The European Copernicus Coastal Flood Awareness System (ECFAS) project aimed at contributing to the evolution of the Copernicus Emergency Management Service (https://emergency.copernicus.eu/) by demonstrating the technical and operational feasibility of a European Coastal Flood Awareness System. Specifically, ECFAS provides a much-needed solution to bolster coastal resilience to climate risk and reduce population and infrastructure exposure by monitoring and supporting disaster preparedness, two factors that are fundamental to damage prevention and recovery if a storm hits.

The ECFAS Proof-of-Concept development ran from January 2021 to December 2022. The ECFAS project was a collaboration between Scuola Universitaria Superiore IUSS di Pavia (Italy, ECFAS Coordinator), Mercator Ocean International (France), Planetek Hellas (Greece), Collecte Localisation Satellites (France), Consorzio Futuro in Ricerca (Italy), Universitat Politecnica de Valencia (Spain), University of the Aegean (Greece), and EurOcean (Portugal), and was funded by the European Commission H2020 Framework Programme within the call LC-SPACE-18-EO-2020 - Copernicus evolution: research activities in support of the evolution of the Copernicus services.

Description of the Dataset

The present database gathers flood and velocity maps for the European Union coast as well as their associated forcing parameters. The coast is divided into geographic regions embracing similar oceanographic conditions and subsequently into coastal sectors. The coastal sectors can be identified by its region index RXXX and its own index CSYYY. For each coastal sector, flood models were developed using the LISFLOOD-FP model with a grid resolution of 100 m. The flood model configuration follows the recommendation highlighted in ECFAS Deliverable D5.2 - Validated LISFLOOD-FP model for coastal areas. The flood and velocity maps are associated with synthetic storms that are characterised by a specific extreme water level and storm duration. These parameters were derived from Extreme Value Analyses performed on the ECFAS ANYEU-SSL hindcast (ECFAS D4.1 - Report on the calibration and validation of hindcasts and forecasts of TWL and D4.3 - Report on the identification of local thresholds of TWL for triggering coastal flooding). Five extreme water level values for each coastal point of the hindcast, and three durations (12, 24 and 36 h) were identified leading to 15 scenarios for each coastal sector. The flood and velocity maps are gathered into a NetCDF file for each coastal sector indicating the scenario parameters as attributes. In addition, the extreme water level values used for each coastal sector are contained in a complementary NetCDF file.

The shapefile of the polygons defining the coastal sectors as defined for the catalogue implementation is included in the database.

Flood Risk Areas:This metadata record is for Approval for Access product AfA256. Flood Risk Areas identify locations where there is believed to be significant flood risk. The EU Floods Directive refers to Flood Risk Areas as 'Areas of Potentially Significant Flood Risk' (APSFR). Flood Risk Areas have been defined by the Environment Agency (main rivers and the sea) and Lead Local Flood Authorities (surface water). Other sources of flooding are not covered. This dataset includes Flood Risk Areas defined for both Cycle 1 (December 2011) and Cycle 2 (December 2018). The criteria used to determine significance are explained in supporting guidance document supplied with this data. Flood Risk Areas determine where Flood Hazard and Risk Maps and Flood Risk Management Plans must subsequently be produced to meet obligations under the EU Floods Directive. INFORMATION WARNING Flood Risk Areas are designed to meet the needs of the European Floods Directive. They are designed for broad planning purposes only and are not appropriate for any other type of flood mapping. Other flood mapping is available which is more appropriate to showing localised flood risk.Flood Warning Areas:This record is for Approval for Access product AfA054 Flood Warning Areas. These are geographical areas where we expect flooding to occur and where we provide a Flood Warning Service. They generally contain properties that are expected to flood from rivers or the sea and in some areas, from groundwater. Specifically, Flood Warning Areas define locations within the Flood Warning Service Limit that represent a discrete community at risk of flooding.Flood Warnings are issued when flooding is expected to occur, Severe Flood Warnings are issued to similar areas when there is a danger to life or widespread disruption is expected.INFORMATION WARNING: Groundwater flood warning areas are property based, usually containing a discrete urban area, suburb, city, village, or hamlet and were created in various ways. In general specialists used the national groundwater dataset, historical maps, bedrock geology and records of properties affected by groundwater flooding in the past to create the groundwater flood warning areas. Additional data sources, including groundwater susceptibility maps, borehole data, local modelling and LiDAR may also have been used depending on the location of the area.Flood Warning Areas can be created, amended, or deleted at certain times in the year. This dataset was last updated on:20th November 2024The scheduled updates where changes may be introduced are:21st February 202422nd May 2024 - due to the ongoing flooding, this was postponed until June 5th14th August 2024 and20th November 2024Please note that these dates may change at short notice if there are system issues or a large-scale flood event.Flood Alert Areas:This record is for Approval for Access product AfA055. Flood Alert Areas are geographical areas where it is possible for flooding of low-lying land and roads to occur from rivers, sea and in some locations groundwater. A single Flood Alert Area may cover the floodplain within the Flood Warning Service Limit of multiple catchments of similar characteristics. A Flood Alert Area may contain one or more Flood Warning Areas. In some coastal locations a Flood Alert may be issued for spray or overtopping and be defined by a stretch of coastline.A Flood Alert is issued to warn people of the possibility of flooding and encourage them to be alert, stay vigilant and make early / low impact preparations for flooding. Flood Alerts are issued earlier than Flood Warnings to provide advance notice of the possibility of flooding and may be issued when there is less confidence that flooding will occur in a Food Warning Area. Flood Warnings Areas (established to apply to discrete communities) are available in AfA054.INFORMATION WARNING: The groundwater flood alert areas are either at a community/local scale, or where this is not possible are more generalised and based on other factors, such as geology and counties. In general, specialists used the national groundwater dataset to make a comparison with historical maps and bedrock geology to create the groundwater flood alert areas. Additional data sources, including groundwater susceptibility maps, borehole data, local modelling and LiDAR may also have been used depending on the location of the area.Flood Alert Areas can be created, amended, or deleted at certain times in the year. This dataset was last updated on:November 20th 2024The scheduled updates where changes may be introduced are:21st February 202422nd May 2024 - Due to the ongoing flooding, this was postponed until June 5th14th August 2024 and20th November 2024Please note that these dates may change at short notice if there are system issues or a large-scale flood event.

