Tammo Steenhuis is a Professor in the Department of Biological and Environmental Engineering. He is also one of the faculty members leading the dynamic and innovative Soil and Water Group. S&W’s broad mission relates to the management of soil and water resources and tries to improve the understanding of physical, chemical, and biological processes related to water flow. The ultimate goal is to improve and protect water resources and ecological systems throughout the world in socially conscious ways.
Professor Steenhuis’ research is carried out over a trillion-fold scale range, from transport of micro particles in soil pores to the effect of human interventions in the landscape on transport of water and sediment in large river basins. His research requires an understanding of how the landscape and people affect the water, sediment, nutrient, and other chemical flows in the landscape. His research program currently emphasizes the fate of agricultural nutrients and sediment transport in areas like in Black Creek in upstate New York and in cooperation with the School of Civil and Water Resources housed at Bahir Dar University in the Blue Nile Basin of Ethiopia.
Outreach and Extension Focus
The S&W Group looks at pesticides contamination of upstate New York aquifers and lakes in a project sponsored by the NYDEC. In addition, with funding of HED and USDA, it is improving the safety of drinking water supplies in the Ethiopian highlands. Additionally, it also works with the NYCDEP to assure the best quality water in the Catskills source watershed. Finally, in cooperation with the East African office of IWMI, it studies better ways to make use of available rain water, most of which presently runs out of the country.
Professor Steenhuis is teaching watershed management and research methods in Ethiopia. At Cornell, he teaches BEE 7540 Water Management in an Era of Growing Water Scarcity and BEE 4270 Water Measurement and Analysis Methods.
