Técnicas numéricas y remotas para la gestión de playas: aplicación a un grupo de tormentas

Abstract

[ES] Se analiza la respuesta morfodinámica de una playa micromareal durante un grupo de tormentas y se detallan los efectos de cada evento individual a partir de modelización numérica, mediciones in situ e imágenes. La combinación de estas técnicas presenta una herramienta multiplataforma para la gestión de playas. En este trabajo, la respuesta morfodinámica se examina frente a un grupo de tres tormentas. La primera, de condiciones moderadas (Hs∼1 m durante 6 h), erosionó la playa seca y generó una barra sumergida en la zona de rotura. La barra fue desplazada hacia aguas profundas durante el segundo evento más enérgico (Hs = 3.5 m y 53 h). La tercera tormenta, similar a la primera, apenas afectó a la morfología de la playa, lo que corrobora la importancia de la configuración morfológica previa. Durante los meses siguientes, caracterizados por condiciones de baja energía, la playa seca recuperó la mitad del volumen de arena que perdió durante el paso del grupo de tormentas. El análisis de la evolución de la playa muestra dos escalas temporales diferentes para los procesos de erosión y recuperación asociados a las tormentas y las condiciones de calma, respectivamente. El trabajo también destaca la importancia de utilizar diferentes herramientas (vídeomonitoreo, modelado numérico y toma de datos in situ) para analizar la morfodinámica de las playas

[EN] The morphodynamic response of a microtidal beach under a storm group is analyzed, and the effects of each individual event are inferred from a numerical model, in situ measurements and video imaging. The combination of these approaches represents a multiplatform tool for beach management. Here, the morphodynamic response is examined during a period with a group of three storms. The first storm, with moderate conditions, eroded the aerial beach and generated a submerged sandbar in the breaking zone. The bar was further directed offshore during the more energetic second event. The third storm, similar to the first one, hardly affected the beach morphology, which stresses the importance of the beach configuration previous to a storm. During the following months, which are characterized by mild wave conditions, the aerial beach recovered half of the volume of sand that is transported offshore during the storm group. The analysis of beach evolution shows two different characteristic timescales for the erosion and recovery processes. The work also stresses the importance of using different tools to analyze beach morphodynamics
