Timothy K. Gates is a water resources systems engineer and a Professor of Civil Engineering at Colorado State University. He received a B.A. in 1978 from Louisiana Tech University and an M.S. in 1980 from Colorado State University, both in Agricultural Engineering, and a Ph.D. in 1988 from University of California, Davis in Civil Engineering. Prof. Gates has served on the faculty at CSU for twenty years where he has taught academic courses in open channel flow, fluid mechanics, hydraulic engineering, hydraulic structures/systems, hydrology, groundwater engineering, and solid dynamics. Prof. Gates has directed or co-directed research and training projects with total funding of about $5.6 million over the last 19 years. In addition, he has served as an independent consulting engineer with the United States Agency for International Development; the United Nations Development Program; Camp, Dresser & McKee, Inc.; Keller-Bliesner Engineering; D'Appolonia Environmental Services; the Denver Water Dept., the Governance Committee of the Platte River Cooperative Agreement, Devon Energy, Pennaco, ARCADIS & GM, the Riverside Ditch Company, Greg Lewicki and Associates, Pueblo Wastewater, Boxelder Sanitation District, and Central Mutual Insurance Co. on projects related to irrigation-and-drainage hydraulics, salinization of irrigated agricultural regions, water quality for irrigated agriculture, irrigation-induced pollutant loading to rivers, and river-basin modeling. He has designed and conducted numerous short courses and special training programs in open channel flow, irrigation and drainage engineering, and groundwater. Prof. Gates spent a total of about four years in Egypt working on various irrigation projects. He also has consulted in India, Sri Lanka, and Australia on irrigation projects.
