CURRENT S&T / RESEARCH - Contributing to Environment Canada’s mandate to ensure water is conserved and protected

  • Modelling and measurement of cohesive sediment transport processes in aquatic ecosystems
  • Stability of contaminated sediment deposits in areas of concern
  • Source tracking of sediment using radionuclides as tracers
  • Sediment transport modelling in St. Clair River in support of IJC's Upper Great Lakes Study
  • Entrapment of fine sediment in coarse sediment substrate
