Rollin H. Hotchkiss
Brigham Young University
Professor
Rollin H. Hotchkiss is a water resources engineering professor in the Civil and Construction Engineering Department at Brigham Young University. His research efforts to reduce fatalities at low-head dams are documented in several journal papers and conference proceedings. Current work on this topic aims to create user-friendly tools to determine the potential occurrence of submerged hydraulic jumps for any of the more than 13,000 low-head dams in a recently completed national inventory. Dr. Hotchkiss has authored more than 50 journal papers and more than 100 conference papers and was the 2017 ASCE Hydraulic Structures medal recipient. He teaches courses in fluid mechanics, 2D river modeling, hydraulic structures, and open-channel flow.
