ABSTRACT
The Humber Estuary Shoreline Management Plan provides the framework for investment in defences to reduce the risk of flooding to people, property and the environment. A key issue is the rise in sea level, which is reducing the standard of protection provided and is increasing erosion. The plan is developed from detailed geomorphological and ecological studies, and extensive consultation with interested organisations and the community. It takes into account the urban and industrial development on the floodplain, high-grade agricultural land, the historic environment and the Humber's status as an outstanding site for wildlife, which is protected under the Habitats Directive. A key aim is wherever possible to work with natural processes. Another is to ensure that there is no net loss of protected inter-tidal habitat. The options investigated include changes to the existing alignment of the embankments. The overall strategy provides for a continuing line of defence around the estuary and tidal rivers but with the use of managed retreat in some places. The creation of new inter-tidal habitat by this means is to gain more stable and cost-effective defences, and to offset the loss of protected sites, including by coastal squeeze. Further studies are in progress to appraise potential managed retreat sites.
