“…The accuracy of these hydrodynamic simulations is affected by the wind drag formula and corresponding wind drag coefficients specified in the model. Drifting buoys were deployed and ADCP measurements of velocity were obtained in Lake St. Clair (Holtschlag, Syed, and Kennedy, 2002) to help confirm the adequacy of the original wind formula used in RMA2 (Donnell and others, 2003). Specifically, buoy deployment data were compared with the movement of hypothetical drogues.…”

Source areas to public water intakes on the St. Clair-Detroit River Waterway were identified by use of hydrodynamic simulation and particle-tracking analyses to help protect public supplies from contaminant spills and discharges. This report describes techniques used to identify these areas and illustrates typical results using selected points on St. Clair River and Lake St. Clair. Parameterization of an existing two-dimensional hydrodynamic model (RMA2) of the St. Clair-Detroit River Waterway was enhanced to improve estimation of local flow velocities. Improvements in simulation accuracy were achieved by computing channel roughness coefficients as a function of flow depth, and determining eddy viscosity coefficients on the basis of velocity data. The enhanced parameterization was combined with refinements in the model mesh near 13 public water intakes on the St. Clair-Detroit River Waterway to improve the resolution of flow velocities while maintaining consistency with flow and water-level data. Scenarios representing a range of likely flow and wind conditions were developed for hydrodynamic simulation. Particle-tracking analyses combined advective movements described by hydrodynamic scenarios with random components associated with sub-grid-scale movement and turbulent mixing to identify source areas to public water intakes.

Source areas to public water intakes on the St. Clair-Detroit River Waterway were identified by use of hydrodynamic simulation and particle-tracking analyses to help protect public supplies from contaminant spills and discharges. This paper describes techniques used to identify these areas and illustrates typical results using selected points on St. Clair River and Lake St. Clair. An existing two-dimensional hydrodynamic model of the St. Clair-Detroit River Waterway was reparameterized to improve estimation of local flow velocities. Improvements in simulation accuracy were achieved by computing channel roughness coefficients as a function of flow depth, and by determining eddy viscosity coefficients based on velocity data. The reparameterization was combined with refinements in the mesh geometry near 13 public water intakes on the St. Clair-Detroit River Waterway to improve the resolution of flow velocities while maintaining consistency with flow and water-level data. Scenarios representing a range of likely flow and wind conditions were developed for hydrodynamic simulation. Particle-tracking analyses were used to combine advective movements described by hydrodynamic scenarios with random components associated with sub-grid-scale movement and turbulent mixing to identify source areas to public water intakes.
