#COASTAL NOTES - It's an alarming figure by any means - new research shows that the level of the Irish Sea will rise by almost half a metre by the end of the century, leading to much more severe flooding along the east coast and elsewhere.

The results of research published by the Ryan Institute at NUI Galway, as reported by The Irish Times, show that sea level rises of up to 47cm are not out of the question.

They also indicate that sea surface temperatures will increase by nearly 2 degrees, which would have serious implications for marine wildlife and the fishing industry.

Dr Mike Hartnett of the Tyan Institute said the new research - from 3D model-based projections of the seas around Ireland - is the most comprehensive study of its kind, and confirms previous "tentative" studies in the area.

The news comes after national weather forecaster Met Éireann announced an incredible 0.75 degree rise in average temperature in Ireland - and a 5% increase in rainfall - over the past two decades alone.

And with recent flooding in Cork and Belfast causing millions of euro worth of damage, the real implications of such figures is coming closer to home.

#FLOODING - The clean-up has begun across Cork city and county after heavy flooding over the past two days resulted in millions of euro worth of damage, as The Irish Times reports.

Debris blocking a rubbish screen on a new culvert on the Douglas river has been blamed for the more than four feet of flood water that swamped the suburb of Douglas south of Cork city.

Elsewhere in the city, six people were evacuated from homes in the Meadow Brook Estate in Glanmire after the Glashaboy river burst its banks.

RTÉ News - which has a photo gallery of affected areas in and around Cork - reports that electricity is being restored to most customers after widespread power outages.

Met Éireann's Eoin Sherlock said that nearly 50mm of rain fell in a single six-hour period on Wednesday night - more than two-thirds of the monthly average rainfall for June.

Meanwhile, in Belfast politicians face public anger over flash flooding overwhelmed the city and left major routes impassable and sparked concerns over rising sewage water.

According to the Irish Independent, Northern Ireland emergency services reported more than 700 call-outs linked to the flooding in greater Belfast alone.

Minister for Regional Development Danny Kennedy, who is responsible for the North's roads and water system, said that "no infrastructure would have been able to cope with the level of rainfall that we have seen.

"It simply isn't designed to cope with those volumes of rain."

#WEATHER - Met Éireann is warning that more gale force winds will affect many parts of Ireland and the Irish Sea today (28 December).

According to the forecaster, stormy conditions over Connacht, Ulster and parts of north Leinster will see gale force westerly winds with gusts of between 100 and 130 km/h.

The worst winds are expected in exposed coastal and hilly areas of Ulster and Connacht. There is also an increased risk of flooding as a result of high astronomical tides combined with very high seas.

#INLAND WATERWAYS - Sluice gates have been opened at locks and dams along the River Shannon due to flooding concerns, The Irish Times reports.
The ESB confirmed that water levels in the upper Shannon had been rising significantly since September, and were just below those recorded prior to the flooding in Carrick-on-Shannon two years ago.
However the flooding threat has abated this week, with levels in Lough Allen dropping by around 300cm, although the situation is still subject to amounts of rainfall in the coming days as the Shannon drains slowly.
Levels in Lough Ree have also stabilised after rising throughout October.
The ESB continues to discharge from the Ardnacrusha power plant, while Waterways Ireland has commenced dredging at Meelick in Co Galway.

The body of an off-duty garda who was swept away by floodwater in Co Wicklow during Monday's torrential rain has been recovered.
The Irish Times reports that 25-year-old Garda Ciaran Jones was pulled into the River Liffey at the Ballysmuttan Bridge around 7pm on Monday while warning motorists not to cross the bridge.
A search and rescue operation was immediately launched involving the Irish Coast Guard, the Garda helicopter and mountain and river rescue teams, according to the Irish Examiner.
His body was eventually found at 9am yesterday morning some 4km downstream.
Supt Eamon Keogh of Blessington Garda Station noted that Garda Jones had been crossing the bridge to warn an oncoming car when he was swept into the swollen river by a sudden surge of water.
Taoiseach Enda Kenny led tributes to the young garda as well as a woman who died at her home in Dublin during the flooding that caused chaos across the east of Ireland on Monday evening, with several inland waterways bursting their banks.

A combination of high tides, high winds and low pressure increase the possibility of coastal flooding, particularly at high tide around midnight on Sunday 7 November and midday on Monday 8 November.

A deep low pressure centre is expected to move down across Ireland tonight, clearing away slowly during Monday. This weather system has the potential to bring some severe weather to Ireland. Rainfall totals are likely to reach 25mm - 30mm in places during Sunday and Monday. While not excessive, this rain may lead to some localised flooding on roads. The strongest winds associated with this weather system are likely to be well to the west of Ireland; however if the track of the low pressure is further east than currently expected, then these very strong winds may possibly affect our west coast.

