This layer shows the modelled extent of land that might be flooded by the sea in a very extreme flood event. The Raheny (Santry River) Flood Protection Project was initiated following major fluvial flooding in 1986, 2008, 2009 and 2011, and a first phase was constructed in 2013. The proposed measure relies on ood protection being provided by some existing embankments that were constructed to provide protection to agricultural land, and that were not constructed to the modern engineering standards that would be applied now when providing urban ood protection. The potential effects of climate change have been separately modelled and reported on. The Brosna (Westmeath, Offaly and Laois) was the first scheme, which commenced in 1947. Part IV of the Arterial Drainage Act, 1945 created a provision for embankments to be absorbed into drainage schemes. When combined these works provide protection against a 100-Year flood (1% Annual Exceedance Probability) for 18 properties. The properties in the Claddagh area, along Grattan road and Father Griffin would be provided protection by building a quay wall along the Claddagh basin and Nimmo's pier. River flooding is referred to as Fluvial flooding in the Maps and Plans. A 125m length of road would also have to be raised. The upgraded culvert would contain the flow of 1% AEP fluvial event within the Mullatee watercourse.

These embankments were created by landowners to reclaim land from rivers or the sea, typically in the 19th century. Rivers , lakes weirs and bridges were modified to enhance conveyance, embankments were built to control the movement of flood water and various other work was carried out under Part II of the Arterial Drainage Act, 1945. Some of these schemes have involved private elements. The proposed measure for Newbridge 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), four new or upgraded trash screens tanking two existing properties and works to improve channel conveyance including dredging 90m of the Doorfield tributary and upgrading two culverts. The hard defences have an average height of 1m and a total length of 0.3km. Professional or specialist advice should be sought before taking, or refraining from, any action on the basis of the National Indicative Fluvial Mapping or the Website content. 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. exceeded in any given year.

The Department of Housing, Planning & Local Government (DHPLG) is researching how Community Resilience may be advanced as part of the overall review of the Framework of Major Emergency Management. These works were undertaken by Limerick City Council with funding from the OPW and are maintained under Local Authority duties. The benefit of each scheme is assessed on its merits and not all schemes can reach the level of protecting buildings (mainly dwellings) to the 1% AEP level. Project Period: 2005 2013. In addition, the flood extent mapping only takes into Equally, there may be an erosion line Earth embankments from the excavated channel will be created on the lower side of the channels to provide freeboard and prevent overtopping. Brisbane River at Brisbane City has just reached the major flood level (3.50m) on the high tide," BOM said. The average height of these embankments is 0.6m and provides protection up to the 1% AEP fluvial event and 0.5% AEP tidal event. On 11 April 2017, the Government agreed the administrative arrangements for a once-off Homeowners Voluntary Relocation Scheme for those primary residential properties that flooded during 4 December 2015 to 13 January 2016. This includes a freeboard allowance of 0.3m. Construction 1,799m of new flood defence walls, 846m of new embankments and a 2m floodgate.

The next step is to appoint a service provider in 2018 to review the CFRAM outputs and see if local options may be possible to reduce flood risk for approximatey 570 properties estimated to be at flood risk in a 100-Year flood (1% Annual Exceedance Probability). The Scheme, which comprises conveyance improvement, Flood Defence embankments and walls, and pumping stations is expected to provide protection against the 100-Year flood (1% Annual Exceedance Probability) for about 285 properties from the River Bride. This layer shows the modelled extent of land that might be directly flooded by rainfall in a moderate rainfall event. These works would complement the existing flood scheme already completed in Mornington. Layer Information or associated variations in erosion rates. These hard defences would protect to the 1% AEP flood event with an average height of 0.8m and a total length of 0.6km. The data is added by councils or other authorised groups, allowing the information to be shared by government agencies and other stakeholders. The proposed measure consists of embankments and walls which would protect properties to both the 0.5% AEP coastal events and 1% fluvial events. They are also commonly referred to in terms of a return period (e.g. This data shows the modelled extent of land that might be flooded by rivers (fluvial flooding) during a theoretical or design flood event with an estimated probability of occurrence, rather than information for actual floods that have occurred in the past.

It is currently at the Outline Design and Exhibition stage, and is expected to go to construction in 2018. The Scheme comprises flood defence walls and embankments, channel conveyance improvements, a flood bypass channel, and watercourse diversions and provides protection against a 1% AEP (100 year) fluvial event from the Mulkear River and tributaries for 70 properties. The OPW is required to maintain drainage schemes under sections 37 and 38 of the Arterial Drainage Act, 1945. The Dodder CFRAM Study included an assessment of the Little Dargle Stream. The AFAs were the focus of the CFRAM Studies. Floodgates would also be required at a number of locations along the wall to maintain access to the port. 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. It is currently at the Detailed Design stage, and is expected to go to construction in 2018. The Embankments layer identifies the embankments that form part of Land Commission Embankments. The Irish Coastal Protection Strategy Study (ICPSS) flood hazard mapping is for strategic purposes, The vast majority of the Funding was provided by the Office of Public Works for this 20m scheme in three different counties. Phase 2 involves providing flood protection at the 700m section of sea walI north of the promenade to Sean Moore Park. This layer shows the modelled extent of land that might be flooded by the sea in a moderate flood event. defence works potentially protecting the coastal floodplain are not taken into account. The Scheme comprises flood defence walls and embankments along the Brosna River and provides protection against a 1% AEP (100 year) fluvial event from the Brosna River for 20 properties. Existing arterial drainage maintenance scheme will need to be maintained as part of this option. The Duleek Flood Relief scheme was initiated in 1995 and was constructed from 1997 to 1998.

