Interpretive Summary: Water is becoming a scarce resource, and agricultural water users are under pressure to use water more judiciously. For many large irrigation projects, the physical infrastructure that delivers water to users influences their ability to manage the water supplied to them. Most large water delivery systems convey and distribute water with canals rather rthan pipelines. For large-scale systems, canals are an order of magnitude less expensive than pipelines. Infrastructure improvements (e.g., conversion to pressurized pipelines) are typically very expensive relative to changes in operations. Operations can be improved by providing canal operators with better tools for determining control actions. This book chapter discusses various options for the design of hydraulic structures for irrigation canals. The options are discussed in terms of how they influence operation of the system and the performance of water delivery to users. This information should be useful to design engineers, irrigation districts (particularly those in Mexico and Spanish-speaking countries), Mexico's National Water Commission, and the World Bank.

Technical Abstract: The success of irrigated agriculture in arid areas is strongly influenced by the dependability and the reliability of the water supply and the ability of the water delivery system to distribute it appropriately. The purpose of this chapter is to present concepts for design of open channels and associated control structures as influenced by the properties of open channel water flow and the needs of water delivery. It covers basic hydraulics of canals and structures, control structure design and remote and automatic controls.
