Please read the following statements and conditions of use of the enclosed survey data carefully. Construction of a new flood defence wall, embankment and floodgates. This system would provide the ability to inform managing authorities and the public of the potential for failure or overtopping of flood defence structures and to trigger emergency response plans. 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. As such, it may not show the true peak flood extents. The maps include an increase of 2000mm in sea levels above the current scenario estimations. The hard defences would protect to the 1% AEP fluvial flood event, with an average height of 1.5m and a total length of 0.76km. Clean and maintain the Caherweesheen, Cloghers, Ballydunlea and Ballyvelly watercourses. The development of a flood forecasting system for the Boyne River Basin will progress as part of the development of the National Flood Forecasting Service. The Scheme, which comprises mainly of flood defence walls and embankments, provides protection against a 200-Year flood (0.5% Annual Exceedance Probability) for an estimated 1,000 buildings in Dublin City from tidal flooding. in any given year.

Cars line up on the roadside near Taree service centre, waiting for The highway to reopen after being inundated by flood waters (SMH) In and around Sydney: At Cattai, Wisemans Ferry Road is closed across the Cattai Creek bridge. The Dollymount Cycletrack and Flood Alleviation Scheme commenced construction in March 2015. The potential effects of climate change have been separately modelled and reported on. The scheme, that comprises flood defence walls and embankments, demountable flood defence walls, flood relief culverts with trash and security screens, penstocks, conveyance improvement, and pumping stations, provides protection against a 100-year flood (1% Annual Exceedance Probability) for about 230 properties from the (Munster) Blackwater River. The coastal Hard Defences would provide design SoP for the 0.5% coastal event with an average height of 0.7m and a total length of 1km. A detailed geotechnical structural and stability assessment of the existing embankments was not undertaken as part of the CFRAM study, but should be undertaken to determine the condition and stability of tese embankments, and what remedial or maintenance works might be required. A flood relief scheme for Little Island was developed under the Lee CFRAM Study, and proposed for progression to implementation in the Lee CFRAM Study. The Scheme, which comprises improving channel capacity by removing an existing unused bridge together with construction of flood defence embankments & walls upstream of the R123 (Balgriffin Cottages/Moyne Rd.)

The Dodder Tidal Flood Alleviation Scheme was initiated in 2003 following a major tidal flooding event in February 2002. Past flood events are represented on the map in three different ways. Each community was divided into one or more map tiles depending on area, and maps were produced for each tile. Weather; Weather Search; Radar; Satellite; Lightning; Webcams; Archive Most The proposed measure consists of a series of flood embankments and walls with additional measures in place to protect properties in the Milltown area. The user of these maps shall be deemed to have agreed to, and unconditionally accepted all of these statements and conditions. The maps were prepared for the purpose of assessing the degree of flood and erosion hazard and risk to assist in the identification and development of measures for managing the flood and erosion risk. Insurance Ireland and the Office of Public Works (OPW) have a common interest and objective in ensuring that appropriate and relevant information on OPW completed flood defence schemes is provided to insurers to facilitate, to the greatest extent possible, the availability to the public of insurance against the risk of flooding. 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.

