About this event

The winters of 2012 to 2014 were some of the wettest on record. 2012 included the longest sustained period of wet weather for 254 years. Gales generated large and ferocious storm waves that impacted sea cliffs and structures, many being exposed to the full fury of sea wave attack. Notable local structures affected included Dawlish Sea wall in Devon and Kingsand Clock Tower and Institute Building in Cornwall.

Hydrostatic pressures induced in slopes and cliffs by the exceptional prolonged rainfall, triggered instability. Breaking storm waves generated by winds sometimes in excess of gale force, induced extreme pneumatic pressures into both fractured rock sea cliffs and shoreline construction. There have been many examples of structural failures due to the generation of pneumatic pressures in recent years.

An explanation of critical geological and structural features which can expose a shoreline construction and geology to damaging wave impact are presented and discussed in this lecture hosted by ICE South West’s Plymouth City Club.  The presentation will be given by Dr John Grimes of John Grimes Partnership Ltd.  An ICE Fellow, John first became interested in this subject in 1974 after observing the substantial damage caused by pneumatic wave action induced in a sea wall at Weston-Super-Mare.

Please note this is a face to face event.
