Research Summary

I conduct research on transport and mixing processes in the natural aquatic environment to assess their impacts on water quality. My present research activities fall within two thematic areas:

Theme 1. Applied Research on Lake Hydrodynamics and Bio-Physical Coupling

• Field measurements are collected and computational lake modes are applied to investigate:
• The role of stratification in limiting vertical transport of plankton above mussel beds
• The impacts of physical processes and climate change on hypolimnetic oxygen depletion and harmful algae blooms
• The contaminant transport pathways surrounding drinking water intakes
• The internal wave dynamics in Great Lakes and Finger Lakes

Theme 2. Fundamental Research on Waves and Turbulence in Stratified Flows

• Laboratory and numerical techniques are applied to quantify the energy flux between the various internal wave groups in lakes, with an ultimate goal of understanding:
  • The energy transfer from the wind stress to the internal wave field
  • The nonlinear and nonhydrostatic energy fluxes through the internal wave spectrum
  • How internal wave energy is irreversibly lost to dissipation and mixing as internal waves shoal upon sloping topography
  • Sediment resuspension resulting from internal wave shoaling
  • Parameterization of these processes into field-scale computational lake models

Qualified students are being sought at the Masters, Doctoral and Post Doctoral levels for a number of funded research projects in the above areas. Prospective students are encouraged to contact Professor Boegman. Information on applying can be found here.
