GEORGE H. HARGREAVES received bachelor's degrees in soils from the University of California, Berkeley and in Civil Engineering from the University of Wyoming. He has worked in soils, irrigated agriculture, or water resource development for various universities and governmental agencies. He retired in 1986 as Director of Research for the International Irrigation Center, Utah State University.

Professor Hargreaves has continued with consulting assignments, research, and preparation of professional papers.

In 1997 he received the Royce J. Tipton Award, the most prestigious award in irrigation given by the American Society of Civil Engineering (ASCE).

GARY P. MERKLEY is an Assistant Professor in the Biological and Irrigation Engineering Department at Utah State University. He grew up on a large irrigated farm in California and managed all irrigation activities before returning to complete his Ph.D. at USU. He has developed several software applications and simulation models for canal hydraulics and irrigation water management, and continues to develop new applications. Dr. Merkley has worked and lived overseas through-out much of his career at USU, and currently teaches graduate classes at USU, conducts research, and works on various domestic and international irrigation projects.