Description of the files contained in the Dataset

The ECFAS Pan-EU Impact Catalogue collects impact layers associated to the flood scenarios contained in the ECFAS Pan-EU Flood Catalogue. To produce the Flood Catalogue, the coast was divided into geographic regions embracing similar oceanographic conditions, and subsequently into coastal sectors. The coastal sectors can be identified by its region index RXXX and its own index CSYYY. Impacts associated to the flood maps were calculated following the approach described in the technical document of the ECFAS Deliverable 5.3 Algorithms for Impact Assessment (ECFAS Impact Tool; Duo et al., 2021). The ECFAS Impact Tool was adapted to assess the affected population, the damage to buildings, roads and railways and the exposure of a variety of other assets (e.g. agriculture, points of interest, etc.) for the flood scenarios included in the ECFAS Flood Catalogue.

The shapefile of the polygons defining the coastal sectors as defined for the catalogue implementation is included in the database.

Table listing flood maps produced on the IRR, produced for reporting purposes for the European Flood Directive.European Directive 2007/60/EC of 23 October 2007 on the assessment and management of flood risks (OJ L 288, 06-11-2007, p. 27) influences the flood prevention strategy in Europe. It requires the production of flood risk management plans aimed at reducing the negative consequences of flooding on human health, the environment, cultural heritage and economic activity.The objectives and requirements for implementation are set out in the Law of 12 July 2010 on a national commitment for the environment (LENE) and the decree of 2 March 2011. In this context, the primary objective of flood and flood risk mapping for IRRs is to contribute, by homogenising and objectivating knowledge of flood exposure, to the development of flood risk management plans (PGRIs).This dataset is used to produce flood surface maps and flood risk maps, respectively, representing flood hazards and issues exposed on an appropriate scale. Their aim is to provide quantitative evidence to better assess the vulnerability of a territory for the four levels of flood probability (high, medium, medium, low).

