ST4677 : Silt erosion
near to Portishead, North Somerset, Great Britain
Silt erosion
South of Port's Head the beach erodes slowly, William Carter researched this for a dissertation, but the extent of vegetation decline (marram grass) and the chemical, ship wash and storm wave pattern changes and the diverted sewer overflow and retained lake overflow have added to the rainfall offshore drainage and the backwash from tidal inundation and onshore swell. The offshore is lethal quicksand and steep, to one of the five fastest ebb flows, extremely dangerous. The history of Portishead beaches is gradually being revealed near the shore esplanade top side. 14:26 tide.
