Coastal landfill shoreline management implications

项目摘要

Our coastlines need to be managed into the future taking into account the effect of climate change on rising sea levels, whilst balancing public investment and benefits. There is a strong desire to move to more sustainable shoreline management, which allows coasts to be more dynamic in less developed coastal areas. Rather than rigidly defending and holding the existing coastline, shoreline management plans now consider the benefits of "managed realignment" and "no active intervention" policies. However, there is an important legacy of hundreds of coastal landfills located in flood plains around our coasts, including estuaries. This constrains a dynamic policy for shoreline management as storms and rising sea levels may lead to increased flushing of contaminants into the environment and erosion of the landfill may result in the direct exposure and release of potentially hazardous waste. It raises the question about the ability to move/process these landfills (facilitating a move to more dynamic coasts), or alternatively to continue to protect these sites under rising sea levels, potentially creating a lock-in to defence infrastructure approaches.This project aims to apply NERC-funded and other relevant research at the University of Southampton, together with CIRIA generic guidance C718 on "Guidance on the management of landfill sites and land contamination on eroding or low-lying coastlines", to better understand the effective long-term management of coastal-located waste sites on dynamic coasts. In the context of shoreline management planning it will assess a series of different management approaches that have the potential to address the difficulties that coastal landfills pose. We will identify 3 to 4 coastal landfills from Lyme Regis to Shoreham and consider their impact on three shoreline management plan strategic options (hold the line, managed realignment, and no active intervention) for two different climate change scenarios. Pollution risks arising from the dual hazards of flooding, leading to the release of contaminated water (leachate), and erosion of the landfills will be considered along with the potential for resource recovery from the old site in any options that involve moving and/or remediating the waste in situ. Our project partners are the Environment Agency, SCOPAC (Standing Conference on Problems Associated with the Coastline) which is an influential network of local authorities and organisations with an interest in the management of the coast of central southern England, the Eastern Solent Coastal Partnership and the Channel Coastal Observatory hosted by New Forest District Council.Keywords: Shoreline Management, climate change, sea level rise, flooding, landfill

我们的海岸线需要在未来进行管理，考虑到气候变化对海平面上升的影响，同时平衡公共投资和效益。人们强烈希望转向更可持续的海岸线管理，从而使欠发达沿海地区的海岸更具活力。海岸线管理计划现在考虑的是“有管理的调整”和“不积极干预”政策的好处，而不是严格捍卫和控制现有海岸线。然而，位于我们海岸（包括河口）周围洪泛区的数百个沿海垃圾填埋场留下了重要的遗产。这限制了海岸线管理的动态政策，因为风暴和海平面上升可能导致污染物更多地冲入环境，而垃圾填埋场的侵蚀可能导致潜在危险废物的直接暴露和释放。它提出了关于移动/处理这些垃圾填埋场（促进向更有活力的海岸移动）的能力的问题，或者在海平面上升的情况下继续保护这些地点的能力，这可能会锁定国防基础设施方法。该项目旨在应用 NERC 资助的南安普顿大学的其他相关研究，以及 CIRIA 通用指南 C718 关于“垃圾填埋场和土地管理指南” 侵蚀或低洼海岸线的污染”，以更好地了解动态海岸沿海废物场的有效长期管理。在海岸线管理规划的背景下，它将评估一系列不同的管理方法，这些方法有可能解决沿海垃圾填埋场带来的困难。我们将确定从莱姆里吉斯到肖勒姆的 3 到 4 个沿海垃圾填埋场，并考虑它们对两种不同气候变化情景下的三种海岸线管理计划战略选项（坚守阵地、有管理的重新调整和不积极干预）的影响。在涉及就地移动和/或修复废物的任何方案中，将考虑由洪水双重危害引起的污染风险，导致污染水（渗滤液）的释放和垃圾填埋场的侵蚀，以及从旧场地回收资源的潜力。我们的项目合作伙伴包括环境署、SCOPAC（海岸线相关问题常设会议）（这是一个由对英格兰中南部海岸管理感兴趣的地方当局和组织组成的有影响力的网络）、东索伦特海岸伙伴关系和由新森林区议会主办的英吉利海峡沿海观测站。关键词：海岸线管理、气候变化、海平面上升、洪水、垃圾填埋场
