This report was produced by the University of Southampton Waste Management Research Group and Energy and Climate Change Group as part of a study for the “Coastal landfill and shoreline management: implications for coastal adaptation infrastructure” project" funded by the Natural Environment Research Council (NERC: NE/N012909/1) as part of the Environmental Risks to Infrastructure Innovation Programme. The report details results from a study on a site known as Pennington Marshes, near Lymington on the south coast of England. The landfill site lies behind a sea defence wall and the shoreline management plan for the coastal stretch fronting the landfill is to hold the existing defence line (HTL). Flooding has already occurred at Pennington (in 1989), and modelling carried out during the study showed that there is an increased risk of inundation of the landfill especially under high sea level rise conditions. To prevent flooding and potentially erosion of the landfill in the long term, increases in seawall elevation are needed to provide the same level of protection as it currently provides (1 in 50 year). The study also explored other options such as removing the landfill, or the potential for 'managed realignment' at the site: i.e. realigning the sea defences to allow the development of a much larger intertidal area and adding a new sea wall to protect the Pennington Marshes landfill.

Abstract

This report was produced by the University of Southampton Waste Management Research Group and Energy and Climate Change Group as part of a study for the “Coastal landfill and shoreline management: implications for coastal adaptation infrastructure” project" funded by the Natural Environment Research Council (NERC: NE/N012909/1) as part of the Environmental Risks to Infrastructure Innovation Programme. The report details results from a study on a site known as Pennington Marshes, near Lymington on the south coast of England. The landfill site lies behind a sea defence wall and the shoreline management plan for the coastal stretch fronting the landfill is to hold the existing defence line (HTL). Flooding has already occurred at Pennington (in 1989), and modelling carried out during the study showed that there is an increased risk of inundation of the landfill especially under high sea level rise conditions. To prevent flooding and potentially erosion of the landfill in the long term, increases in seawall elevation are needed to provide the same level of protection as it currently provides (1 in 50 year). The study also explored other options such as removing the landfill, or the potential for 'managed realignment' at the site: i.e. realigning the sea defences to allow the development of a much larger intertidal area and adding a new sea wall to protect the Pennington Marshes landfill.