Arterial Drainage Schemes are schemes the OPW has a statutory duty to maintain. The proposed measure for Carysfort Maretimo HPW that may be implemented after project-level assessment and planning or Exhibition and confirmation might include physical works, such as a series of flood defence walls and five offline storage areas. The Fairfield & Cherry Orchard area of Enniscorthy is affected by fluvial flooding, however, no properties are at flood risk during a 1% AEP event. All such rights are reserved. The scheme comprises flood defence walls and pumping stations and provides protection against a 1% AEP (100 year) fluvial event from the River Fergus for 450 properties. It was not possible to determine accurately what underground flow structures exist at the outflow from the lake, and so a robust hydraulic model could not be developed for the area. The proposed measure for Kerrykeel AFA that may be implemented after project-level assessment and planning or exhibition and confirmation might include physical works. The Groundwater Flooding High Probability map shows the expected flood extent of groundwater flooding in limestone regions for annual exceedance probabilities (AEPs) of 10%, which correspond with a return period of every 10 years. This system would provide the ability to inform managing authorities and the public of the potential for failure or overtopping of flood defence structures and to trigger emergency response plans. residential properties and 9 no non-residential properties at risk in Milltown from the 1% AEP event. This means that areas may be shown to N comhairle iad na larscileanna agus nl siad beartaithe a bheith mar chomhairle. The slow response of the River Moy means it is possible to develop a fluvial flood forecasting and warning system for Ballina and Foxford using local level gauges. The potential flood defences would consist of a series of flood embankments (average height of 1.2 m and a total length of 265m) and flood walls (average height of 1.2m and a total length of 503m) on the Suir River and its tributary. The potential flood defences would consist of the following: The potential measure would protect at-risk properties against the 1% AEP Fluvial flood event by flood defences. The development of a flood relief scheme is currently underway for Enniscorthy (Slaney). 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. Flood maps show how likely it is for an area to flood. Maintain existing arterial drainage channels along the Gorragh River; Remove the existing weir and localised levelling of the River bed on the Clodiagh River upstream of the R422 Bridge; Increase channel capacity by dredging a section of the Clodiagh River. The Arterial Drainage Act, 1945 contains a number of provisions for the management of Drainage Districts in Part III and Part VIII of the act. The proposed measure consists of a series of flood embankments, walls and improvement of channel conveyance. Please read the following statements, guidance notes and conditions of use of the maps carefully. Floodgates would also be required at a number of locations along the wall to maintain access to the port. Layer Information The Freemount Flood Relief Scheme was initiated in 1998 following major flooding in 1997, and was constructed in 2001 by Cork County Council. The proposed further measure for Foynes that may be implemented after project-level assessment and planning or Exhibition and confirmation might include: The Foynes Tidal Flood Alleviation Scheme was initiated in 2014 following major flooding in January and February of that year. The proposed measure consists of a combination of flow diversion and improved channel conveyance methods, at risk properties would be protected by the construction of two flow diversion channels. 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. Outside of the Arterial Drainage and Drainage District Schemes, landowners who have watercourses on their lands have a responsibility for their maintenance. Move mouse over station for more data. Levels in Lough Allen and Lough Ree are managed to ensure minimum navigation levels in the river during dry periods and to reduce the impacts of floods as far as reasonably possible. 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. Image source, .

Embankments were also constructed along some of this reach. The culvert is approximately 425m long. Drainage schemes cover approximately 20% of the country, typically the flattest areas. The level of risk in Hazelhatch may be considered to be low, with 4 properties identifed within the 1%AEP extent. 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 High-End Future Scenario extents where generated taking in the potential effects of climate change using an increase in rainfall of 30%. Within Fingal the scheme was constructed in Mulhuddart and comprises flood defence walls, embankments and a pumping station. Promotion of Individual and Community Resilience. Flood event probabilities are referred to in terms of a percentage Annual Exceedance Probability, or AEP. This is also referred to as an Annual Exceedance Probability (AEP) of 0.1%.

Hydraulic modelling indicates that there is no impact on water levels upstream or downstream of Strand Road. The proposed measure for Ballybay that may be implemented after project level assessment and planning or Exhibition and confirmation might include physical works. The December 2015 flooding was in excess of the 1% AEP design standard and so the proposed flood relief works do not protect to this standard, however a number of methods are technically viable and should be considered if extra funding is available to protect to a higher design standard. The proposed further measure for Maynooth 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) and an overland flow route. in Phase 2 of the Irish Coastal Wave and Water Level Modelling Study (ICWWS 2018). over 2m width). 1) The Minor flood system is the underground pipe system. It is expected to provide protection against a 100-Year flood (1% Annual Exceedance Probability) for fluvial flooding and a 200-Year flood (0.5% Annual Exceedance Probability) against tidal flooding.
