SCOUR AROUND STRUCTURES

Eco E. Bijker

Abstract


The physics of scour around structures and especially underneath pipelines is discussed. It is demonstrated that a combination of current and waves with an equal bottom shear stress as a uniform current gives lower scour rates than a single current with the same bottom shear stress. The principle of the performance of scale series is discussed and it is shown that this method has still some weak points.
