Currently there are three agencies with a statutory interest in the water levels along the River Shannon; namely the OPW, ESB and Waterways Ireland (WI). This layer shows the modelled extent of land that might be directly flooded by rainfall in a moderate rainfall event. The scheme, that comprised improved channel conveyance, raised wall, culvert bypasses and screen upgrades, provides protection against a 1:50 to 1:100 year flood event (1-2% Annual Exceedance Probability) for 40 plus properties, against flooding from the Carysfort Maretimo Stream. to transpose EU Regulations and Directives such as the EIA, SEA, and Habitats Directives and the Aarhus Convention. Therefore, this measure should be an improved sluice or flapped outfall arrangement with an accompanying active inspection and maintenance regime. One location would consist of 67m of flood walls between 1m and 1.8m high and tanking of two existing building walls. The Benefited land layer identifies areas reclaimed by Land Commission Embankments.

It is currently at the Outline Design and Planning stage, and is expected to go to construction in 2018. or encourage members of the public to visit flood event locations for the purpose of recording flood event data. Part IV of the Arterial Drainage Act, 1945 created a provision for embankments to be absorbed into drainage schemes. Layer Information a multiple flood point symbol is used. 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. A flood study is a technical project that identifies flood behaviour such as depth, velocity and extent across the floodplain. The Scheme, which comprises construction of flood embankments is expected to provide protection against an estimated 100-Year fluvial flood (1% Annual Exceedance Probability) for 2 properties. from other sources (wave overtopping, fluvial, sewers, etc.) Waterways Ireland owns, maintains and operates further infrastructure, such as weirs and some navigation canals, related to navigation on the River Shannon. 100 to 1) of the event occurring in any given year.

The proposed measure consist of Flood Defence walls and embankments. It was not possible to eliminate It provides protection against a 50-Year flood (2% Annual Exceedance Probability) for 110 properties against flooding from the River Suir. The proposed measure for Killybegs AFA that may be implemented after project-level assessment and planning or exhibition and confirmation might include physical works. This is also referred to as an Annual Exceedance Probability (AEP) of 10%. The map is a vector dataset. 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 average height of these embankments is 0.6m and provides protection up to the 1% AEP fluvial event and 0.5% AEP tidal event. A 85m long flood embankment with a typical height of 1m above ground level. The work undertaken for the Dublin FloodResilienCity Project forms the basis of a Pluvial Flood Risk Management Strategy for Dublin. The developer led study proposed a flood risk management option, which would protect existing properties and proposed development areas against flooding from the River Rye Water. The proposed measure would protect at risk properties by a series of hard defences consisting of flood embankments and walls. Measures at this level are aimed at managing or reducing flood risk in more than one community. The sections at Merrion Gates and opposite Marine Drive have been constructed. Maintain existing flood forecasting and public awareness campaign operated by the ESB. Flood defences were previously built to protect properties in the community of Tower / Blarney. A 125m length of road would also have to be raised. Layer Information The Mid-Range Future Scenario (MRFS) maps represent a projected future scenario for the end of century (circa 2100) and include allowances for projected future changes in sea levels and glacial isostatic adjustment (GIA). The Scheme, that comprises mainly of tidal Flood Defences walls and upstream storage in a retention basin upstream of the town, in addition to pump stations, localised defences and repair works to the existing channel banks, to provide protection against a 100-Year flood (1.0% Annual Exceedance Probability) for fluvial and a 200-Year flood (0.5% Annual Exceedance Probability) for tidal for 296 properties against flooding from either fluvial flooding, tidal flooding or both. As such, there is further scope for the community views to influence the measure that is progressed to implementation. The OPW is required to maintain drainage schemes under sections 37 and 38 of the Arterial Drainage Act, 1945. This data shows the extent of land that might be flooded by the sea (coastal 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. The Scheme comprises of flood defence walls, embankments, localised floating barriers and pumping stations for storm water that would otherwise accumulate behind the defences. These probabilities may also be expressed as odds (e.g. 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 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. In addition, the flood This is also referred to as an Annual Exceedance Probability (AEP) of 0.5% or 0.1%. Improve inlet arrangement at the diversion channel diverting flow from the River Big to the River Ratass. This dataset shows the shoreline combined wave climate and water level conditions for the Coastal Areas Potentially Vulnerable to Wave Overtopping (CAPOs) that were included The scheme comprises flood defence embankments and flow diversion culverts and is expected to provide protection against a 1% AEP (100 year) fluvial event.

Uimh 279 2005 arna leas ag I.R. 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. 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. The Raheny (Santry River) Flood Protection Project was initiated following major fluvial flooding in 1986, 2008, 2009 and 2011. This layer shows the modelled extent of land that might be flooded by the sea in a very extreme flood event. Further information can be found in the Flood Map Review Guidance Note. This system would include a "level trigger flood warning" which would require the installation of a new telemetered level gauge at Gort Bridge. include allowances for projected future changes in climate and glacial isostatic adjustment (GIA). defences fail or not be maintained in the future. 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 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.

Layer Information line is shown that are at risk from erosion, should present defences fail or not be maintained in the future. The Winter 2015/2016 Surface Water Flooding map shows fluvial (rivers) and pluvial (rain) floods, excluding urban areas, during the winter 2015/2016 flood event, and was developed as a by-product of the historic groundwater flood map. The Act was amended on a number of occasions, e.g. Manning River at Taree: Cancellation Flood Safety Advice: In life threatening emergencies, call 000 (triple zero) immediately. The Present Day Scenario is referred to as the Current Scenario in the maps and reports. Medium Probability flood events have approximately a 1-in-a-100 chance of occurring or being exceeded in any given year. Flows are then handled by a surface system of roadways, paths, drainage reserves and easements. The Present Day Scenario is also referred to as the Current Scenario. This layer shows the modelled extent of land that might be flooded by rivers in a severe flood event. 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. It is assumed that existing flood defences can be extended, the required extension height and associated base width was determined. 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.

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. A third City wide event in October 2011 again caused significant flooding in this catchment. Separate maps were typically produced for each source of flooding relevant to the community. This dataset shows areas that have been or are planned to be surveyed as part of the Pilot Coastal Monitoring Survey Programme - Aerial Photography Surveys. When combined these works provide protection against a 100-Year flood (1% Annual Exceedance Probability) for 332 properties. The Duleek Flood Relief scheme was initiated in 1995 and was constructed from 1997 to 1998. This map was made using satellite images (Copernicus Programme Sentinel-1), field data, aerial photos, as well as flood records from the past. 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.
