ABSTRACT

The combination of the current sea level rise (SLR) and an increase in the frequency and severity of sea storm events and surges, will have important environmental impacts on coastal tourist areas located in oceanic islands that are often heavily dependent economically on tourism. Importantly, coastal tourist resorts and their associated beaches are commonly located in the S-SW of these islands where they are protected from the effects of the NE trade winds but exposed to these storms. This study analyses the current and future conditions of SW sea storm events. Then, through mapping using orthophotos, LiDAR data, and bathymetry with high spatial resolution, it studies the environmental effects that these events are having now and will have in the future on tourist zones of oceanic islands. This is of particular importance, as in the case of the Macaronesia islands, SW sea storm events are occurring with ever greater frequency. The case study considers the SW sector of the island of Gran Canaria (Canary Islands, Spain). Regarding the analysis of SW storms, the results obtained show an increase in the frequency of events, especially since the 1990s, with 104 events detected (67.5% between 1958 and 2018). The most affected areas during these storms are usually beaches (severe erosive processes). Breakwaters and seafronts usually resist the impact of waves well, however, as is discussed that in the future scenario, their implementation will mean a high economic cost for local administrations.
