| 説明 | This is the RNLI slipway at Rye Harbour. The chap in the jeltex jacket is preparing his boat to carry out a riverbed survey of the lower reaches of the River Rother. Some areas require dredging more than others and it his job to specify which areas need dredging. The method used to dredge the river is called water injection dredging, a small jet is used to inject water under low pressure (to prevent the sediment from exploding into the surrounding waters) into the riverbed to bring the sediment in suspension, which then becomes a turbidity current, which flows away down slope and is carried away by natural currents, in this case the ebb tide. |
