Learning Outcomes:
Students will be able to:
•         understand the pros and cons of different types of high efficiency irrigation systems.
•         acquire a comprehensive understanding of the design of HEIS.
•         demonstrate ability to design and evaluate HEIS
•         integrate HEIS designs into the operational requirements of irrigation projects
