  • Biography

    Dr. Benjankar joined Center for Ecohydraulics research, University of Idaho, Boise, ID as a Postdoctoral Researcher in August 2009. His experience spans several focus areas within water resources engineering, with particular emphasis on floodplain physical processes, riparian vegetation, aquatic habitat and river restoration. His primary study area has been the Kootenai River in North Idaho and South Fork Boise River located in the Central Idaho, where he has constructed several one- and two-dimensional hydrodynamic and ecological models to represent the prevailing physical processes (e.g., flow depth, velocity, shear stress, flood duration, and stream temperature) over a large floodplain and river channel, to evaluate how altered processes influence habitat (riparian and aquatic) conditions. Development of a riparian vegetation succession model as part of his dissertation to aid in analysis of ecological impact of hydrological alteration and in planning of future restoration actions was another focus of his effort.
