The Mid-Range Future Scenario (MRFS) flood extents represent a projected future scenario for the year 2100 and Any combination of storage areas result in partial protection to properties and some hard defences (with an average and maximum height of 0.9m and 1.9m respectively) are still required to protect to the 1% AEP fluvial flood event. The second location would consist of 139m of flood embankment 0.8m high (average). in erosion and recession, beach levels/volume, foreshore features, etc. This means that areas may be shown to flood, even though at present a flood The improvement of channel conveyance consists of the removal of a weir on the Ballynerin watercourse. This scheme is intended to facilitate a community based response to flood events by improving the resilience and preparedness of the local community. individual properties or point locations, or to replace a detailed local erosion hazard and risk assessment. The survey data should not be published by you, without prior written approval from OPW. The Scheme, which comprises, construction of hard defences (embankments & flood walls), culvert removal and the upgrade of three access bridges, is expected to provide protection against an estimated 100-Year fluvial flood (1% Annual Exceedance Probability) and a 200-Year flood (0.5% Annual Exceedance Probability) tidal event for 61 properties. The potential effects of climate change have been separately modelled and reported on. Two weirs would be removed on the Nuenna River (02WEIR02 at Chainage 1227 and 03WEIR01 and Chainage 1240).

The proposed measure consists of building hard defences, at risk properties would be protected by a series of flood embankments and walls set back where possible from the river channel allowing the floodplain function to remain active. The flood extents were made using remote sensing images (Copernicus Programme Sentinel-1), which covered any site in Ireland every 4-6 days. areas may be shown to flood, even though at present a flood defence is protecting them. The Spencer Dock Flood Relief Scheme was initiated in 2006 following major flooding in 2000, and was constructed from 2007 to 2009. The survey commenced in mid-September 2003 and was completed in 11 days. The Bandon River (Dunmanway) Drainage Scheme was initiated in 1990 following major flooding in 1986, and was constructed from 2000 to 2002. over 1m). mapping only takes into account coastal flooding from a combination of tide levels and storm surges; any significant The proposed measure for Avoca AFA that may be implemented after project-level assessment and planning or Exhibition and confirmation might include physical works, such as a series of hard defences (flood embankments and walls) along with improvement of channel conveyance on a tributary. Major flooding is occurring at Wollombi in the Hunter Valley, while moderate flooding is still plaguing Taree and Gloucester. Expand this section to see community/afa level measures at the selected location. It is currently at preliminary design stage, and is expected to go to planning in 2018. The structure would consist of a set of gates which could be closed after a flood warning, and open during normal conditions to allow the passage of boats. In addition, the flood extent This scheme was undertaken by the OPW and is maintained as part of current duties. The proposed measure consists of storage and a series of flood embankments and walls. This document shall be governed by, and construed in accordance with, the laws of Ireland and you agree to the exclusive jurisdiction of the Courts of Ireland. Demountable flood gates will also be required to maintain access. It is important for the avoidance of increased flood risk that this infrastructure is operated according to the relevant regulations and is maintained in good working order into the future. The Carrigaline Flood Relief Scheme has been under review to confirm the technical aspects and viability, and, subject to outcomes, will then progress to Outline Design and Planning.

