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 1m and a total length of 2.4km. The user understands that the Office of Public Works and the Government of Ireland does not guarantee the accuracy of any of the survey data presented and it is the user's responsibility to independently verify and quality control any of the data used and ensure that it is fit for their intended use. The Commissioners of Public Works in Ireland (the "Commissioners") have developed the Flood Maps for the Republic of Ireland ("Flood Maps") on www.floodinfo.ie (the "Website") as part of the Catchment Flood Risk Assessment and Management (CFRAM) Programme together with Dublin City Council, other Local Authorities and Ordnance Survey Ireland. The purpose of the Pilot Coastal Monitoring Survey Programme is to obtain up to date coastal survey data to inform and facilitate enhanced management of the associated coastal risks; quantify and identify 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. This interim scheme has been complemented by a more comprehensive scheme, which has been substantially completed, to provide a higher standard of protection and protect more properties in the town. The proposed measure relies on flood 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 flood protection. Upstream lock gates on the Plassey Canal - The existing canal lock gates need to be replaced as part of this measure. The Dodder Tidal Flood Alleviation Scheme was initiated in 2003 following a major tidal flooding event in February 2002. Some of these areas which had never been flooded before, in living memory, flooded again in October 2011 each time to a previously estimated one in 100 year local flood level. Flood defences along the property line and localised land and road raising in Salthill will manage wave overtopping risks. The proposed measure consists of a series of flood embankments and walls.

An earth embankment with an average height of 1m across the floodplain to prevent the flow route from the Milltown House Stream to provide complete protection to properties for the 1% AEP event. These hard defences would protect to the 1% AEP fluvial event with an average height of 1.85m and a total length of 797m. 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) 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. Emergency construction started immediately following the November 2002 event with the majority of the works completed between 2003 and 2009. Layer Information The maps include an increase of 2000mm in sea levels above the current scenario estimations. Dublin City Council (DCC) is currently preparing a request for funding to the Office of Public Works (OPW) for works on Phase 1B of the Wad River Flood alleviation scheme which will comprise works under the Howth Road and under Clontarf Promenade. Construction was undertaken within three local authority areas Meath, Fingal and Dublin City. Printable maps have been produced for the 300 communities (AFAs) at potentially significant flood risk from one or more sources of flooding. 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. Further information is available on the GSIGroundwater Flooding Data Viewer. The allowance for GIA varies around the coastline and At risk properties would be protected by a series of flood embankments, walls and two pumping stations. The scheme provides protection against a 100-Year flood (1% Annual Exceedance Probability) from the Gort/Cannahowna River for 21 properties. The Act was amended on a number of occasions, e.g. Tidal flood Defences along the quays and to the rear of properties comprising of sea walls, removable barriers / gates are included at certain locations to maintain existing access points along with storm water pump stations. Layer Information The Dunfanaghy pier would require approximately 850m2 of raising by an average of 900mm. The Hard Defences would provide design SoP with an average height of 1m and a total length of 3km. for projected future changes in climate such as sea level rise, increased storm frequency The North City Drainage Network Upgrades was initiated in 2010 following major flooding in August 2008 and July 2009 with construction subsequently commencing in 2012. Manning River at sunset. These Flood Defences are expected to provide protection against the 0.5% AEP tidal flood event. Taree Manning River Flooding on 4th March 2022 Show more Taree Floods Sat 20th March 2021 Coverage Armedia Productions 25K views 1 year ago Taree , is Town on Mid North Coast , New South. The Act was amended on a number of occasions, e.g. A flood study is a technical project that identifies flood behaviour such as depth, velocity and extent across the floodplain. Drainage schemes cover approximately 20% of the country, typically the flattest areas. M dhiltaonn t an comhaont dlthiil seo a dhanamh, n fhadfaidh t dul ar aghaidh chun an Suomh Grasin seo a sid n rochtain a fhil ar aon bhar ar an Suomh Grasin. The areas around Port Macquarie and Taree, where the Hastings and Manning Rivers respectively run through, have been the focus of much of the devastation on the Mid North Coast over the past few days as a result of flooding. The potential improvement in channel conveyance would consist of a bridge replacement of the existing bridge on Main Street and channel maintenance between the Ardfinnan Road and the Suir. Condition of Use Improve the capacity of the River Ballynabrennagh and provide embankments on the left bank. Coastal flooding may also be referred to as tidal flooding in the maps and