To create a report zoom and click on a location of intrest - a symbol will The scheme comprises flood defence embankments and provides protection against a 1% AEP (100 year) fluvial event from the Owenagarney River for 16 properties. This represents the probability of an event of this, or greater, severity occurring in any given year. The northern phase was constructed between 2009 and 2010. The proposed measure would include the construction of an embankment measuring 415m long and 1.2m average height to store / attenuate flood water in larger events and an associated controlled outfall to prevent overland flooding of properties downstream (including the Woodlands Estate and the nursing home) when flow exceeds the existing culvert capacity. In the 0.5% coastal AEP design event the high tide in the Shannon estuary will exceed the water level inside the dock and overtop the existing gates. The Bandon River (Dunmanway) Drainage Scheme was initiated in 1990 following major flooding in 1986, and was constructed from 2000 to 2002. This will fit into the height of the existing river walls and maintain some visual connection. Two weirs would be removed on the Nuenna River (02WEIR02 at Chainage 1227 and 03WEIR01 and Chainage 1240). The Present Day maps were generated using methodologies based on historic flood data, without taking account of potential changes due to climate change. Flood event probabilities are referred to in terms of a percentage Annual Exceedance Probability, or AEP. 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). The purpose of the schemes was to improve land for agriculture, by lowering water levels during the growing season to reduce waterlogging on the land beside watercourses known as callows. a multiple flood point symbol is used. The embankment would protect to the 1% AEP flood event with an estimated average height of 0.9m and a total length of 53m. comhaontaonn t nach n-sidfidh t an Suomh Grasin agus/n an Larscili Tscach Abhann Nisinta chun crocha mdhleathacha, agus go n-urramidh t gach dl agus rialachn is infheidhme. The hard defences would protect to the 1% AEP fluvial flood event and to the 0.5% AEP coastal flood event, with an average height of 1.95m and a total length of 4.3km. though at present a flood defence is protecting them. A flood risk assessment was completed and a flood relief scheme proposed for the downstream extent of the watercourse close to its confluence with the Dodder. The Present Day Scenario is also referred to as the Current Scenario. The proposed measure consist of walls and embankments with a maximum height of 2.0m along the River Bandon.

In accordance with the Guidelines on the Planning System and Flood Risk Management (DECLG/OPW, 2009), planning authorities should seek to reduce the extent of hard surfacing and paving and require the use of sustainable drainage techniques to reduce the potential impact of development on flood risk downstream. The works were primarily to restore the old Drainage District scheme and comprised making good the embankments and some improvements, such as the deepening and widening of the restrictive stretch alongside the Bunky tributary. The Hard Defences would provide design SoP with an average height of 1m and a total length of 3km. potentially protecting the coastal floodplain are not taken into account. changes due to climate change. Rivers , lakes weirs and bridges were modified to enhance conveyance, embankments were built to control the movement of flood water and various other work was carried out under Part II of the Arterial Drainage Act, 1945. the maps should not be used to assess the erosion hazard and risk associated with individual properties The Present Day maps were This is also referred to as an Annual Exceedance Probability (AEP) of 0.1%.

A tidal flood forecasting and warning system to include high resolution forecasts for Westport Quay is to be developed. The flood alleviation works at Leighlinbridge were initiated in 2010 following flooding in 2009 which overwhelmed existing defences, and were constructed from 2011 to 2012. It was noted at the Public Consultation Day in Foynes during the Draft Flood Mapping stage that the sluice gate at this location is not currently maintained and there is silt build up, maintaining and removing the silt would help reduce flood risk. generated using methodologies based on historic flood data, without taking account of potential changes due to climate A third phase downstream of Raheny village is planned for construction thereafter again subject to funding and planning approval. The last schemes were completed in the 1990s. Layer Information It is important to note that the exact positioning of the wall would need to be determined during detailed design stage following consultation with all the relevant stakeholders, as there are a number of pipeline and other utility services within the working corridor of the proposed defence wall.

Layer Information Flows are then handled by a surface system of roadways, paths, drainage reserves and easements. Full details are available here. The proposed measure would consist of a combination of hard defences and storage methods. Mount Shannon Road - Structural flood defences are required in this area. The OPW will work with the Environment Protection Agency, Local Authorities and other agencies during the project-level assessments of physical works and more broadly at a catchment-level to identify any measures, such as natural water retention measures (such as restoration of wetlands and woodlands), that can have benefits for Water Framework Directive, flood risk management and biodiversity objectives. Live updates, traveller information and personalised alerts for NSW roads. A flood study is a technical project that identifies flood behaviour such as depth, velocity and extent across the floodplain. 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. process models to improve our knowledge and understanding of the behaviour and impact of tides, wave and sediment transport at the coast and of how these may change over time and potentially increase risk for coastal communities.
