Jason Rutyna, PE, is an environmental engineer with LimnoTech. Jason has a master’s degree in Civil and Environmental Engineering from Wayne State University with a focus on water resources and environmental engineering. Jason has experience with providing clients with scientific and engineering analyses in a variety of projects that involve hydrodynamic/hydraulic models, hydraulic transient/pneumatic models, water quality models, TMDL modeling and analysis, mixing zone modeling, water quality data analysis, and three-dimensional geostatistical interpolations. Jason has been involved with numerous CSO tunnel projects, and has applied LimnoTech’s SHAFT model to evaluate surges, transients, and pneumatic effects in these systems. Jason has also applied the open source computational fluid dynamic (CFD) software program OpenFOAM to evaluate street flooding issues related to a CSO tunnel.
