Abstract

Sandy beaches around the world are under pressure from increased urban development and challenges posed by a changing climate. A common result of these pressures is coastal erosion which can pose a hazard to coastal communities and jeopardise the values of the coastal environment. This thesis develops numerical modelling techniques to better understand the climate drivers and pressures affecting sandy beaches, providing insights into the requirements of current and future coastal management strategies.

The research focuses on Adelaide’s managed beaches, where coastal structures and beach nourishment have been used to mitigate coastal erosion risk. The study's findings suggest that beach nourishment will remain a critical strategy but will require adaptation to address future challenges posed by sea level rise and shifts in climate drivers affecting seasonal wave conditions.
