One of these causes is sand mining on beaches and dunes. Regulations exist but implementation of the legislation is made difficult due to the huge demand of sand and gravel to feed ambitious programme of housing and industrial development. This paper describes the approach and methodology foreseen to exploit off shore sediment mining as an alternative to respond to this need. A case study on Tipasa site is included. First results related to survey, samples sediment and 2 D model tests are given.<P>
