A Design Procedure for a Scour Jet Array.

Abstract

A scour jet array consists of a number of submerged horizontal water jets that are uniformly distributed along the base of a pier of quay wall within a harbor. The purpose of the array is to prevent the deposition of cohesive sediment within its immediate area by scouring the bottom with its jets. Laboratory measurements have shown that the shear stress distribution of a submerged wall jet is a function of the jet diameter and its discharge velocity. A design procedure is developed in which an optimum system may be selected from all candidate systems. The parameter of optimization is the minimum annual cost. The design procedure requires using either a computer program or a number of graphs.
