This option involves rehabilitating (i.e. Midday, Monday 20 March 1978 the Manning River at Taree hit a flood peak level of 5.45m just 15cms below the record flood of 1929. Construction was undertaken within three local authority areas Meath, Fingal and Dublin City. Embankment and raise the road to protect the Pier 17 business centre. Construction of 69m of new flood defence walls; Construct 2,065m of flood defence walls and 350m of flood defence embankment; Upgrade existing culvert along N63 Galway Road at Ballinagard tributary; Construction of 368m of new flood defence walls, 263m of new embankments, and a 13m flood gate to defend properties. When the drainage system is surcharged rainwater overflows into these storage areas and is released by gravity when the storm subsides and water levels in the drainage network abate. The allowance for GIA varies around the coastline and This scheme was undertaken by the OPW and is maintained as part of current duties. Ba cheart comhairle ghairmiil n speisialaithe a ghlacadh roimh ghnomh ar bith a dhanamh n staonadh na dhanamh, ar bhonn na Mapa Tuile n bhar an tSumh Grasin. High resolution forecasts are available at Galway Bay and, as part of a coastal flood forecasting system for Galway Bay, could be used to provide warning to the residents of Roundstone. Construct 630m of new structural flood defence walls and 213m of flood defence embankments. The map is a vector dataset. in any given year. It was noted at the Public Consultation Day in Foynes during the Draft Flood Mapping stage that the sluice gate at this location is not currently maintained and there is silt build up, maintaining and removing the silt would help reduce flood risk. Installation of a simple flood-forecasting unit, including an addition of telemetry to an existing hydrometric gauge to send warning messages when water level reaches a specified trigger point. These Hard Defences would protect to the 1% AEP fluvial event with an average height of 2.1m and a total length of 2.6km. Layer Information is not accounted for and needs to be considered separately. 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. National Indicative Fluvial Mapping (NIFM) Terms and Conditions. Introduction of maintenance programme for the defences and other watercourses within the AFA. 200 to 1) of the event occurring in any given year. These hard defences would protect to the 0.5% AEP coastal event and 1% AEP fluvial flood event with an average height of 1.4m and a total length of 797m. This layer shows the modelled extent of land that might be directly flooded by rainfall in an extremely severe rainfall event. The proposed measure relies on ood 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 ood protection. The flood extent and depth maps are suitable for the assessment of flood risk at a strategic scale only, and should not be used to assess the flood hazard and risk associated with individual properties or point locations, or to replace a detailed flood risk assessment. The December 2015 flooding was in excess of the 1% AEP design standard and so the proposed flood relief works do not protect to this standard, however a number of methods are technically viable and should be considered if extra funding is available to protect to a higher design standard. mean sea level of 1.0m (to 2100) has been used in the HEFS. The Historic Groundwater Flood Map shows the observed peak flood extents caused by groundwater in Ireland. Such costs will give sufficient level of certainty in the flood damages to screen potentially viable flood risk management methods.

The proposed measure for Naas that may be implemented after detailed assessment, including data collection and an assessment of potential non-fluvial sources, and then subsequent project-level assessment and planning or Exhibition and confirmation might include physical works, such as a series of hard defences (flood embankments and walls), storage, formalisation of an existing flow path to create a flow diversion channel and improvement of channel conveyance. 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. To get more information, such as flood event reports or photos where available, regarding these events click on the flood point/boundary symbol which will bring up a Flood Summary pop-up in which the information The exact alignment of the culvert to be reviewed at detailed design stage. Construct 591m of new flood defence walls. probabilities may also be expressed as odds (e.g. The Wad River Flood Alleviation Scheme was initiated in 2009 following two major flood events in this catchment in August 2008 and July 2009. The proposed measure consist of the provision of a storage area on the Dalua River upstream of the town along with fluvial Flood Defences on the Dalua and Allow rivers comprising of walls and embankments along with storm water pump stations. Measures at this level are measures aimed at managing or reducing flood risk in a particular community. $301,900. Layer Information Upgrade three existing culverts on the Ballincurra (Creek). for projected future changes in climate such as sea level rise, increased storm frequency Layer Information Two pumping stations (either new or upgraded existing) will be required to manage surface water and fluvial flooding behind the river walls, one on each bank of the River Moy. change.

The New Wingham Wharf, Officially Opened 15th December 2010, Manning River, Wingham, NSW. The Scheme comprises flood defence walls and embankments along the Brosna River and provides protection against a 1% AEP (100 year) fluvial event from the Brosna River for 20 properties. The Camac Flood Protection Project was initiated as part of the CFRAM process following major fluvial flooding in 1986 and 2011. The Ennis South Flood Relief Scheme has received An Bord Pleanla approval and is expected to go to construction in 2018. The Benefited land layer identifies areas reclaimed by Land Commission Embankments. This means that areas may Flooding from other reaches of river may occur, but has not been mapped, and so areas that are not shown as being within a The Schem comprises flood defence walls a flood ramp and flood gates, will provide protection for an estimated 100 properties. Therefore, the maps should not be used to assess the erosion hazard and risk associated with 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).

Credit: Twitter The Douglas (Togher) Flood Relief Scheme was initiated in 2014 following major flooding in 2012. Uimh. Hydrometric monitoring is proposed in Ballingeary to improve confidence in the design flows, noting that is has been reported that recent floods exceeded the level and extent of the predicted 1% AEP. The works were primarily to restore the old Drainage District scheme and comprised making good the embankments and some improvements, such as the deepening and widening of the restrictive stretch alongside the Bunky tributary. If any provision of the Terms and Conditions shall be unlawful, void or for any reason unenforceable, that provision shall be deemed severable and shall not affect the validity and enforceability of the remaining provisions. It is intended that the works will provide protection to properties at risk of flooding in the 1% AEP and a reduction in flood depths to properties in area.

GSI Groundwater Flooding Data Viewer. The proposed measure consists of a series of sea walls, flood embankments and flood walls. The Scheme, will comprise of general river maintenance and the construction of sheet piled and concrete walls as well as embankments. 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. 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. This is also referred to as an Annual Exceedance Probability (AEP) of 0.5%.
