dc.description.abstractCoastal monitoring is fundamental to understand the morphological changes in coastal environments and the vulnerability of low-lying coasts to erosion and flooding. For this reason, this study was focused on monitoring coastal erosion in three areas distributed along the western region of Puerto Rico using small unmanned aerial vehicles (UAVs). These UAVs provided rapid-assessment and high-resolution images for shoreline monitoring from 2016 to 2018. The images served to establish a baseline aerial analysis useful to quantify the erosion rate using the Digital Shoreline Analysis System (DSAS) and computing the rate-of-change statistics of the coastal zones from multiple historic (1930 to 2010) shoreline positions. In addition, XBeach model was implemented to simulate swell events generated by Hurricane Matthew (Category 4) in 2016. The results demonstrated the synergy of low cost small UAV surveys and XBeach modeling to monitor the coastal zones and determine morphological changes in coastal environments.en_US
dc.description.abstractEl monitoreo costero es fundamental para comprender los cambios morfológicos en los ambientes costeros y la vulnerabilidad de las costas bajas a la erosión e inundaciones. Por esta razón, este estudio se enfocó en monitorear la erosión costera en tres áreas distribuidas a lo largo de la región occidental de Puerto Rico usando pequeños vehículos aéreos no tripulados (UAVs). Estos UAVs proporcionaron una evaluación rápida e imágenes de alta resolución para el monitoreo costero desde el 2016 al 2018. Las imágenes sirvieron para establecer un análisis aéreo de referencia, útil para cuantificar la tasa de erosión usando el Sistema Digital de Análisis de Litoral (DSAS) y calcular la tasa de cambio estadísticas de las zonas costeras a partir de múltiples posiciones históricas (1930 al 2010) en la costa. Además, se implementó el modelo XBeach para simular los eventos de oleaje debido al huracán Matthew (Categoría 4) en 2016. Los resultados demostraron la sinergia del uso de UAVs de bajo costo y el modelaje en XBeach para monitorear las zonas costeras y determinar los cambios morfológicos en ambientes costeros.en_US
