[Article] Engineers planning dam to protect Dublin from floods

    ENGINEERS are considering an elaborate dam system (pictured left) in the centre of Dublin Port to fend off the worst effects of global warming.
    Under the proposals, a series of tidal gates would be erected between the end of two piers stretching into Dublin bay, in an attempt to stop the flooding of the quays in Dublin city centre as part of a "worst case scenario" study.
    However, there are no costings available for the plans and works are not expected any time in the near future.
    Dublin City Council said it estimated that it would be 2050-2080 before the effects of global warming would warrant the measures in the capital.
    Yesterday Tom Leahy, an executive manager in Dublin City Council, said the eight-metre high moveable walls would be situated between the Poolbeg lighthouse and the North Bull lighthouse and would be supported by a number of columns.
    The walls, which are also being examined by Dutch engineers, would break the energy of a barrage of waves coming into the bay and prevent serious damage further up the river into the centre of the capital.
    "With rising sea levels and more energy and instability in the weather, you are going to get much stronger seas. As a defence strategy for those, you can't rely solely on a shoreline defence," said Mr Leahy.
    Dublin City Council has spent some €80m on flood relief in the capital over the last six years following the worst flooding in the history of the state in 2002.

    Thames Barrier clone incoming... anyway, wasn't much of the worst flooding DCC have had to deal with both outside the area covered by the walls or caused by rivers anyway?

    The solution here would be to build a causeway across the bay from somewhere in the region of Sutton to Booterstown. We could build the eastern bypass from the tunnel atop the southern section and it would open up many other transport and infrastructure opportunities. It would also facilitate filling in the bay out to the causeway creating a proper seafront in Dublin bay. :cool:

    It would also completely destroy a large bird sanctuary IIRC ;)

    OK - so an additional benefit :D.

    But, point is, if sea level rises the bird sanctuaries (Booterstown, Bull Island etc) will be drowned anyway. Might have a chance with the causeway.

    Ye either believe in Global Warming and sea level rise or ye don't. Can't have it both ways :).
