Abstract: The Tylers Beach, Virginia, Dredged Material Plume Monitoring Project (TBMP) was conducted during the period 27 September to 4 October 1991. The project was conducted under the Dredging Research Program Technical Area 1, entitled "Analysis of Dredged Material Placed in Open Water," in support of the U.S. Army Engineer District, Norfolk. The objectives of the TBMP were to (A.) collect suspended material concentration data and current data to determine the potential for dredged material issuing from a pipeline discharge to reach environmentally sensitive areas adjacent to the placement site, and (B.) continue development of PLUmes MEasurement System (PLUMES) for monitoring dredged material plumes. This report provides an overview of the equipment and procedures used during the TBMP, together with a presentation of the TBMP data and analysis results. The TBMP produced an extensive, high-quality data set from 12 acoustic surveys and numerous suspended material and bottom grab samples. Components of the TBMP include acoustic backscatter measurements from an Acoustic Doppler Current Profiler; water current measurements from two systems; in situ water sampling; monitoring of ambient conditions; and accurate ship positioning. Under calm weather conditions such as those encountered during the project, the discharge of dredged material at the placement site did not cause an increase in the naturally occurring concentration of suspended material on an oyster seeding ground called Point of Shoals.
