Abstract:

The effects of canal transients on scheduling water delivery to an irrigated area are described using a linearized form of flow equation obtained from a zero-inertia momentum equation and the continuity equation. Results show that neglecting transients can result in supplying less than the required or contracted amounts of water. A methodology by which lag times can be anticipated and the controls operated to minimize losses in delivery systems is given.
