Details
To support the work of Thames Estuary 2100 (TE2100), the Environment Agency publishes datasets. Current datasets include:
- policy unit boundaries
- flood storage areas
- extreme water level nodes
- London boroughs - electoral and administrative boundaries
- spatial flood defences
- flood map for planning
- historic flood map

Policy unit boundaries: Thames Estuary 2100
The Thames Estuary is divided into 23 geographical areas, known as policy units, to decide on the appropriate level of flood risk management. This dataset shows each policy unit’s boundaries.
Flood storage areas: Thames Estuary 2100
This dataset shows the 4 potential flood storage areas identified in the Thames Estuary 2100 Plan as one of the options to manage future flood risk. These storage areas could receive and store tidal flood flows during large storm surge events. They would help to reduce extreme flood levels and prevent flooding further upstream.
Extreme water level nodes: Thames Estuary 2100
This dataset shows extreme water level nodes in the Thames Estuary. Extreme water level nodes show the point locations of modelled data projections for extreme water levels (heights) that could occur in the Thames Estuary in the future. These are used to inform flood defence design.
London boroughs
This dataset contains all levels of electoral and administrative boundaries, from district, wards and civil parishes (or communities) to parliamentary and assembly constituencies.
AIMS spatial flood defences
This dataset shows the owners and maintainers of all flood defences in England:
- Environment Agency
- local authorities
- individuals
- companies
- charities
- any with unknown ownership
Flood map for planning (rivers and sea) - flood zone 2
This dataset covers flood zone 2, which shows a 0.1% or higher chance of flooding each year. It estimates areas of land at risk of flooding, to support flood risk assessments in line with planning practice guidance. This dataset does not take into account the presence of defences.
Historic flood map
This dataset shows the areas of land in England that have previously been flooded.
