R. Blair Hanna
Project Engineer
Dr. Hanna has more than 15 years' experience in hydrologic and water quality modeling, groundwater modeling and water resources engineering. His considerable skills augment the high level of water quality modeling expertise at Hydrosphere and add depth to our existing groundwater modeling and water resources engineering practices.
Dr. Hanna's accomplishments include a number of integrated modeling projects. For the USDA, he developed a hydrologic and water quality model to investigate agricultural hydrology and to assess the impacts of best management practices on water quality in the Uncompahgre and Gunnison Rivers in western Colorado. For the USGS, he developed river basin and reservoir water quality model applications for hydrologic and biologic research, including 1) a model simulating the effects of temperature control device operations on in-reservoir water quality and downstream thermal conditions at Shasta Lake, California; and 2) a decision support system for investigating basin management impacts on water quality throughout the Klamath River basin in Oregon/California.
His research has also included geochemical groundwater modeling: at the University of Colorado, he developed a two-dimensional model describing dissolution and growth of hydraulic conduits in karst aquifers.
His research has been published in numerous conference proceedings, USGS Open File Reports, and in the refereed journals: Journal of the Water Resources Planning and Management Division (ASCE), Ecosystems, Environmental Management, Journal of Lake and Reservoir Management, and Water Resources Research.
Dr. Hanna holds a PhD in Civil Engineering from Colorado State University, an MS in Civil Engineering from the University of Colorado and a BS in Computer Science from Syracuse University.
