Abstract:

Massive mining of dune sand on the north coast of Puerto Rico has impaired the natural ability of the dunes to protect the coast from high waves and long-term erosion. This paper presents a scientific basis for a dune management strategy that provides a degree of protection yet allows a supply of sand for mining. It presents a case history of large scale dune destruction caused by commercial mining, frontal erosion and breaching. It aims to demonstrate an approach for maintaining dunes in their best achievable condition through natural restoration and management which allows a degree of protection from storm waves and a source of sand for mining.
