ABSTRACT:
An apparatus for preventing intrusion of sediments into quiet water berthing areas which is particularly adapted for use in berthing areas of the type having spaced apart fixed structures extending downwardly to the floor of the water body and defining an opening to the berthing area of a size sufficient to permit the ingress and egress of transiting vessels. The apparatus includes a spar curtain barrier made up of a plurality of flexible sections each of which comprises a ballasted spar buoy to which a length of flexible curtain fabric is attached. The sections are secured together to form an integrated structure adapted, in its closed position, to extend between the spaced apart fixed structures defining the berthing area. The spar curtain depends downwardly to a level proximate the floor of the berthing area and can be opened by a single workman in a short period of time to permit the entry or exit of the transiting vessels. In its open position the curtain barrier is neatly and compactly stacked, in an accordion-like fashion, against one of the fixed side structures of the berthing area.
