Abstract
A system and method for calibrating an irrigation system to account for variations in flow rates caused by field elevation changes, pipe friction losses, water emitter nozzle wear, pressure-regulator inaccuracies, and other factors. A calibration map is created to account for the flow rate variations and then consulted to control operation of the irrigation system.
