Abstract
Esta monografía presenta el estado del arte de los modelos conceptuales de evolución morfodinámica de las playas. El objetivo de estos modelos es relacionar las condiciones ambientales (oleaje y mareas, tipo de sedimento), con las formas tridimensionales y la dinámica de las playas. En primer lugar se presenta los modelos conceptuales de Wright y Short (1984), desarrollados a partir de observaciones en playas micromareales. A partir de dichos modelos se expone el concepto de estado modal de una playa y la relación existente entre los estados de playa y el parámetro adimensional de caída de grano, que permite ligar las variaciones del oleaje y tipo sedimento con la evolución de los estados de playa. Por último, se introduce el efecto de la carrera de marea, siguiendo la investigación de Masselink y Short (1993). Como resultado, el modelo conceptual de evolución morfodinámica, presentado por Wright y Short (1993) permite determinar la distribución de estados de playa en función de la distribución del parámetro adimensional de caída del grano y de la carrera relativa de marea.
