Water-quality specialist Evans is CALS Biological and Agricultural Engineering Department head


Robert Evans

Dr. Robert Evans, a prominent water-quality expert based at N. C. State University, is the new head of the university's Department of Biological and Agricultural Engineering in the College of Agriculture and Life Sciences.

Evans, recently named a fellow of the American Society of Agricultural and Biological Engineers, has been a BAE Department professor since 2003 and its extension leader since 1997.

His 1991 doctorate, 1981 master's and 1976 undergraduate degrees in biological and agricultural engineering are from N.C. State's BAE Department.

Evans' previous BAE department posts include associate professor and department extension leader from 1998 to the present, assistant professor from 1992 to 1998 - he took on department extension leader's duties in 1997 - and North Carolina Cooperative Extension specialist from 1983 to 1992.

Evans is recognized nationally and internationally as a leader in water table management and drainage water quality. His applied research led to significant publications and extension education in several areas, including design and evaluation of drainage practices for manipulating shallow water tables, wetlands hydrologic evaluation using both field monitoring and simulation modeling techniques for delineation and restoration purposes, stormwater water quality analysis emphasizing practices to reduce nutrients and sediment transport to sensitive surface waters, and riparian and in-stream constructed wetlands' design and management. He has mentored more than 35 graduate students and chaired 14 graduate advisory committees.

A licensed professional engineer registered in North Carolina, Evans is a leading authority on the use of DRAINMOD. This simulation model is used to evaluate high water table soils' hydrology and to measure on-site soil and site hydraulic properties critical to hydrologic evaluation. He initiated the Extension Water Table Management Program, which led to the adoption of controlled drainage as a best management practice for North Carolina and its implementation across more than 600,000 acres. His water-quality research and Extension initiatives increased state net farm income by $8 million annually and reduced unwanted agricultural nitrogen in streams by three million pounds.

Author or co-author of more than 180 research, Extension or technology transfer publications, he has received awards and honors from many professional groups, including the N.C. Irrigation Society, for which he has been a technical advisor since 1993. He has received the North Carolina Soil and Water Conservation Society's Professional Achievement in Water Quality award and USDA superior service and group excellence awards.
