Biography

 Dr. Tom Ravens is a Professor in the Civil Engineering Department at UAA.  His research is focused in two principal areas: coastal processes and renewable energy (specifically hydrokinetic energy).  His research includes field, laboratory, and modeling work.  His coastal processes research includes studies of hydrodynamics (waves and currents), sediment transport, flooding, water quality, coastal erosion and geomorphic change.  In the area of renewable hydrokinetic energy, Tom is leading projects that assess the in-stream hydrokinetic potential for the state of Alaska and for the Contiguous U.S.  In addition, he and graduate students are examining the hydraulic and sediment transport impacts of hydrokinetic energy generation.  Finally, Tom and colleagues have designed and built a flume to test the abrasion resistance of critical hydrokinetic device components in sedimented waters.

Tom's research has involved numerous graduate and undergraduate research assistants.  He is currently supporting four full-time graduate research assistants.
