FLOW AND BED DEFORMATION IN AN OPEN CHANNEL WITH A PERMEABLE RUBBLE MOUND GROYNE

Abstract

In this study, a numerical analysis and a laboratory experiment were carried out in respect to an open channel flow field with a movable bed in which a permeable groyne was installed. By comparing the agreement between the analysis and the experiment, the influence of the permeable groin to the open channel flow and movable bed erosion were discussed. The numerical method was expected to provide knowledge to the design of river structure such as permeable rubble mound groyne.
