation. The study shows economically optimal water management for furrow irrigation can be obtained with proper balance between changes in the input variables and runoff and to some extent deep percolation.