Since November 26, 2007, the EU's "Guideline on the Assessment and Management of Flood Risks" (FD) has been in force. The aim of the Flood Directive is to provide a framework for assessing and managing flood risks to reduce the adverse impacts of floods on human health, the environment, cultural heritage and economic activities in the community. The FD thus pursues the purpose of reducing flood risks and improving flood prevention and risk management through coordinated cross-border flood protection in the river basin districts, including coastal areas. The implementation is intended to improve the self-sufficiency of the municipalities and the affected citizens. The first reporting cycle ended with the preliminary assessment of the flood risk and determination of the areas where it can be assumed that "a potentially significant flood risk exists or can be considered likely" (Art. 4 and 5) by 22.12.2011, the preparation of the Flood hazard and flood risk maps (Art. 6) by December 22, 2013 and the development of the flood risk management plans (Art. 7) by December 22, 2015. According to Article 14 of the Floods Directive, in the second reporting cycle - the preliminary assessment of the flood risk or the assessment and decisions pursuant to Article 13 (1) by December 22nd, 2018, - the flood hazard maps and the flood risk maps by December 22nd, 2019 and - the flood risk management plans, including the components described in Part B of the Annex, reviewed and updated as necessary by 22/12/2021 and every six years thereafter. The reviews will take into account the likely impact of climate change on flood occurrence. The results are to be submitted to the EU Commission within three months of the specified dates by March 22nd. to be made available for the following year. The flood hazard maps according to Art. 6 Para. 3 WFD cover the geographical areas that could be flooded according to the following scenarios: 1. Floods with a low probability or scenarios for extreme events; 2. Flood with medium probability; 3. If applicable, high probability of flooding. The flood hazard maps indicate for the individual scenarios (paragraph 4): 1. Extent of flooding; 2. Water depth or, if applicable, water level. For coastal areas that are already adequately protected (paragraph 6), the creation of flood hazard maps can be limited to one extreme event. In SH, the three flood scenarios mentioned above are also presented in all other areas that are not adequately protected. Flood risk maps are created on the basis of the flood hazard maps for the same flood scenarios. In addition to the flood hazards (extent and depth of flooding), the flood-related adverse effects (significance criteria) are to be presented in them. The required information is listed in Article 6(5) of the FWD: 1. Number of potentially affected residents, 2. Type of economic activities in the potentially affected area, 3. Installations of Directive 2010/75/EU on industrial emissions (IED) and potentially affected protected areas according to Annex IV, point 1, points i, iii and v of Directive 2000/60/EC 4. other information that the Member State considers useful, such as the indication of areas where floods with a high content of entrained sediments and Debris-carrying floods can occur, and information on other significant sources of pollution. Note on the data For a complete picture of flood risks, these two datasets should be considered: - Coastal Flood - River Flood - this dataset The ArcMap projects (mxd files) are stored in provided with version 10.2. Please note the instructions for use and description of the data.

A series of spatial data produced by the SGI High Flood Risk Land Flood Directive (TRI) of Meaux and mapped for reporting purposes for the European Flood Directive. European Directive 2007/60/EC of 23 October 2007 on the assessment and management of flood risks (OJ L 288, 06-11-2007, p. 27) influences the flood prevention strategy in Europe. It requires the production of flood risk management plans to reduce the negative consequences of flooding on human health, the environment, cultural heritage and economic activity.

In this context, the primary objective of flood and flood risk mapping for IRRs is to contribute, by homogenising and objectivating knowledge of flood exposure, to the development of flood risk management plans (WRMs). This dataset is used to produce flood surface maps and flood risk maps that represent flood hazards and issues at an appropriate scale, respectively. Their objective is to provide quantitative evidence to further assess the vulnerability of a territory for the three levels of probability of flooding (high, medium, low).

The map depicts flood prone areas in Europe for flood events with 10-year return period. Cell values indicate water depth (in m). The map can be used to assess flood exposure and risk of population and assets

This dataset contains fluvial flood maps of the present day 1 in 20 year return period, and corresponding flood extents for 3 SSP (Shared Socioeconomic Pathway)/RCP(Representative Concentration Pathway) scenarios for the future (2070-2100). Change in flood return periods are estimated using CMIP6 projections and subsequently used to extract flood maps from a global flood model. Full details about this dataset can be found at https://doi.org/10.5285/0d5d69ae-7f50-40ee-a0c9-2522de138f27

This map shows the annual average economic damage of flooding from the sea in the current climate. The economic risk is calculated as a weighted combination of the 3 economic damage maps with high, medium and low probability, expressed in €/m²/year.

This map shows the areas where there is a risk of flooding (high, medium and low probability) due to flooding from the sea, rivers and intense precipitation. These maps were drawn up on the basis of modeling and used in the Preliminary Flood Risk Assessment in the context of the European Flood Directive.

A series of spatial data produced by the GIS High Flood Risk Land Flood Directive (TRI) of the French Metropolis and mapped for reporting purposes for the European Flood Directive.

The following probabilities are available for coastal flooding: - High - 10 year return period - Medium - 200 year return period - Low - 1000 year return period and 200 year return period plus climate change using the UKCP09 high emissions scenario for the 2080s.The coastal hazard maps show (where available): - Flood extent - Flood depth's where appropriate. The climate change scenario has been defined by United Kingdom Climate Projection 2009 (UKCP09) predictions for 2080 high emissions 95%ile predictions. Medium and low probability flood events were selected for consistency with return periods used in Scottish Planning Policy, whereas the high probability was chosen as it is reflective of observed events experienced over the last few decades