Vertical Sector Gate to act as a barrier to flooding across the entrance to Portumna Harbour to prevent the inlet receiving flood water directly from the Shannon. These hard defences would protect properties from the 1% AEP fluvial event and the 0.5% AEP coastal event with an estimated average height of 1.7m and a total length of 870m. defence works potentially protecting the coastal floodplain are not taken into account. Construction was undertaken within three local authority areas Meath, Fingal and Dublin City. Full details are available here. These hard defences will provide an SoP of 1% AEP for fluvial flood events and 0.5% for coastal flood events, at a total length of 1.3km and an average height of 1m. The Scheme, comprised channel widening and deepening along the Shinkeen stream and provides protection against a 100-Year fluvial flood (1% Annual Exceedance Probability) for 26 properties. The North City Pluvial Flood Alleviation Project was initiated in October 2008 following major pluvial flooding earlier that year and continued after another significant thunderstorm event in July 2009. only takes into account coastal flooding from a combination of tide levels and storm surges; any significant impact Modelled extent of land that might be directly flooded by rainfall in a severe rainfall event. T tuilleadh faisnise ar fil maidir le Amharcir Sonra Tuilte Screamhuisce SG. The fluvial Hard Defences and the Pumping Station would both need to be in place to achieve full protection from a 1% AEP fluvial event. An allowance of -0.5mm/year for GIA was included for the southern part of the national coastline only (Dublin to Galway and south of this). In March 2017, Tipperary County Council secured further funding via OPW's minor works programme to reduce the risk of flooding to 14 properties. and along the left bank of the Mayne River and tributary is expected to provide protection against an estimated 100-Year fluvial flood (1% Annual Exceedance Probability) for 20 properties. The proposed measure consists of a series of flood walls to protect to the standard of a 1% AEP fluvial flood event. The Flood Point symbol marks the approximate location of a past flood. The Channels layer identifies the watercourses forming part of Arterial Drainage Schemes. Full details are available here. The following table sets out the range of flood event probabilities for which coastal flood extent maps were developed, expressed in terms of Annual Exceedance Probability (AEP), and identifies their parallels under other forms of expression. At risk properties would also be protected by installing a trash screen upstream of a bridge which is susceptible to blockage. A detailed geotechnical structural and stability assessment of the existing embankments was not undertaken as part of the CFRAM study, but should be undertaken as part of the project-level assessment in progressing this measure. We welcome information on recent or past flood events including supporting documentation, which can be submitted by using the that were included in Phase 3 of the Irish Coastal Wave and Water Level Modelling Study (ICWWS 2018) and from further Coastal Wave and Water Level Modelling Studies (CWWS) The Scheme, that provides protection to the 1 in 100 year Standard of Protection against flooding from the Griffeen River, comprised of: a) the lowering of the river bedrock in Lucan Village, b) the lowering of the horseshoe weir at Vesey Bridge, c) repointing and raising height of masonry pillars, and d) repointing and raising height of wall in Main Street Lucan. 525 de 2015) agus c go spreagtar athsid na faisnise, glacann t leis nr cheart duit an Larscili Tscach Abhann Nisinta n aon bhar eile ar an Suomh Grasin a sid le haghaidh aon ghnomhaochta a ghineann ioncam trchtla, gn, gairmiil n eile. Land use management would be assessed to identify land use features that would reduce surface water runoff. This option involves rehabilitating (i.e. Move mouse over station for more data. The proposed measure for Lucan to Chapelizod that may be implemented after project-level assessment and planning or Exhibition and confirmation might include physical works, such as a series of hard defences (flood embankments and walls). None of the methods were found to be economically viable. These areas were divided into one or more map tiles depending on area, and maps were produced for each tile. Where the boundary of a flood has been mapped, the flood is shown as a shaded area with a blue border defining the extent of the flood. Construction 1,799m of new flood defence walls, 846m of new embankments and a 2m floodgate. The Fermoy Flood Relief Scheme was initiated in 2002 and it was decided to implement the scheme on a phased basis.

These hard defences would protect to the 1% AEP flood event with an average height of 0.9m and a total length of 2.4km. A flood relief scheme has been implemented for Kilkenny (Nore) AFA, and is maintained by the OPW. The following table sets out a range of flood event probabilities for which fluvial and coastal flood maps are typically developed, expressed in terms of Annual Exceedance Probability (AEP), and identifies their parallels under other forms of expression. The floods are shown as polygons. Construction a flapped outfall unit for the watercourse that passes through the embankment to prevent reverse flow from the River Shannon. The Scheme, which comprises construction of demountable flood defences at the underpass along with localised embankments is expected to provide protection against an estimated 100-Year flood (1% Annual Exceedance Probability) in the fluvial region and the 200-Year flood (0.5% Annual Exceedance Probability) tidal event for 37 properties. High resolution forecasts are available at Galway Bay and, as part of a coastal flood forecasting system for Galway Bay, could be used to provide warning to the residents of Kinvarra. The Scheme, that comprises of flood defence gates for the doorways of individual properties, reduces the risk of internal flooding from the Deel River for 76 properties. Daily readings of temperature and rainfall over the past three months from all Australian Bureau of Meteorology weather stations High resolution forecasts are available at Galway Bay and, as part of a coastal flood forecasting system for Galway Bay, could be used to provide warning to the residents of Roundstone. Flood defences were previously built to protect properties in the community of Tower / Blarney. The Scheme, which comprises flood defence walls and embankments along the River Barrow and Burren Stream with a pumping station at their confluence, provides protection against a 100-Year flood (1% Annual Exceedance Probability) for 185 properties. Local authorities are charged with responsibility to maintain Drainage Districts. The Present Day Scenario is referred to as the Current Scenario in the maps and reports. They may, however, also be of use to the public, Local Authorities and other parties as indicative maps of flood-prone and erosion-prone areas for a range of purposes, including raising awareness of flood and erosion hazard and risk, preparedness and response planning for flood and erosion events, assisting in planning and development decisions, etc. AFA scale flood relief works may be viable depending upon the findings of structural investigations into the performance of the existing river walls and the ability of the existing foundations to foot new or improved flood defence walls. The proposed flood defences would include sheet piles to counter the underground flow paths which exist between the river and flood receptors and consist of a series of flood embankments (average height of 1.25m and a total length of 667m) and retaining walls (average height of 1.5m and a total length of 300m).
