Optimization of Breakwater Design Under the Effect of Sea Level Rise

Abstract

In this work, the impact of sea level rise due to climate change on breakwaters was evaluated by comparing current design conditions with four sea level rise scenarios. An optimization algorithm based on a Black Hole model was developed for the design of armor elements, analyzing the effect of each increase in the design of such elements within a control point in the breakwater, comparing the results obtained with and without restrictions in the dimensions of each element. A first approximation was obtained to evaluate the effect that different scenarios due to climate change have on the traditional conditions and the degree of impact expected in a breakwater to optimize the design of the armor elements having as target variable the weight and volume of concrete. Differences of up to 22,08% were obtained between the traditionally calculated values and those obtained using the Black Hole algorithm.
