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. Further information is available on the GSIGroundwater Flooding Data Viewer. The outputs of this study are considered suitable to inform the assessment of flood risk at a community level. probabilities may also be expressed as odds (e.g. Within Dublin City the scheme, comprises flood defence walls, embankments, channel conveyance improvements, a new raised bridge in Griffith Park and a pumping station adjacent to Drumcondra Bridge and Botanic Avenue for storm water that would otherwise accumulate behind the new defences. The proposed measure consists of building hard defences and improvement of channel conveyance. The location and volume of storage determine the locations and heights of hard defences required downstream, these issues will be considered at project-level assessment stage. Evacuation warnings have.

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 new lock gates will be higher than the existing gates and be capable of retaining flood water on the upstream side to a level of 6.5m AoD Malin. The Scheme, which comprises 2.1km of tidal flood defences walls and engineered embankments, glass flood panels, demountable barriers, drainage and storm water pumping. 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. Raise 500m section of the Old Cratloe Road. Click on a Location of Intrest to Create Report. to transpose EU Regulations and Directives such as the EIA, SEA, and Habitats Directives and the Aarhus Convention. When Phase 1B is complete DCC will make an application to OPW for funding to carry out a second phase of the Scheme along Collins Avenue East, Malahide Road and Collins Park. The low benefit-cost ratio is due to the relatively low risk to properties during the 1% AEP fluvial flood event in Trim, resulting in a small benefit value. not have been included in their preparation. Scenario (HEFS) flood extents and the Present Day flood depths. The hard defences would protect to the 1% AEP fluvial flood event, with an average and maximum height of 1.2m and 2.1m respectively and a total length of 461m. The hard defences have an average height of 1.6m (reaching a maximum height of 3.4m). However, Trim could benefit from the implementation of the Boyne Flood Forecasting and Warning System, The Ashbourne Flood Relief Scheme was initiated in 2015 following major flooding in November 2014. The Present Day scenario is referred to as the Current Scenario in the Maps and Plans.

The proposed measure consist of flood walls and embankments to protect vulnerable properties in Inchigeelagh. In April/May 2000, flood alleviation works were undertaken by the local community in Mullinahone, funded by the OPW through South Tipperary County Council. The potential improvement in channel conveyance would consist of a bridge replacement with a culvert (1.6m x 6m wide) on the Cromoge River and pipe replacement with culvert (2m x 8m x 15m long) on the Coolataggle tributary. Culvert; Upgrade the existing Kilclooney Road Bridge on the River Deerpark; Regarding of the riverbed upstream and downstream of Kilclooney Road Bridge to maximize efficiency of the upgraded structure; Public Awareness, Flood Forecasting will also be required as part of this measure; The West and East Atlas channels need to be maintained to ensure their full capacity can be utilised in a flood event. Low Probability flood events have an indicative 1-in-a-1000 chance of occurring or being exceeded in any given year. It is currently at planning / detail design stage, and is expected to go to construction in 2018. Coastal flooding may also be referred to as Tidal flooding in the Maps and Plans. Such was the case in the Manning catchment in 1978. The scheme also provided trash screens and flap valves on channels, where appropriate, and repairing a damaged wall at Parsons Lane. Hydraulic modelling indicates that there is no impact on water levels upstream or downstream of Strand Road. An increase in mean sea level Layer Information The ESB owns, maintains and operates a range of infrastructure along the River Shannon related to power generation at Ardnacrusha hydro-power station. Data has been produced for the 'Areas of Further Assessment' (AFAs), as required by the EU 'Floods' Directive [2007/60/EC] and designated under the Preliminary Flood Risk Assessment , and also for other reaches between the AFAs and down to the sea that are referred to as 'Medium Priority Watercourses' (MPWs). Arterial Drainage Schemes were carried out under the Arterial Drainage Act, 1945 to improve land for agriculture and to mitigate flooding. Bogland and other lands are identified separately. The Commissioners of Public Works in Ireland (the "Commissioners") have developed the National Indicative Flood Mapping Data for the Republic of Ireland as part of the National Indicative Flood Mapping Project (2019-2020). 2 Baths. These hard defences would be set back from the river channel where possible and would protect to the 1% AEP fluvial flood event with an estimated average height of 1.2m and length of 2.9km. The survey commenced in mid-September 2003 and was completed in 11 days. Recipe (for disaster): -5.3 million poops (Sydney pop'n, per day) -53 million squares of toilet paper -26.5 million litres of toilet water -about 4 million assorted unmentionables that also get flushed down the toilet. In front of the Cathedral on the N59, 210m of river bank will be raised to fit into the existing landscape. The ongoing collection and, where appropriate, publication of flood-related data will help to continually improve preparation for, and response to, flooding. Layer Information This is also referred to as an Annual Exceedance Probability (AEP) of 0.5%. The proposed measure consist of Fluvial Flood Defences comprising of walls and embankments. It is currently at Confirmation stage under the Arterial Drainage Acts, and is expected to go to construction in 2018. The Scheme, which comprises largely of a control structure and a bypass culvert built almost entirely under the streets of the village, provides protection to 10 properties against the 1% AEP (100 year) fluvial event. Present Day Scenario data was generated using methodologies based on historic flood data, without taking account of potential changes due to climate change. The potential measure would protect at-risk properties against the 1% AEP Fluvial flood event by flood defences. You accept that the Commissioners reserve the right to change the content and/or presentation of the National Indicative Fluvial Mapping or any other content of the Website at their sole discretion at any time, and to change the Terms and Conditions. Mount Shannon Road - Structural flood defences are required in this area. The proposed measure for Naas that may be implemented after detailed assessment, including data collection and an assessment of potential non-fluvial sources, and then subsequent project-level assessment and planning or Exhibition and confirmation might include physical works, such as a series of hard defences (flood embankments and walls), storage, formalisation of an existing flow path to create a flow diversion channel and improvement of channel conveyance. 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. Use of these maps is conditional upon the following: Disclaimer Emergency construction started immediately following this tidal flooding event and continued with new flood walls adjacent to Stella Gardens in 2003 and 2004.

