Tim Ward

Professor Ward has expertise in the broad area of surface water hydrology with specific activities in modeling of hydrologic and hydraulic systems, field experimentation, erosion and sediment transport studies, water quality, and watershed management.  He has conducted work in most of the western United States and the countries of England, Germany, Brazil, Honduras, Kazakhstan, and India.  Dr. Ward has been principal investigator or co-principal investigator on over 50 funded research projects and has conducted or participated in over 35 consulting jobs.  He has authored or co-authored over 200 papers, reports and presentations.  For twelve years, he was co-principal investigator on an interdisciplinary team at New Mexico State University that modeled the hydrology, water quality, hydraulics, fish habitat, and recreational economics for all the river basins in New Mexico.  Dr. Ward and his colleagues were co recipients of the 1990 American Water Resources Association Boggess Award for the best paper in the Water Resources Bulletin titled "Development of an Interdisciplinary Planning Model for Water and Fishery Management."  Dr. Ward received the 2013 Arid Lands Hydraulic Engineering Award from ASCE/EWRI in recognition of his noteworthy contributions to the advancement of hydraulic engineering in arid and semi-arid climates.
