The scheme provides protection for 53 properties in Newport against flooding from the Mulkear 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. The Dodder CFRAM Study included an assessment of the Little Dargle Stream. year. 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).

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. Layer Information 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. Those areas have at least a one-in-four chance of flooding during a 30-year mortgage. Most No protection is required at Riverside as depths are not above threshold level of the properties.

The Scheme will provide protection for approximately 80 properties against for 1% Annual Exceedance Probability flood event from the Clare River and Turlough areas at Carnmore / Cashla and Lakeview and which comprises of the following: The proposed measure would include the placement of quay defence walls in order to protect against the 0.5% AEP design event with an average wall height of 1.2m, as required for public safety. This means that areas The allowance for GIA varies around the coastline and When combined these works provide protection against a 100-Year flood (1% Annual Exceedance Probability) for 18 properties. The proper application of the Guidelines on the Planning System and Flood Risk Management (DECLG/OPW, 2009) by the planning authorities is essential to avoid inappropriate development in flood prone areas, and hence avoid unnecessary increases in flood risk into the future. Construction of new flood defence embankments of 177m and 60m respectively, and a new flood defence wall of 33m along the right bank.

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). The Flood Maps have been developed from detailed engineering analysis and modelling. Layer Information The works comprise largely of constructing flood defence walls, installing non return valves and some short sections of demountable defence and provide protection to 188 properties against the 0.5% AEP (200 year) coastal event. The improvement of channel conveyance consists of the removal of a weir on the Ballynerin watercourse. It is currently at detailed design stage, and is expected to go to construction in 2018. The hard defences will provide an SoP of 0.5% AEP for coastal flood events and an SoP of 1% AEP for fluvial flood events. defence is protecting them. 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. Clean and maintain the Caherweesheen, Cloghers, Ballydunlea and Ballyvelly watercourses. is not accounted for and needs to be considered separately.

The Scheme that comprises conveyance improvement works, Flood Defence embankments and walls, and pumping stations is expected to provide protection against the 100-year flood (1% Annual Exceedance Probability) for about 392 properties from the Bandon River. The Scheme is expected to provide protection against the 100-year fluvial flood (1.0% Annual Exceedance Probability) from the River Lee, and against the 200-year tide (0.5% Annual Exceedance Probability) for about 2,100 properties. The proposed measure consists of a series of flood embankments and walls. High resolution forecasts are available at Galway Bay and could be used to provide warning to Sligo town. 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 vast majority of the Funding was provided by the Office of Public Works for this 20m scheme in three different counties. They are also commonly referred to in terms of a return period (e.g. No additional measures specific to the Kilkenny (Nore) AFA are proposed.

As such, it may not show the true peak flood extents. The proposed measure would consist of a combination of hard defences and storage methods. include allowances for projected future changes in climate and glacial isostatic adjustment (GIA). Mill Race Watercourse - Two sluice gates capable of retaining coastal flood water to a level of 5m AoD Malin are required on the Mill Race watercourse. This map was made using satellite images (Copernicus Programme Sentinel-1), field data, aerial photos, as well as flood records from the past. From 2012 to the present large local flood water retention depressions (called swales as they are normally dry) have been constructed in Ashtown (2), Finglas, Cabra (2). This combination would protect to the 1% AEP fluvial flood event and 0.5% AEP coastal flood events. It has also been assumed that the bridge is structurally sound and capable of withstanding the loading forces of a 1% AEP fluvial flood event. On the Knockanelo (or Sruffaunbrogue) the inlets to the flood relief culvert and downstream culverts will be improved with some further works to the existing box culverts at Marian Crescent.

Conveyance could be improved by dredging the existing channel, which conveys the entire flow from the downstream end of the Carricklawn River over 271m before reaching the downstream of the Coolcots River and the sea. The proposed measure consists of a series of walls and embankments. An increase in Layer Information These embankments were created by landowners to reclaim land from rivers or the sea, typically in the 19th century. In all cases, derived works should include a reference to floodinfo.ie, and to the disclaimer above. The existing arterial drainage maintenance scheme will need to be maintained as part of this option. At risk properties in the Ringphuca area would be protected by upgrading a culvert adjacent to the River Lane estate and widening the channel upstream.

Layer Information The Groundwater Flood Probability Maps shows the probabilistic flood extent of groundwater flooding in limestone regions. During flood events the Silver stream acts as a flow path for flood waters from the River Suck. It was not possible The Scheme is ongoing, and analyses pure drainage network improvements or diversions of flood waters to neighbouring networks which have spare capacity to reduce local flood risk as much as possible.

It is possible that mechanisms that were outside the scope of the CFRAM study, such as pluvial and/or groundwater flooding or interactions with the canal, are a factor. Layer Information Upgrade three existing culverts on the Ballincurra (Creek). These hard defences would protect to the 1% AEP fluvial flood event with an average height of 1.36m and a total length of 0.64 km. The flood walls are required to be an average height of 1.0m and a total length of 200m. The proposed measure consists of a series of flood embankments and flood walls. 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. The Groundwater Flooding Low Probability map shows the expected flood extent of groundwater flooding in limestone regions for annual exceedance probabilities (AEPs) of 0.1%, which correspond with a return period of every 1000 years. A 85m long flood embankment with a typical height of 1m above ground level. The hard defences would protect to the 1% AEP fluvial flood event, with an average height of 1.1m (reaching a maximum height of 1.5m) and a total length of 4km.
