Abstract

A method and apparatus for dredging in flowing waters comprising a support member (3) carrying thrust means (13) so that the thrust means (13) is directed downwardly towards the area to be cleared, the support member (3) being mounted in the water so that in operation it presents a surface towards the flow of water which causes a resultant downward component of force to balance the upward component of force caused by the thrust means (13).
