Using a continuous-flow centrifuge, the suspended sediment concentrations in Narragansett Bay and Rhode Island Sound were measured. An average of 3.17 milligrams of sediment per liter was found in the Bay and 1.83 milligrams per liter in the Sound.

Most of the sediment entering the estuary from the tributaries was deposited near the head of the Bay, but a secondary depositional area was found near the center of the Bay in zones of weak and variable currents. The average rate of deposition for the entire bay during the fall months was 0.092 grams per square centimeter per year, and the net transport through the estuary was found to be 10 percent of the tributary sediment load, or 910 grams per second.
