The proposed measure consists of a series of flood embankments and walls. Drainage Districts were carried out by the Commissioners of Public Works under a number of drainage and navigation acts from 1842 to the 1930s to improve land for agriculture and to mitigate flooding. The measure also includes the removal of the existing pipe under Finnihy Bridge. In some cases embankments were created and the area behind was allowed to flood and flush out a number of times to reduce the salt content of the soil. The hard defences would protect to the 1% AEP fluvial flood event with an average and maximum height of 1.2m and 2.9m respectively and a total length of 3.0km of wall and a total length of 2.1km of embankment. Layer Information 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 Scheme, will comprise of general river maintenance and the construction of sheet piled and concrete walls as well as embankments.

The Sandymount Flood Protection Project was initiated in 2003 following major tidal flooding in 2002. The proposed measure consists of the installation of a sluice gate under the N25 to prevent the natural propagation of tidal water into low lying lands to the north of the N25 and is expected to provide protection against a 200-Year flood (0.5% Annual Exceedance Probability). to inform the assessment of flood risk to individual sites or properties, the detailed assessment of flood risk to existing coastal infrastructure, the detailed evaluation The hard defences would protect to the 1% AEP fluvial flood event, with an average height of 0.8m (reaching a maximum height of 1.3m) and a total length of 640m. Construction of new flood defence wall parallel to the Kilkee East watercourse. 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 proposed measure for Loughlinstown 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 dredging, a bridge and culvert upgrade on the Shanganagh River and two storage areas on the Deansgrange River. The Scheme, that comprises a new river diversion channel, associated road and field crossing culverts along with fluvial flood defence walls and embankments is expected to provide protection against a 100-Year flood (1% Annual Exceedance Probability) for approximately 110 properties against flooding from River Mall. Additionally, a structural survey of the existing wall would be required to ensure it is fit for purpose as a flood defence. A 85m long flood embankment with a typical height of 1m above ground level. When required during a fluvial event and at high tidal water levels the two Pumping Stations would extract any flood water that cannot be discharged to Carlingford Harbour as normal. These hard defences would protect to the 0.5% AEP coastal event with an average height of 1.13m and a total length of 2.4km. 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. The Brosna (Westmeath, Offaly and Laois) was the first scheme, which commenced in 1947. The MOU has a specific focus on agreeing the basis on which information can be provided to the insurance industry on areas benefitting from flood relief schemes completed by the OPW.

The assessment found that the cost of protecting those properties was over four times the value of the potential flood damage to those same properties. It is expected that the Scheme will be completed to the Smurfit Weirs on Beaver Road in 2018. It is currently under construction and it is expected to be completed in 2019. The purpose of the schemes was to improve land for agriculture, to ensure that the 3 year flood was retained in bank this was achieved by lowering water levels during the growing season to reduce waterlogging on the land beside watercourses known as callows. The Scheme, that comprises tidal flood defences walls and floodgates as well as utilising the existing sea wall and 30-50m wide promenade, is expected to provide protection against a 200-Year flood (0.5% Annual Exceedance Probability) for 400 properties against flooding from high tides including associated waves. This scheme was undertaken by the OPW and is maintained as part of current duties. These Floodgates would also be required at a number of locations along the wall to maintain access to the port. 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. During flood events the Silver stream acts as a flow path for flood waters from the River Suck. Development applications Sub-menu. Some dredging (deepening and widening) of the stream is required for a distance upstream of the culvert entrance. The Present Day These hard defences would protect to the 1% AEP fluvial flood event and 0.5% AEP coastal event with 197m of wall height between 0.6m and 1.2m, and 160m of wall height between 1.2 and 2m.

The following table sets out a range of flood event probabilities for which Construction of a new flood defence embankment, floodgate and pump. Each community was divided into one or more map tiles depending on area, and maps were produced for each tile. Therefore, no additional measures specific to Enniscorthy are proposed. The flood extents were made using remote sensing images (Copernicus Programme Sentinel-1), which covered any site in Ireland every 4-6 days. 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. Parts of Sydney are also expected to flood later on Saturday, as the Warragamba dam overflows. 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 Raheny (Santry River) Flood Protection Project was initiated following major fluvial flooding in 1986, 2008, 2009 and 2011. Present Day Scenario data was generated using methodologies based on historic flood data, without taking account of potential changes due to climate change. Flows are then handled by a surface system of roadways, paths, drainage reserves and easements. shown in areas that are now adequately defended by coastal protection structures that were introduced during or after the assessment period.

