Consequences of short-term changes in coastal processes : a case study

Auteur(s) et Affiliation(s)



Description :
In 1997-98, unique critical beach erosion led to structural failure along the Penarth, South Wales coastline. Anthropogenic activities, such as the construction of the Cardiff Bay Barrage and offshore marine aggregate dredging, were suggested as causes. The time-frame of significant erosion was between 1995 and 1997 and forcing agents (extreme sea level and wind direction) and shoreline indicators (mean beach level and Mean High Water) were analysed in order to assess change. Relationships showed correlation between forcing agents (extreme sea level and wind direction) and shoreline indicators. It was concluded that the critical erosion of Penarth beach between 1995 and 1997 was caused by increased wave attack generated by unique significant changes in wind direction and extreme sea levels.
