Interpretive Summary: Accurate measurement of irrigation water is essential for managing the combination of natural resources and conservation techniques involved in improving farm production in both the United States and Mexico. This chapter extends technology transfer of successful flow measuring devices and methodology to our southern neighbor in cooperative efforts to improve irrigation water use in the Western Hemisphere. The information presented is of interest to canal operators, researchers, and farm irrigators dealing in water management and water measurement in canal systems, both large and small.

Technical Abstract: Flow measurement technology for irrigation canals is presented in this cooperative effort with a water agency that is part of the government of Mexico. This chapter consists of tables and design information for a number of commonly used weirs and flumes that are particulary suited for use in canals ranging from farm sizes to distribution system sizes. These include the older Parshall flumes, the H-flumes, and the long-throated flumes. The latter are especially featured and were developed by the Agricultural Research Service in recent years. Both hydraulic design and construction advice are offered. Also featured are the hydraulic characteristics and design information for selecting and installing certain discharge control devices, such as the Neyrpic modules, that are commercially available. While this control and measurement information is available in the English language, it has not been generally available in Spanish language format.
