Title

Map based index (GeoIndex) geological indicators of flooding

Abstract

This layer of the map based index (GeoIndex) shows where river floodplains and coastal plains in Britain are located and therefore the main areas at greatest risk of flooding. The map shows areas vulnerable to two main types of flooding: inland (river floodplains) and coastal/estuarine and is therefore a key tool in identifying those areas most vulnerable from future flooding. The map is based on observation of the types of geological deposit present and does not take into account any man-made influences such as house building or flood protection schemes. It also does not take into account low-lying areas where flooding could occur but where there are no materials indicating flooding in the geological past. The BGS Geological Indicators of Flooding data should therefore be regarded as complementary to, but not a replacement for, existing Environment Agency flood risk maps. The BGS Geological Indicators of Flooding (GIF) dataset is a digital map based on the BGS Digital Geological Map of Great Britain at the 1:50,000 scale.

Lineage

The BGS Geological Indicators of Flooding (GIF) dataset is a digital map based on the BGS Digital Geological Map of Great Britain at the 1:50,000 scale. It was produced by characterising Superficial Deposits on DiGMapGB-50 in terms of their likely vulnerability to flooding, either from coastal or inland water flow.

Constraints related to access and use

Constraint set

Use constraints

Either: (i) the dataset is made freely available, e.g. via the Internet, for a restricted category of use (e.g. educational use only); or (ii) the dataset has not been formally approved by BGS for access and use by external clients under licence, but its use may be permitted under alternative formal arrangements; or (iii) the dataset contains 3rd party data or information obtained by BGS under terms and conditions that must be consulted in order to determine the permitted usage of the dataset. Refer to the BGS staff member responsible for the creation of the dataset if further advice is required. He / she should be familiar with the composition of the dataset, particularly with regard to 3rd party IPR contained in it, and any resultant use restrictions. This staff member should revert to the IPR Section (ipr@bgs.ac.uk) for advice, should the position not be clear.