reports. The vast majority of the Funding was provided by the Office of Public Works for this 20m scheme in three different counties. The proposed measure for Rathmullan AFA that may be implemented after project-level assessment and planning or exhibition and confirmation might include physical works. When combined these works provide protection against a 100-Year flood (1% Annual Exceedance Probability) for 332 properties. The Flood Maps have been developed from detailed engineering analysis and modelling. Construct wall to protect properties adjacent to the canal at Blennerville. Construction of new flood defence walls of total length 850m along the right bank of the Kilkee Lower (River) watercourse and along the left and right bank of the Kilkee Upper (River) watercourse. The potential effects of climate change have been separately modelled and reported on. The Lower Morrell (Straffan) Flood Relief Scheme was initiated in 2010 following major flooding in 2009. Additionally, a structural survey of the existing wall would be required to ensure it is fit for purpose as a flood defence. No additional measures specific to Tullow AFA are proposed. Any works that may be proposed following the necessary ecological and engineering studies will be subject to the relevant consent processes including environmental. The Embankments layer identifies the embankments that form part of Drainage Districts. An area of land (catchment) draining to a particular estuary or reach of coastline. As such, it should be used with caution. The proposed measure for Dromod that may be implemented after project-level assessment and planning or Exhibition and confirmation might include; The proposed measure for Leitrim village that may be implemented after project-level assessment and planning or Exhibition and confirmation might include; The proposed measure for Athleague that may be implemented after project-level assessment and planning or Exhibition and confirmation might include: The proposed measure for Bunratty that may be implemented after project-level assessment and planning or Exhibition and confirmation, might include: The proposed measure for Kilkee that may be implemented after project-level assessment and planning or Exhibition and confirmation, might include: The proposed measure for Kilrush that may be implemented after project-level assessment and planning or Exhibition and confirmation, might include; The proposed measure for Shannon town that may be implemented after project-level assessment and planning or Exhibition and confirmation, might include: The Sixmilebridge Scheme was constructed in 1996/1997. This data shows the extent of land that might be flooded by the sea (coastal flooding) and the associated flood depths 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. 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). The bush fire prone land online mapping tool ("Tool") has been created using NSW Local Council's bush fire prone maps and is designed to identify if your property is designated as bush fire prone. The hard defences option would also require a number of culverts through flood defences to be constructed including non-return valves. The maps were derived from synthetic aperture radar (SAR) data acquired by the Copernicus Sentinel-1 satellites, operated by the European Space Agency (ESA). Flooding from other sources may occur and areas that are not shown as being within a flood extent may therefore be at risk of flooding from other sources. or associated variations in erosion rates. Raised road level over a length of 20m along the north of Portumna Harbour. Low Probability flood events have an indicative 1-in-a-1000 chance of occurring or being exceeded in any given year. These works provide protection against a 100-Year flood (1% Annual Exceedance Probability) for an estimated 1,346 buildings in Dublin City against flood damage from mainly river flooding although a small number of these were at tidal flooding risk as well. The scheme comprises flood defence embankments and provides protection against a 1% AEP (100 year) fluvial event from the Owenagarney River for 16 properties. The New Wingham Wharf, Officially Opened 15th December 2010, Manning River, Wingham, NSW. 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. Replace culvert on Benedin Stream with hydraulic control to limit flows downstream during flood events. The scheme also includes a new diversion channel from Forenaghts to the Morrell River. Those areas have at least a one-in-four chance of flooding during a 30-year mortgage. in open coastal areas) would have to be designed to accommodate wave overtopping during the detailed design phase. Medium Probability flood events have approximately a 1-in-a-100 chance of occurring or being exceeded in any given year. A Government decision was taken on 5 January 2016 to establish a National Flood Forecasting and Warning Service. 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. It is currently at Design stage and is expected to go to planning in mid-2018. 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.

Improving the channel conveyance of a tributary at the AFAs northern boundary would consist of removing three weirs, dredging a length of 18m of the river and underpinning a bridge. The proposed measure consist of Fluvial Flood Defences comprising of walls and embankments on the Finnihy and Kealnagower rivers and Tidal Flood Defences comprising of walls, embankments and removable barriers. 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.
