Protecting Pembrokeshire's Coastline

          Pembrokeshire South East Energy Group's May meeting followed the theme of flooding by looking specifically at the risk to our coastline.

          The Group was delighted to welcome Emyr Williams Pembrokeshire's Coast Protection Engineer to explain the current thinking on this issue.

          As the levels of CO2 in the atmosphere reach levels of 400ppm (not been above 300ppm over the last 800 thousand years) the resulting sea level rising oceans is being seen in a number of ways. A number of factors are contributing to this:

  • Ice is being lost from glaciers and ice sheets from Geenland, the Antarctic and the Himalyas as well as many other places around the globe.

  • Increases in the winds around the Antarctic brings warmer water to the area speeding up the process.

  • The increase in the upper ocean heat expands the sea water.

          These have contributed to a significant increase in the global sea level which has been accelerating over the last 20 years.

          Emyr explained that the Shoreline Management Plan (SMP) had now been signed off. The one covering our locality is the Lavernock to St Ann's Head area. Something like 90% of this will not be affected as it is hard rock. The problems are in areas where populations live or where infrastructure runs close to the sea roads (Amroth, Newgale) and railway lines.

          The risks are set out for 1 to 20, 20 to 50 and 50 to 100 year epochs. The maps showed the intention to take 'no active intervention, hold the (existing defence) line, managed realignment and advance the line'.

          The SMP can be seen at:

          In Penally and Tenby there is time for managing the realignment. Interestingly Emyr pointed out that the sand in South Beach is moving from West to East. Amroth and Saundersfoot both show as short and medium time 'hold the line' but managed realignment would be the long term plan.

          Following his talk a large number of questions were asked from people directly affected by these plans. Tenby sand dunes(half lost already), the Fisherman's Chapel (should be ok with just the occasional flooding Emyr suggested a solid floor and all electrics installed above any flooding risk). There are huge costs involved in all the schemes and a need to accept that everywhere cannot be protected in the long term.

          Emyr was thanked by the Chair. It is always good to hear an expert speaking with such authority on this topic and although he may have been giving a message which we could well not like to hear it is very important that it is given.