The National Flood Hazard and Risk Maps are based on generalised modelling only. The maps have been published to comply with the Flood Risk Regulations (2009) and the EU Directive (2007/60/EC), and used to inform the creation of Flood Risk Management plans across Wales. These maps have no official status for Planning or Insurance purposes, therefore the public and professionals are advised to use the information contained within the Flood Risk Assessment Wales Map and Development Advice Map/ Flood Map for Planning (as appropriate) for these purposes as these will be more up-to-date and incorporate improved modelling information. The National Flood Risk Maps have been created for 3 sources of flooding, namely, 1. Flooding from Rivers 2. Flooding from the Sea 3. Flooding from Surface Water & Small Watercourse The maps show Risk to a range of receptors, grouped in categories of People, Economic and Environment. Risk information is aggregated and displayed at a community scale. For Rivers and Surface Water & Small Watercourses, High risk is up to 1 in 30year; Medium risk is between 1 in 30 and 1 in 100year; and Low risk is between 1 in 100year and 1 in 1,000year Annual Exceedance Probability (AEP). For the Sea, High risk is up to 1 in 30 year; Medium risk is between 1 in 30 to 1 in 200 year; and Low risk 1 in 200 year to 1 in 1000 year.

The Geostandard Flood Directive describes the basis of geographic data produced on the 120 territories at significant risk of flooding (TRI) and mapped for reporting purposes for the European Flood Directive. European Directive 2007/60/EC of 23 October 2007 on the assessment and management of flood risks (OJ 2007 L 288, 06-11-2007, p. 27) influences the flood prevention strategy in Europe by requiring the production of flood risk management plans on each river basin district. Article 1 of the Floods Directive sets out its objective of establishing a framework for the assessment and management of flood risks, which aims to reduce the negative consequences of flooding on human health, the environment, cultural heritage and economic activity. The objectives and requirements for achievement are given by the Law of 12 July 2010 on the National Commitment for the Environment (LENE) and the Decree of 2 March 2011. Within this framework, the primary objective of the mapping of flood areas and flood risks for IRRs is to contribute, by homogenising and objecting knowledge of the exposure of issues to floods, to the drafting of flood risk management plans (FRPs), to the definition of the objectives of this plan and to the development of local strategies by TRI. Thus, this Geostandard aims to: 1. homogenise the production of data used for flood area and flood hazard maps, 2. facilitate the implementation of GIS on each IRR. This GIS Flood Directive should become a living reference for knowledge of the hazards and risks of flooding on these IRRs and will be used to establish flood risk management plans. IRR SGIs will be integrated into a national common GIS.

This map shows the annual average social impact of flooding from the sea in future climate (with climate projection 2050). The social risk is calculated as a weighted combination of the 3 social damage maps with high, medium and low probability, expressed in a relative score/m²/year.

The European Directive 2007/60/EC of 23 October 2007 on the assessment and management of flood risks (OJ L 288, 06-11-2007, p. 27) influences the flood prevention strategy in Europe. It requires the production of flood risk management plans aimed at reducing the negative consequences of flooding on human health, the environment, cultural heritage and economic activity. The objectives and requirements for realignment are given by the Law of 12 July 2010 on the National Commitment for the Environment (LENE) and the Decree of 2 March 2011. In this context, the primary objective of the mapping of flood areas and flood risks for IRRs is to contribute, by homogehising and objecting knowledge of the exposure of issues to floods, to the development of flood risk management plans (FRPs). This series of data is used to produce the flood maps and the flood risk map that take the flood aleases and the stakes respectively expose to an appropriate scale. Their objective is to provide quantitative information to assess more finely the vulnerability of a territory for the three levels of probabilistic flooding (high, medium, low). The IRRs adopted in the context of the 1st cycle of the Flood Directive are defined as follows: Sort “Centre” Les Abymes — Baie-Mahault — Le Gosier — Le Moule — Morne-à-l’Eau — Pointe-à-Pitre — Sainte-Anne. Flooding by river overflow, storm runoff and marine submersion Sorting “Lower Earth — Baillif” Flooding by river overflow and storm runoff

River flood hazard maps for Europe and the Mediterranean Basin region is a gridded data set representing inundation along the river network, for nine different flood return periods (from 1-in-10-years to 1-in-500-years). The input river flow data for the new maps are produced by means of the open-source hydrological model LISFLOOD, while inundation simulations are performed with the hydrodynamic model LISFLOOD-FP. The extent comprises most of the geographical Europe and all the river basins entering the Mediterranean and Black Seas in the Caucasus, Middle East and Northern Africa countries. Flood hazard maps are generated for river basins > 150km2. Cell values indicate water depth (in m). The maps can be used to assess the exposure of population and economic assets to river floods, and to perform flood risk assessments. The dataset is created as part of the Copernicus Emergency Management Service. NOTE: this dataset is not an official flood hazard map (for details and limitations please refer to related publications).
