CEE 555 Mixing in Environmental Flows


Physical processes involved in transport of pollutants by water; turbulent diffusion and longitudinal dispersion in rivers, pipes, lakes, and the ocean; diffusion in turbulent jets, buoyant jets, and plumes.

The course introduces the physical transport and chemical transformation processes that govern the fate and distribution of pollutants in the environment. It covers applications of fluid mechanics to problems of transport, mixing, and transformation in fluids. It introduces and analyzes the advective, diffusive, and dispersive processes occurring in the environment. The course also covers boundary interactions: air-water and sediment-water processes, an introduction to chemical and biochemical transformation processes, and applications to transport, mixing, and transformation in rivers, lakes, and coastal waters. The course includes hands-on laboratory sessions, as well as an on-campus field study on Boneyard Creek (depending on lab/equipment availability and weather).

Learning goals:

Upon completion of the course you will:

  • Identify the advective, diffusive and dispersive processes governing fate and transport of pollutants in the environment.
  • Develop the skills to represent transport and mixing processes analytically and using simple numerical models.
  • Develop analytical and experiential foundations to choose and utilize the proper numerical tools and instrumentation to study mixing and transport phenomena in the environment.
  • Assess potential effects of short- and long term changes in flow, obstructions and boundary conditions on the fate and transport of pollutants in the environment.
