Includes agrometeorology, crop water use, effective precipitation, comparison of methods, and accuracy of results using worldwide data. The soil water reservoir as a function of soils, layering, root growth, crop type, and management practices is examined. Covers methods of estimating reference crop evapotranspiration, irrigation efficiencies, effective and dependable rainfall, allowable deficits, and frequency of irrigation. Gradually varied flow computations are also introduced. Water Measurement Includes principles of water measurement and the selection, installation and use of weirs, flumes, and orifice devices.
Participants also carry out field evaluations of channel losses.
Scheduling fully and limited flexible systems. Scheduling with Limited Water Supplies Introduces the use of water production functions in estimating yields. Scheduling of supplemental irrigation during critical periods is examined. Training Farmers and Technicians in Water Management Includes development of training and extension materials and conducting training sessions for farmers and technicians on water management practices, including on-farm irrigation scheduling. Also, successes and failures of irrigation scheduling programs.
