Abstract:

Increased rates of landsliding and coastal recession ensue on the downdrift coastwhen a formerly ample supply of beach material is impeded by a barrier such as a groyne field, strongpoint or jetty. While the phenomenon is well known as the terminal groyne effect, the actual mechanisms associated with this can be complexwhere there is a long history of piecemeal coastal protection and the original littoral drift supplywas variable. Rising sea levels will force selective protection for vital infrastructures with retreat allowed elsewhere, thus downdrift erosion will become of increasing concern. Research studies examining the forms and rates in which it occurs are being undertaken at Southampton University as a timely contribution for future coastal zone planning. © 2007 Taylor & Francis Group.
