Flood Defence in the Blackwater Estuary, Essex, UK: The Impact of Sedimentological and Geochemical Changes on Salt Marsh Development in The Tollesbury Managed Realignment site

摘要

Recent changes in the UK's coastal defence strategy have resulted in the introduction of Managed Realignment (MR), a technique which attempts to establish salt mar- shes on low-lying coastal farmland. This work investigates the impact of MR, in particular on the interactions between sediment movement, changes in heavy metal concentrations and salt marsh development. Pre-and post- inundation samples were collected and analysed between 1995 and 1997.
