Management of the water supply canals in a rotation irrigation system can affect the uniformity of water delivery to farms. Different management procedures are needed, depending on the water availability. Management during periods of water shortage is critical. Managing the flow of water in lateral canals is compared with the management of flow in the supply canal for conditions where there is a water shortage at different times during the irrigation season. Changing the ways irrigation flows are handled can significantly reduce management losses and improve equity of water delivery. A procedure for adjusting rotation intervals to improve water management is illustrated.
