College of Engineering
Postdoctoral Researcher

Campus Locations: Boise, Idaho

  • Research/Focus Areas
    • Use of hydrodynamic and ecological models to analyze ecological processes (riparian and aquatic habitat)
    • Interaction between hydrology and ecosystems
    • Channel and floodplain fluvial processes
    • Habitat and ecosystem (aquatic and riparian)restoration
    • Surface and sub-surface flow interaction (ground water and hyporheic flow) and its implications for ecological processes
    • Future impacts of climate variability on aquatic and riparian habitat
  • 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 river fluvial processes, interaction between hydrology and riparian and aquatic ecosystem including river restoration. His primary study areas have been located in Idaho, where he has developed several one- and two-dimensional hydrodynamic models to represent the prevailing physical processes (e.g., flow depth, velocity, shear stress, flood duration, and stream temperature) over a floodplain and river channel and coupled with ecological models 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 (http://www.casimir-software.de/ENG/veg_eng.html).
