An implication of sea-level rise on Gnejna bay, Malta

Abstract

My dissertation deals with the impacts of sea-level rise on the coast and the change in beach equilibrium focusing on Gnejna beach in North West Malta. The Bruun rule model is used to show the change in beach profile after a global sea level rise scenario taken from the IPCC and a Mediterranean prediction taken by Marta Marcos. Data collection on site was taken during the summer period as construction of the beach is at its best and clarity of sea water was appropriate to obtain certain readings. There are four main factors associated with the Bruun rule. These are shore elevation, limiting depth between predominant nearshore and offshore material, sea-level rise and distance to limiting depth from shore.
