  <dc:description xmlns:dc="http://purl.org/dc/elements/1.1/">Beach re-building - also known as beach nourishment, is the process of adding sediment to a beach to make it higher and wider. In an era of sea level rise, beaches are under serious threat - many are already adversely affected by manmade defences that have reduced the natural sediment supply. Beaches are a key natural, social and economic resource for Wales - they play a vital role in sustaining coastal tourism and underpin important nature conservation and landscape sites and acts as 'natural' coastal defences, dissipating wave energy, helping to protect both natural and manmade structures. During 2009/2010 a Steering Group comprising The Countryside Council for Wales (CCW), The Crown Estate, British Marine Aggregates Producers Association (BMAPA), Welsh Government, and the Environment Agency Wales (EAW) commissioned a Pilot Study to begin investigating the issues relating to the use of aggregates (sand, shingle, gravel, etc.) for beach nourishment in Wales, specifically in relation to the potential requirements for the quantity of material that may be needed to maintain Welsh beaches at current and future risk. The study is, in essence, a short data and literature review to establish the current level of knowledge regarding the ecological impacts (both positive and negative) of beach nourishment on the intertidal ecology of Welsh beaches. The potential impacts of more 'traditional' hard engineering and the use beach control structures are relatively well understood by coastal engineers, while the potential impacts of beach nourishment are less well known by those responsible for all aspects of beach management. The aim of the study is to look at the ecological effects (including potential benefits or adverse effects) of re-building beaches. This considers the most appropriate places for beach re-building, the methods used (including timing of works) and the suitability of different types of material.</dc:description>
