Abstract | ||||
Undistorted fixed bed physical model was used to examine a new groins alignment, which is not connected to the shoreline, in order to reduce the downdrift erosion and to minimize the trapped sediment at the updrift.. .The model was constructed in the wave basin of the Hydraulics ~esearch Institute (Em), Delta Barrage, where both wave height and current velocity, in two directi&, beforeand after the groins' construction were measured. The physical model succeeded in simulating the coastal groins and relating phenomena which helped to understand the complex interaction between waves, current, sediment, and groins. It was concluded that the proposed alignment is successllly reduced the erosion in the downdrift and allowed movement of longshore sediment transport and protects the located irea between the groins. | ||||
