A ponding monitoring and detection system monitors, detects, and predicts ponding in an irrigated field in essentially real-time. The ponding monitoring and detection system also monitors and records locations of detected and predicted ponding.

System and method for detecting ponding in irrigated fields

A system and method for calibrating an irrigation system to account for variations in flow rates, motor operating parameters, and other parameters 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 or other parameters and then consulted to control operation of the irrigation system.

An irrigation system includes a control arrangement which receives field information relating to an area to be irrigated and source information relating to one or more water sources which supply water to the irrigation system. The control arrangement optimizes an irrigation plan based on the field information and source information and then controls one or more irrigators in accordance with the plan. The control arrangement may pulse valves positioned on the irrigator on and off in order to control the amount of water applied to the land by individual outlets on the irrigator. Latching valves may be used.
