TE2100 Floodplain Management - Environment Agency - Thames Region

This Study forms part of the Environment Agency’s Thames Estuary 2100 Project (TE2100) which is exploring a range of options for an integrated and adaptable approach to managing flood risk in the Thames Estuary now and in the future.

The ‘Floodplain Management Measures’ approach reduces the consequences of flooding through a set of actions which are often called ‘Receptor Responses’. Those people and assets at risk of flooding are referred to as ‘Receptors’ and the term ‘Receptor Response’ relates to actions that can be taken to reduce the risks by individuals, authorities and others. These actions include measures such as improving the resilience of buildings and transport services infrastructure; improving awareness and preparedness; improving emergency planning and the response by local authorities and the emergency services; and locating vulnerable developments in areas with the lowest likelihood of flooding.

Maslen Environmental have developed a set of maps which show, for the Thames Estuary, where ‘Floodplain Management Measures’ could feasibly reduce risk. The maps provide the basis for engagement with stakeholders and other interested parties about the ‘Floodplain Management Measures’ approach and will assist in setting priorities and raising issues and concerns.

Alongside the ‘Floodplain Management Measures’ Maps, Maslens have also carried out Event Tree Analysis (ETA) to assess the effectiveness of measures both in terms of reduction in risk to life and economic damages. As part of this analysis ‘best case’ risk reduction factors (RRFs) have been developed to predict what is potentially possible, over a series of future time epochs, with the input of major investment in ‘Floodplain Management Measures’. The potential costs of taking a Floodplain Management Measures approach were also examined as part of a wider review on the performance of Floodplain Management Measures.

The techniques and experitise built up through carrying out this and several other projects for the Environment Agency as part of their TE2100 project are currently being used by us to carry out a ‘Floodplain Management Measures’ study for the Environment Agency within the Humber Flood Risk Management Strategy area.
