playa de bloques; Galicia; variaciones costerasResumen
Las mejoras tecnológicas que se han producido en las últimas décadas han supuesto un gran avance en el conocimiento del dinamismo de las zonas costeras. La presente investigación se ha centrado en una playa de bloques de 400 m de longitud situado en la costa sur de Galicia. En 2016 se introdujeron en 80 bloques sensores de radiofrecuencia (RFID) con objetivo de conocer sus vectores de movimiento a nivel individual. A partir de esa fecha y tras 8 campañas de seguimiento sobre el terreno, se han detectado desplazamientos de hasta 38 m en bloques de más de 140 kg. Esta investigación muestra el potencial de esta metodología para analizar las dinámicas costeras y la posibilidad de relacionar los cambios con los factores oceánicos (intensidad y recurrencia de los temporales marinos) y continentales presentes. Se ha demostrado la utilidad de estos sensores en sectores dinámicos como las playas de bloques y se ha evidenciado una reducción de las tasas de desplazamiento vinculadas frecuentemente al enterramiento de los bloques monitorizados o al bloqueo de estos.
