Design of an artificial reef for coastal protection and wave generation

Abstract

This study explores the feasibility of implementing an artificial surf reef (ASR) on the north coast of Gran Canaria as a dual-purpose solution to mitigate coastal erosion and enhancing surf conditions. After a bibliographic review, the research evaluates maritime climate, coastal morphology and existing ASR designs for an adaption on a volcanic island. Numerical simulations were performed to assess the changes in each scenario and being able to perform a subsequent analysis of the resulting wave. Results confirm that the ASR promotes wave breaking further away from the shore, reducing energy impact on this coastal stretch and generates surfable waves with variable characteristics, depending on swell conditions. The project also discusses socio-economic implications, highlighting the potential to create a sustainable tourism, also comparing it to energy-intensive alternatives such as wave pools, the ASR stands out as a low-energy, climate-conscious intervention.
