4. Strategic approach to dune management

Managing marine erosion of dunes requires an understanding of the physical and ecological processes active both at the site and in the wider coastal environment, an understanding of the risks to the human and natural environment, an understanding of the effectiveness and consequences of the possible management decisions and a clear understanding of the short and longer term management objectives for the site. All shoreline sites are part of larger coastal systems. Waves and currents active on a section of beach are often generated by forces that are remote from the site. The sediment that makes up the beach is often derived from a source that is both temporally and physically distant. As a result, management operations can have unforeseen impacts locally or even on sites many miles away, either immediately or, potentially, years later.
