Increase in the Erosion Rate Due to the Impact of Climate Change on Sea Level Rise: Victoria Beach, a Case Study

This article provides a general methodology for calculating the retreat of coastline and volume sand necessary to renourish beach due sea level rise (SLR) in medium-long term. An example is presented, Victoria Beach, projection made years 2030, 2040, 2050, 2100. The results obtained take into account global (GSLR), which worldwide, local (LSLR), considers climate variability vertical land movements. Regarding GSLR, data were provided by projections from IPCC (Intergovernmental Panel on Climate Change) scenarios empirical models, such as Rahmstorf Pfeffer. LSLR came tide gauge station located Cadiz. Finally, showed that warming impacts erosive effects subsequent required beaches. total (TSLR) indicated Beach are relatively higher than GSLR projections. Even best scenario (RCP 2.6), presents significant erosion 52 m, requiring 1.0 Mm3 supply renourishment.
