Offered during the summer pre-session in even calendar years.
Description: A laboratory and field course which emphasizes irrigation water supply and distribution systems. Laboratory topics include performance of surface, sprinkler, and drip irrigation systems; pipeline hydraulics; flow in streams, canals, and irrigation pipelines; irrigation pumping systems; irrigation well hydraulics; and soil water properties. The field trip includes visits to irrigation water supply and hydroelectric power projects; water resources agencies; irrigation field research sites; and manufacturers and installers of agricultural irrigation systems.
Description: Theory and practice of on-farm irrigation management including: irrigation economics; soil-plant-water relations; evapotranspiration; remote sensing; irrigation scheduling; real-time operation and maintenance of irrigation systems; yield response functions and deficit irrigation; sensors and apps for irrigation; environmental impact of irrigation and drainage; impact of irrigation on consumptive use at the watershed scale; irrigation district operation and maintenance; and international irrigation development.
