The objective of this study was to determine if small vessels, operating in shallow waters, have any measurable effects in producing increased turbidities by the resuspension of fine sediments which may affect submerged aquatic vegetation (SAV). A two-phase approach was used, consisting of field tests in a suitable sub-estuary of the Chesapeake Bay, and laboratory measurements of propeller effects. During field trials, two different vessel types were used to make passes at set speeds over known water depths. Before and after measurements of light extinction, transmission, and gravimetric suspended sediment determinations were used to identify effects. Laboratory experiments were conducted to delineate propeller contribution to possible resuspension; this was done using laser-doppler anemometry to map the turbulence field produced by propeller action.