Flooding from other reaches of river may occur, but has not been mapped, and so areas that are not shown as being within a flood extent may therefore be at risk of flooding from unmodelled rivers (as well as from other sources). Flood event probabilities are referred to in terms of a percentage Annual Exceedance Probability, or AEP. This layer shows the modelled extent of land that might be flooded by the sea in a very extreme flood event. 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. and erosion related data presented on these maps are copyright of the Office of Public Works.

This would reduce flow along the Ballyhale watercourse therefore significantly reducing the extent of hard defences required. The Act was amended on a number of occasions, e.g. Drainage schemes cover approximately 20% of the country, typically the flattest areas. However, there is a history of extensive flooding, which could not be replicated in the CFRAM Study Mapping. At the same time as progressing potentially viable flood relief works in the Cois Aibhainn flood cell, a more detailed assessment of the costs to be progressed to determine if an economically viable measure, for the whole of the Westport AFA, may in fact exist that could justify the progression to full project-level assessment.

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. Part IV of the Arterial Drainage Act, 1945 created a provision for embankments to be absorbed into drainage schemes. The Mid-North Coast town was inundated with water, with many forced to evacuate. 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. extent mapping only takes into account coastal flooding from a combination of tide levels and storm surges; any These probabilities may also be expressed as the chance or odds (e.g. defence is protecting them. The hard defences required to protect to the 1% AEP fluvial flood event and a 0.5% AEP coastal flood event, have an estimated average height of 1.4m and a total length of 1.3km. This represents the probability of an event of this, or greater, severity occurring in any given year. 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. Construction of an embankment, 325m long with an average height 1-1.5m above ground level. The Hard Defences would provide design SoP with an average height of 1m and a total length of 3km. Therefore, floods without extent information are represented with a point symbol at the approximate location of the flood. Full details are available here. The scheme comprises flood defence embankments and provides protection against a 1% AEP (100 year) fluvial event from the Owenagarney River for 16 properties. Measures at this level are measures aimed at managing or reducing flood risk in a particular community. Increase the height of 0.9km of existing embankments and raise approximately 30m of road in order to eliminate flood risk to the properties within the 1% AEP 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). year.

Some residents of the NSW town of Taree have started returning to clean what's left of their properties damaged by flooding. These datasets show the detailed shoreline combined wave climate and water level conditions for the Coastal Areas Potentially Vulnerable to Wave Overtopping (CAPOs) Significant flooding has occurred in Crossmolina in October 1989, December 2006 and November 2015, with the highest on record in December 2015. The scheme provides protection against a 100-Year flood (1% Annual Exceedance Probability) from the Gort/Cannahowna River for 21 properties. 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. From drone video footage, and images captured by the public, it can be seen that there were significant floods in north Port Macquarie, at Settlement Point (0.5 - 1.5m), at Shoreline Drive, and at The Anchorage. Outside of the Arterial Drainage and Drainage District Schemes, landowners who have watercourses on their lands have a responsibility for their maintenance. 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. Installation of a simple flood forecasting unit, which includes the addition of telemetry to an existing hydrometric gauge to send warning messages when water level reaches a specified trigger point. The Sandymount Flood Protection Project was initiated in 2003 following major tidal flooding in 2002. Licence Layer Information 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. Check for bush fire warnings and information. 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. ), Data is licensed under theCreative Commons By Attribution (CC-BY)version 4.0 license - seehere for a summary, Galway City Coastal Wave and Water Level Modelling Study (CWWS) 2020. Under the terms of the MOU, Insurance Ireland requires the OPW to provide it with data on OPW completed flood defence schemes which shows the design, extent and nature of the protections offered by these works. To request data for areas where surveys have been completed please email flood_data@opw.ie. The quay walls would extend from the dock, continuing along Long Walk and Spanish Arch. 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 Fermoy (North) Flood Relief Scheme, that comprises flood defence walls and embankments, demountable flood defence walls, and pumping stations, provides protection against a 100-year flood (1% Annual Exceedance Probability) for about 77 properties from the (Munster) Blackwater River.
