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. In addition to this Scheme, further developer led flood relief measures were completed along the watercourse.This option involves rehabilitating (i.e. Significant flooding has occurred in Crossmolina in October 1989, December 2006 and November 2015, with the highest on record in December 2015. The Scheme, comprises flood defence walls and embankments along the Nanny River and Paramadden stream and a storm water pumping station, provides protection against a 100-Year fluvial flood (1% Annual Exceedance Probability) for 88 properties.A flood relief scheme for Ratoath was developed under the FEM-FRAMS, elements of which have been constructed. The hard defences would protect to the 1% AEP fluvial flood event, with an average height of 1.4m and a total length of 0.5km.

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, that comprises involves increasing the channel capacity by widening the Gaybrook Stream along a 200m length at Aspen, provides protection for 9 properties against fluvial flooding.The Kilcock Flood Risk Assessment and Management Study was initiated in February 2009 to address deficiencies highlighted by An Bord Pleanála with previous flood risk assessments in the area and was completed in August 2009. Full details on the methodology used for the preparation of the pluvial flood maps are available The proposed measure consists of removing a restrictive bridge structure.The proposed measure for Downings AFA that may be implemented after project-level assessment and planning or exhibition and confirmation might include physical works. The majority of this data in AFAs is Light Detection and Ranging (LiDAR) data,

These improved conveyance methods would provide protection from the 1% AEP fluvial event and involve removing approximately 338m3 of sediment from within the channel and upgrading the culvert to a 2.1m x 1m box culvert. 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. storage volume of 135,014m3). The datasets described below are shown and appear on the legend of the PDF flood extent and

The Improvement of Channel Conveyance consists of 71m of upgraded culvert.The proposed measure consists of using storage areas providing a combined volume of 66,310m 3 on the Ballywilly Brook along with a series of embankments and walls along the Donagh River. This category only includes cookies that ensures basic functionalities and security features of the website. The Dodder CFRAM Study included an assessment of the St Endas and Tara Hill areas. The improvement of channel conveyance consists of the removal of a weir on the Ballynerin watercourse.The proposed measure for Old Connaught and Wilford 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) in conjunction with, a culvert upgrade and channel dredging at the Dublin Road adjacent to St Brendan’s School, and a flow diversion channel on the Old Connaught River. At risk properties would be protected by a series of flood embankments and walls, along with improvement of channel conveyance close to the downstream end of the Carricklawn River. Proposed diversion channel 1 being 3.12km long, 3m wide and 1.5m deep and proposed diversion channel 2 being 2.6km long, 3.5m wide for the first 878m and 3m wide for the remainder and 1.5m deep throughout. 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.The proposed measure consist of walls and embankments with a maximum height of 2.0m along the River Bandon.

which to base the analysis.Design rainfall profiles have been derived as the main hydraulic model inputs so that the surface - the 100-year flood), Fluvial flood risk is also simulated applying a design fluvial hydrograph within the risks associated with flooding are potentially significant, and where further, more detailed 2007 event. comparison of modelled flood outlines with observed flow paths and properties affected.

, and also for other reaches between the AFAs and down to the sea that are referred to as 'Medium of a particular probability. Global Flood Map uses NASA satellite data to show the areas of the world under water and at risk for flooding if ocean levels rise. One location would consist of 67m of flood walls between 1m and 1.8m high and tanking of two existing building walls. probability. Our Ireland FloodMap™ allows you to see how a flood will develop, so you can better prepare. Please click on an area of the map to get more information 10m for the AFA flood maps, whereas in reality depths may vary within a given square.Flood levels, depths and velocities are derived from the hydrodynamic models for the various event The defences would be required along with improvement of channel conveyance on the Blackrock River and Dundalk Blackwater River, along with Storage on the Castletown River. scenarios include for changes as set out in Table 2. The proposed measure for Ballybay that may be implemented after project level assessment and planning or Exhibition and confirmation might include physical works.
