      Didn't get as far as the Mump today, pants weather.

      But I did get a few shots from the hill in Langport.

            'Sea level' datum (AKA national vertical datum) on UK maps is the halfway mark between high and low tide at Newlyn, Cornwall (which has the UK's lowest tidal range) so ground levels can be above that but below high tide level, especially around the Bristol Channel (which has the world's second highest tides). The datum at Newlyn (ODN) was measured between 1915 & 1921 and average sea levels are supposed to have increased since then. There's also the raising effect of low pressure.

            Tide heights relate to local chart datums level (lowest sea level at low tide. High tide today (Sat 1st Feb) is 12.00m at Burnham on Sea and it's 12.10m tomorrow. To get an idea how those heights relate to OS map levels requires the OS level at chart datum for Burnham on Sea. Anybody got that information (or the OS level for charted high water) ?

            I think many journalists just copy information into their reports without understanding it.

                Funny, when i was driving around the UK, you get to see things going on(Yes i like looking over the hedges being noses), many times i would go to the fens and you always sore diggers working on the waterways, but when you go to Somerset you wouldn't see any thing going on, do the fens flood like somerset, NO

                  Assuming the sea goes down to the same level on lowest tides at both Newlyn & Burnham, on Sea, and using the 6.00 tidal heights at Newlyn for today & tomorrow, that would mean high water at BoS would be 6.00m (12m - 6m) above OS datum today & 6.10m tomorrow (12.1 - 6m). If average sea levels have risen 180mm in the last hundred years, it will add about 173mm as the OS datum was calculated between 1915 and 1921.

                  That would mean high tide at BoS today would be 173mm above anywhere on the levels 6m 'above sea level' (above average sea level at Newlyn nearly 100 years ago) and tommorow would be 273mm above. Plus there's any additional sea height caused by both low pressure and onshore winds. And there's bigger spring tides in the Bristol Channel than today.

                          At least there's no more perigean tides this year.

                              We still seem to have got away with this weather in West Cheshire, or at least where I am. We're sitting above the Cheshire Plains and have some great views, while the River Weaver is at the bottom of a hill about 100' below. Also we're lucky, although I sometimes curse it from the gardening point of view, because the soil is very sandy and free draining around here.......although we've still got a lot of water holding in the fields.:coffee::snork: So while we've had a lot of rain and wind we're not suffering like those towards the West Welsh/Cheshire Coast.:dunno:
