Effects of a Proposed Bushy Park Entrance Canal Relocation Cooper River, South Carolina

The effect of a proposed entrance canal on tidal flushing of Bushy Park Reservoir, 27 km north of Charleston, SC, was tested using a numerical model, and a canal cross section that would maintain present flushing was developed by trial. A previously developed two-dimensional model computed dynamic f...

Description
Summary:The effect of a proposed entrance canal on tidal flushing of Bushy Park Reservoir, 27 km north of Charleston, SC, was tested using a numerical model, and a canal cross section that would maintain present flushing was developed by trial. A previously developed two-dimensional model computed dynamic flow velocities, vertical velocities, and water-surface elevations for two verification periods, and for various entrance canal cross sections. The model was verified to tidal volume exchanges and water levels measured in the field. No data were available to verify vertical velocities. The model was then used to test a number of entrance canal geometries (width and depth) for the proposed relocation, and the reservoir tidal volume exchanges and flushing were compared to existing conditions. Existing tidal flushing can be maintained in Bushy Park Reservoir by constructing an upstream entrance canal of sufficient size. Recent ocean chloride intrusion data were used to confirm that the proposed site for the Bushy Park entrance canal would effectively reduce chloride intrusions. Analysis of previous intrusion events indicated that relation of the Bushy Park entrance canal to the proposed site near Mempkin will eliminate the salinity intrusion events if other conditions (weekly inflow schedules for instance) remain the same.
