Abstract: The study of turbidity generation indicates that, in general, turbidity increases with an increase in the cutter speed and an increase in the cutter swing velocity. A silt curtain deployed in front of the cutter was found to be very effective in reducing turbidity. Since the turbidity cloud is trapped by the curtain and reflected towards the cutterhead, an increase in pumping efficiency can also be expected.