The principal dangers from this weather system will be due to very high seas off the southwest and west coast (waves approaching 9m) and coastal flooding due to a combination of high tides, very low pressure, storm surge and onshore winds. The danger period extends through Sunday night and, for the east coast, much of Monday also. Valid from: 12hrs Sunday Nov 7th To: 06hrs Tuesday Nov 9th.

Householders, property owners, motorists and pedestrians are warned that there is a risk of coastal flooding in Dublin in the next 36 hours according to a Dublin city council update issued last night.

Dublin Bay

Dublin Bay on the east coast of Ireland stretches over seven kilometres, from Howth Head on its northern tip to Dalkey Island in the south. It's a place most Dubliners simply take for granted, and one of the capital's least visited places. But there's more going on out there than you'd imagine.

The biggest boating centre is at Dun Laoghaire Harbour on the Bay's south shore that is home to over 1,500 pleasure craft, four waterfront yacht clubs and Ireland's largest marina.

The bay is rather shallow with many sandbanks and rocky outcrops, and was notorious in the past for shipwrecks, especially when the wind was from the east. Until modern times, many ships and their passengers were lost along the treacherous coastline from Howth to Dun Laoghaire, less than a kilometre from shore.

The Bay is a C-shaped inlet of the Irish Sea and is about 10 kilometres wide along its north-south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sandbanks lie, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.

Dublin Bay FAQs

There are approximately ten beaches and bathing spots around Dublin Bay: Dollymount Strand; Forty Foot Bathing Place; Half Moon bathing spot; Merrion Strand; Bull Wall; Sandycove Beach; Sandymount Strand; Seapoint; Shelley Banks; Sutton, Burrow Beach

There are slipways on the north side of Dublin Bay at Clontarf, Sutton and on the southside at Dun Laoghaire Harbour, and in Dalkey at Coliemore and Bulloch Harbours.

Dublin Bay is administered by a number of Government Departments, three local authorities and several statutory agencies. Dublin Port Company is in charge of navigation on the Bay.

Dublin Bay is approximately 70 sq kilometres or 7,000 hectares. The Bay is about 10 kilometres wide along its north-south base, and seven km in length east-west to its peak at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south.

Dun Laoghaire Harbour on the southside of the Bay has an East and West Pier, each one kilometre long; this is one of the largest human-made harbours in the world. There also piers or walls at the entrance to the River Liffey at Dublin city known as the Great North and South Walls. Other harbours on the Bay include Bulloch Harbour and Coliemore Harbours both at Dalkey.

There are two marinas on Dublin Bay. Ireland's largest marina with over 800 berths is on the southern shore at Dun Laoghaire Harbour. The other is at Poolbeg Yacht and Boat Club on the River Liffey close to Dublin City.

Car and passenger Ferries operate from Dublin Port to the UK, Isle of Man and France. A passenger ferry operates from Dun Laoghaire Harbour to Howth as well as providing tourist voyages around the bay.

Dublin Bay has two Islands. Bull Island at Clontarf and Dalkey Island on the southern shore of the Bay.

The River Liffey flows through Dublin city and into the Bay. Its tributaries include the River Dodder, the River Poddle and the River Camac.

Dollymount, Burrow and Seapoint beaches

Approximately 1,500 boats from small dinghies to motorboats to ocean-going yachts. The vast majority, over 1,000, are moored at Dun Laoghaire Harbour which is Ireland's boating capital.

In 1981, UNESCO recognised the importance of Dublin Bay by designating North Bull Island as a Biosphere because of its rare and internationally important habitats and species of wildlife. To support sustainable development, UNESCO’s concept of a Biosphere has evolved to include not just areas of ecological value but also the areas around them and the communities that live and work within these areas. There have since been additional international and national designations, covering much of Dublin Bay, to ensure the protection of its water quality and biodiversity. To fulfil these broader management aims for the ecosystem, the Biosphere was expanded in 2015. The Biosphere now covers Dublin Bay, reflecting its significant environmental, economic, cultural and tourism importance, and extends to over 300km² to include the bay, the shore and nearby residential areas.

On the Southside at Dun Laoghaire, there is the National Yacht Club, Royal St. George Yacht Club, Royal Irish Yacht Club and Dun Laoghaire Motor Yacht Club as well as Dublin Bay Sailing Club. In the city centre, there is Poolbeg Yacht and Boat Club. On the Northside of Dublin, there is Clontarf Yacht and Boat Club and Sutton Dinghy Club. While not on Dublin Bay, Howth Yacht Club is the major north Dublin Sailing centre.
