An overflow system for a hopper dredger camprises an overflow tube; an inlet for taking in head water from the hopper; and a collector to collect the flow of head water entering the inlet and guide the flow to the overflow tube. The collector camprises a top portion to ensure substantially radial flow into the collector. At least one of the overflow tube and the inlet is adjustable for cantrolling flow into the overflow system. |
