Design of a Reef for Coastal Protection
The beach at Pudussery has been badly eroded. The rock armour placed there to stop the erosion marred the beauty of the beach. An agency was commissioned to go into the matter and suggest remedies. The scheme suggested by them included a reef on the northern side. The three components of this scheme were a raised work area, a rubble bed for a wedge to be installed and a triangular-shaped wedge. The bed is submerged and was designed based on the formulations of Van der Meer. Engineering design of the components had to be carried out before execution. It was decided to use steel for fabrication of the wedge for easiness of construction. The paper deals with the engineering design of the components.
