Abstract
A pesar de la importancia e implicaciones de los riesgos asociados a la dinámica litoral en las zonas costeras, son escasos los trabajos centrados en su estudio y cartografía a escala regional, de manera sistemática e integrada. En este trabajo se presenta una metodología basada en el análisis detallado de los peligros naturales que pueden afectar al litoral: inundaciones, erosión costera, subida del nivel del mar, tsunamis, movimientos de ladera, etc., y en el estudio y cartografía de los factores implicados en su ocurrencia (geomorfología litoral, procesos litorales, sucesos históricos, actuaciones humanas…). Estos factores y peligros se evalúan e integran para la elaboración de un mapa final de susceptibilidad en el que se presenta la valoración tanto de cada peligro de forma individual, como del conjunto de los mismos. El sistema de representación cartográfica empleado, en franjas paralelas a la costa, facilita el reconocimiento e interpretación de las características del litoral estudiado y los peligros asociados. La metodología que se presenta ha sido aplicada a la zona litoral de la Región de Murcia, mostrándose de forma práctica su utilidad para el caso analizado y su posible aplicabilidad a otras regiones.
Despite the importance and implications of coastal hazards, very few studies have been focused on their analysis and mapping on a regional scale in a systematic and integrated way. This article presents a methodology based on the detailed analysis of natural hazards affecting coastal zones: floods, erosion, sea level rise, tsunamis, landslides, etc., and the study and mapping of the factors involved (coastal geomorphology, coastal processes, historical events, human activities…). These factors and hazards are evaluated and integrated to prepare maps which include the assessments of each individual hazard and the overall ones. A mapping system in strips parallel to the coast is used, allowing the recognition and interpretation of the characteristics of the coast and the associated hazards. This methodology is applied to the coastal zone of Murcia, showing its usefulness for studying and mapping coastal hazards and its applicability to other regions.
