Semi-Analytical Model for the Evaluation of Shoreline Recession Due to Waves and Sea Level Rise

The climate change process is leading to an increase in the sea level and storm intensity. associated shoreline recession can damage coastal facilities also beaches protected by submerged/emerged breakwaters whose defense action become ineffective. application of cross-shore numerical models does not allow performance long-term analyses. In this paper, a semi-analytical model for evaluation due waves sea-level rise free proposed. extension Dean’s approach which some limitations on beach profile are overcome effects wave height (wave transmission) water (piling-up) considered. takes into account wide range parameters wave, level, profile, breakwater characteristics. Among parameters, freeboard berm width found mainly affect recession. For submerged breakwaters, optimal value be computed depending offshore results then used find prediction relations recession, with r2 > 0.99, both beaches, main hydrodynamic/geometrical