A Flood Forecasting system for the Lower Shannon will also apply as part of this measure. The map is a vector dataset. Drains and sluices or pumps were also provided to take away rainwater that fell behind the embankments. Emergency construction started immediately following the November 2002 event with the majority of the works completed between 2003 and 2009. This is to include a Chapter on Recovery to include how funding for emergencies, particularly recovery costs, may be handled in the future. The scheme provides protection for 53 properties in Newport against flooding from the Mulkear River. Survey points At risk properties would also be protected by installing a trash screen upstream of a bridge which is susceptible to blockage. The potential measure would protect at-risk properties against the 1% AEP Fluvial flood event by flood defences. Measures at this level are policies and other works aimed at, or related to, reducing flood risk throughout the River Basin (e.g., spatial planning, emergency response planning and maintenance of drainage schemes), including properties outside of the communities at potentially significant risk (the 'AFAs'). This represents the probability of an event of this, or greater, severity occurring in any given year. available regarding that flood event is summarised and further information can be accessed.

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. The Mid-Range Future Scenario extents where generated taking in in the potential effects of climate change using an increase in rainfall of 20% and sea level rise of 500mm (20 inches). Flood forecasting will also be required as part of this measure. The proposed measure consist of fluvial Flood Defences comprising of walls and embankments up to a maximum height of 2.5m. The proposed measure for Athlone includes: The proposed measure for Ballinasloe that may be implemented after project-level assessment and planning or Exhibition and confirmation might include; The Derrymullan Flood works were initiated in 2010 following major flooding in the 2009 flood event, and constructed from 2010 to 2011. Arterial Drainage Schemes were carried out under the Arterial Drainage Act, 1945 to improve land for agriculture and to mitigate flooding. Arterial Drainage Schemes are schemes the OPW has a statutory duty to maintain. The floods are shown as polygons. Layer Information Arterial Drainage Schemes were carried out under the Arterial Drainage Act, 1945 to improve land for agriculture and to mitigate flooding. The Co. Meath elements of the works were primarily centred around Dunboyne and Clonee with flood defence walls and embankments along the Tolka River and a diversion of the Clonee Stream under the M3 Motorway. 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. The hard defences will provide a SoP of 1% AEP for fluvial flood events with an average and maximum height of 1.6m and 2.0m respectively and a total length of 350m. Printable maps have been created for the Present Day, Mid-Range Future Scenario (MRFS) and High End Future Expand this section to see national measures under consideration at the selected location. The event is derived from available flood information documentation including High Probability flood events have approximately a 1-in-a-10 chance of occurring or being exceeded in any given year. The floods are shown as polygons. One location would consist of 67m of flood walls between 1m and 1.8m high and tanking of two existing building walls. A series of sewers, non-return valves and a pumping station will be required to ensure that pluvial flooding is also reduced. The potential measure would protect at-risk properties against the 1% AEP Fluvial flood event by a combination of flood defences and Improved Channel Conveyance. This is also referred to as an Annual Exceedance Probability (AEP) of 0.5%. This represents the probability of an event of this, or greater, severity occurring in any given year. The Benefited land layer identifies land that was drained as part of the scheme. The Scheme, that comprises conveyance improvement, culvert removal and replacement, Flood Defence walls and a trash screen, is expected to provide protection against the 100-Year flood (1% Annual Exceedance Probability) for about 130 properties from the Ballybrack Stream in Douglas, as well as about 100 properties from the Tramore River in Togher. Discontinuing the existing regime of removing silt and debris from the outfall at Blackrock. may be shown to flood, even though at present a flood defence is protecting them. Data has been produced for catchments greater than 5km2 in areas for which flood maps were not produced under the National CFRAM Programme and should be The proposed measure consists of a series of flood embankments with revetment protection, walls, demountable barriers along the quays and a flood gate located on Shore Road. It is currently at planning / detail design stage, and is expected to go to construction in 2018. with regard to the accuracy of predictive flood models; however, the detailed models used have been developed using the best The total Scheme, which comprises of large drainage culverts, a large retention pond and flood flow control devices, will provide protection against an estimated current 100-Year fluvial flood (1% Annual Exceedance Probability) for approximately 206 buildings, as well as reducing flood risk to the Dublin to Belfast railway line, Howth Road, Malahide Road, Collins Avenue East and many local roadways in the Wad River Catchment.
