Resumen
La erosión del perfil del acantilado es la pérdida progresiva de material rocoso como consecuencia de la interacción de factores ambientales (olas, vientos y lluvias) y geo-mecánicos (características del suelo y roca) propios de la zona. Es una problemática geo-ambiental que afecta a las comunidades costeras, cercanas a estas formaciones y constituye un riesgo para la vida de los habitantes y sus bienes. La erosión es uno de los principales agentes modificadores del borde costero. En los acantilados, la acción erosiva de las olas provoca socavaciones al pie del talud y consecuentemente por efectos gravitacionales, el desprendimiento de masas de material rocoso. Además, la acción del viento y las precipitaciones generan inestabilidad en los taludes ocasionando deslizamientos del material rocoso o del suelo. Los factores que influyen en los riesgos de erosión costera son de vital importancia para la gestión de costas, el desarrollo de modelos predictivos es crucial.
The erosion of the cliff profile is the progressive loss of rock material because of the interaction of environmental factors (waves, winds and rain) and geo-mechanical factors (soil and rock characteristics) typical of the area. It is a geo-environmental problem that affects the coastal communities, close to these formations and constitutes a risk to the lives of the inhabitants and their property. Erosion is one of the main modifying agents of the coastline. On the cliffs, the erosive action of the waves causes scour at the foot of the slope and consequently, due to gravitational effects, the detachment of masses of rock material. In addition, the action of the wind and the precipitations generate instability in the slopes, causing landslides of the rocky material or the soil. The factors that influence the risks of coastal erosion are of vital importance for coastal management, the development of predictive models is crucial.
