National River Flow Archive time series of river flows measured at gauging stations throughout the United Kingdom, including peak flow (AMAX and POT data).
The National River Flow Archive is the primary archive of daily and peak river flows for the United Kingdom. The central archive comprises over 45,000 station-years of daily river flows and incorporates data from over 1400 gauging stations.
The NRFA comprises a number of datasets -
The General Quality Assessment (GQA) Headline Indicator Scheme (GQAHI) was the Environment Agency's national indicator for water quality in rivers and canals in England and Wales.
GQAHI was designed to provide an accurate and consistent assessment of the state of water quality and how it changes over time as a national picture. There three datasets are -
DARDNI monitors the levels of Lough Neagh and Louch Erne.
The Rivers Agency Hydrometric Section monitors water levels for rivers, sea and loughs at approximately 130 locations across Northern Ireland.
Some 80 gauging stations are situated in rivers, however, the most frequently requested levels are for Lough Neagh and Lough Erne, which are published online. The levels are monitored on a daily basis.
Information regarding the presence, and abundance, of benthic invertebrate species at specific marine monitoring points.
Only data from 2007 onwards is subject to NMBAQC quality assurance.
Supply format: Comma delimited.
Data availability: Available under the Open Government Licence (OGL).
Other conditions may apply and these are available via the download site.
Charge: No charge.
Sample available: Data can be downloaded immediately.
Flood Warnings are provided by the constant monitoring of stations and forecasting flooding from rivers or the sea. The live feed provides a summary of flood warnings (Alert Warning and Severe) that are sent externally. The Flood Warnings Live Feed provides current status update of every Flood Warning Area in England and Wales.
Supply format: tsv, json, xml
Datasets providing summary results for diatoms, invertebrates and macrophytes from samples taken for periods up to current year for England.
The three datasets are -
Released in July 2011, Land Cover Map 2007 (LCM2007) is the latest land cover map to be produced by the Centre for Ecology & Hydrology. It covers the whole of the UK.
Over the last 20 years, CEH has produced three digital land cover maps: LCMGB 1990, LCM2000 and LCM2007. Each of these land cover maps has been produced as a number of different products with varying data formats and spatial resolutions. All of the products of the three land cover maps can be obtained from CEH under licence for academic, non-commercial and commercial use.
A 50m grid interval DTM derived by the Centre for Ecology & Hydrology from 1:50,000 scale mapping from Ordnance Survey and Land & Property Services (previously OSNI). The IHDTM is comprised of five separate gridded datasets.
Each IHDTM grid is hydrologically consistent with the other IHDTM grids and with the CEH 1:50,000 Watercourse Network dataset.
The five gridded datasets are -
The Scottish Environment Protection Agency’s maps show where flooding may happen across Scotland so that individuals and groups can take appropriate action.
The available maps -
Flood Maps (NI) is an interactive map-viewer that enables users to access the latest flood hazard information available from government for the whole of Northern Ireland.
The map highlights the areas throughout Northern Ireland that are prone to flooding and its potential adverse impacts.
The map is designed to -
The Water Security Knowledge Exchange Portal supports the objectives of the UK Water Partnership - a collaboration between the water industry, policy and research communities. It provides guidance and co-ordination for water research and innovation in the UK.
