A method of dredging comprising: suspending dredging apparatus from a vehicle, the dredging apparatus comprising: a chassis ; sediment agitating apparatus for disposal above a sediment layer on a waterbed, the sediment agitating apparatus comprising a fluid injector and an injector pump arranged to inject fluid through the fluid injector , the sediment agitating apparatus being mounted directly on the chassis ; separately an extractor, the extractor being arranged to move agitated sediment away from the waterbed, the extractor comprising an extractor conduit and an extractor pump arranged to pump agitated sediment through the extractor conduit, the extractor being mounted directly on the chassis ; and a connector for connecting the sediment dredging apparatus to the vehicle; disposing the dredging apparatus above, but not in contact with a waterbed to be dredged of sediment ; agitating the sediment with the sediment agitating apparatus ; extracting the sediment with the extractor; and moving the dredging apparatus around the water; wherein the sediment is transported and deposited away from an area being dredged by the natural movement of the water; characterised in that the fluid injector comprises one or more injector conduit , the injector conduit bearing a plurality of nozzles and wherein the extracted sediment is suspended underwater and into a higher water column above the sediment agitating apparatus. suspending dredging apparatus from a vehicle, the dredging apparatus comprising: a chassis ; sediment agitating apparatus for disposal above a sediment layer on a waterbed, the sediment agitating apparatus comprising a fluid injector and an injector pump arranged to inject fluid through the fluid injector , the sediment agitating apparatus being mounted directly on the chassis ; separately an extractor, the extractor being arranged to move agitated sediment away from the waterbed, the extractor comprising an extractor conduit and an extractor pump arranged to pump agitated sediment through the extractor conduit, the extractor being mounted directly on the chassis ; and a connector for connecting the sediment dredging apparatus to the vehicle; a chassis ; sediment agitating apparatus for disposal above a sediment layer on a waterbed, the sediment agitating apparatus comprising a fluid injector and an injector pump arranged to inject fluid through the fluid injector , the sediment agitating apparatus being mounted directly on the chassis ; separately an extractor, the extractor being arranged to move agitated sediment away from the waterbed, the extractor comprising an extractor conduit and an extractor pump arranged to pump agitated sediment through the extractor conduit, the extractor being mounted directly on the chassis ; and a connector for connecting the sediment dredging apparatus to the vehicle; disposing the dredging apparatus above, but not in contact with a waterbed to be dredged of sediment ; agitating the sediment with the sediment agitating apparatus ; extracting the sediment with the extractor; and moving the dredging apparatus around the water; wherein the sediment is transported and deposited away from an area being dredged by the natural movement of the water; characterised in that the fluid injector comprises one or more injector conduit , the injector conduit bearing a plurality of nozzles and wherein the extracted sediment is suspended underwater and into a higher water column above the sediment agitating apparatus. <EOS>
