Model Study of Hopper Dredge Dragheads. Hydraulic Model Investigation.

Abstract

The investigation was conducted to determine the factors affecting the performance of dragheads and to develop parameters for use in the design and operation of dragheads when dredging in sand. The study was conducted in a 60- by 10-ft flume with a 1:6-scale model of the draghead and suction line. The suction line was attached to a centrifugal pump mounted on a carriage which could be made to travel the length of the flume on rails set on top of the flume walls. The scope of the investigation was not sufficiently broad to permit the development of all of the relations affecting the performance of the various types of dragheads but did provide sufficient information to permit the development of indications having practical applications in the design and operation of dragheads for hopper dredges.
