Abstract
There are several different parameters that can be measured and used to describe the performance of water delivery service; flow rate, volume, duration, pressure, and frequency. The proper one(s) to consider depends on the project conditions and objectives. The overall performance of an irrigation water delivery system can be broken down into two components; the delivery schedule and operations. The performance of the delivery schedule can be evaluated by looking at the ratio of intended to required water (volume, rate, duration, etc.) and the performance of operations by the ratio of actual to intended water. The overall performance is expressed by the product of these two ratios; the actual divided by the required water. Statistical relations are provided to express equity, adequacy and reliability from measurement of these ratios.
