ABSTRACT:
A turbidity control system for dredging operations wherein turbidity adjacent the dredge head is controlled by one or more operating characteristics of the dredging operation. The dredge head includes water jets for agitating, slurrying, loosening the material being removed and directing the material toward the dredge head and control apparatus regulating the water flow into the dredge head, the direction of the jets, the rate of water removal from the head, and the rate of dredge head advancement is adjusted in accord with the turbidity to permit dredging operations within acceptable environmental limits. A turbidity sensor may be mounted adjacent the dredge head to sense the extent of turbidity existing, and the sensor may be used to automatically operate the control apparatus.
