Metadata: Ecological Effects of Re-Building Beaches in Wales
Abstract:
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.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Ten case study beaches were chosen to represent a range of issues around the coast of Wales and to include sandy beaches, sand and shingle beaches, high and low tourist areas and different flood and erosion risks. Using Phase 1 Intertidal maps provided by former Countryside Council for Wales (CCW) an area on each of the 10 study beaches was identified where beach nourishement might take place. The areas were reviewed by CCW experts and amendements made. Additional species and habitats that were considered important were also included in the data study. A literature study was carried out on beach nourishment projects as well as post nourishement studies to look at the sensitivity of the study areas to beach nourishment. The search was focused using the habitats as identified in each of the study beaches and the potential impact on these. This is a follow up to the 2009/10 beach nourishement pilot study and the Phase 2 project report that looked at the practicalities of rebuilding beaches. |
