Abstract

The harbour breakwaters at Durban in conjunction with the dredging of the harbour entrance cut off the sediment supply to the important bathing beaches of the city, necessitating a beach restoration scheme. This paper reviews this scheme. Before 1977, the measures to restore the beaches included an underwater mound, beachfill and rock groynes. After 1977 and following a previous review, it was recommended not to complete the mound, to place initial beachfill, regularly nourish the beaches and to build low-level groynes. Implementation started with a sand pumping scheme and 600 000 m3 of beachfill followed by the building of three multi-functional pier/groynes. Monitoring of the beach restoration scheme enabled valuable experience to be gained on aspects such as the loss rate of sand from the beaches, beach profile and scour levels alongside the pier/groynes and on the determination of a potential erosion line and building control zone. This paper concludes with some important lessons learned from the scheme.
