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.

“…A Peclet number of 21.9 was estimated for the hydrodynamic model representing the St. Clair-Detroit River Waterway (Holtschlag and Koschik, 2004) based on 2002 ADCP surveys of St. Clair River (Holtschlag and Koschik, 2003a) and Detroit River (Holtschlag and Koschik, 2003b). This value was determined on the basis of parameter estimation techniques and fell within the range of 15 to 40 commonly used for Peclet numbers (Donnell and others, 2003).…”
