A: the vertical difference between high and low tide at a given point.
Living in the UK and with 11,072.76 miles (17,820 km) of tidal coastline we know that the tidal reach, or range, can be significant in some places. One such place is the North Norfolk Coast. This is an area of outstanding natural beauty and bird watching capital of the UK. It consists of mainly coastal marshes, soft cliffs, beaches, dunes and mudflats. The coastline is mainly undeveloped and includes intertidal areas, towns and villages. Here is a typical North Norfolk view:
Stunningly beautiful, so I think it is rather a pity that my next watercolour failed to quite capture anything of that beauty. It is entitled ‘A Tidal Reach, North Norfolk’. It is signed by Ida Cubitt and was once for sale at £25. Did someone buy it as a souvenir I wonder?
