Inundation scenarios of sea level rise due to climate change for Coco, Tamarindo and Samara Beaches, Costa Rica
Article Sidebar
Main Article Content
Sea level rise is analyzed based on the average high tide level for the North Pacific region of Costa Rica. This study was carried out based on models, observations and measurements made in the field, which present a sea level and its respective rise for four scenarios according to the following years: 2030, 2050, 2070 and 2100. Real scenarios are elaborated to simulate the behavior of the sea level in the next 100 years for the areas of Playas del Coco, Tamarindo and Samara. Astronomical tide levels are studied from tidal predictions. The sea level rise in the next few years due to global warming is according to the scenarios of Nerem et al., (2018) around 3 mm per year for the Pacific Coast in general and is used as a basis to create the different combinations and generate the tidal levels represented in this article. The results show the levels of flooding for each of the years for the study areas and indicate the communities that could be flooded by the year 2100 but happening increasingly in the rest of the years. This study aims to alert government institutions to these scenarios so that they can make appropriate decisions in the face of impending sea level change. Sea level combinations are proposed, so that other components not included in this study, such as tsunamis, can be simulated as well, and help in decision-making in the face of these possible events
