Shorelines | Las líneas de costa
Figura 1: Líneas de costa históricas de Puerto Rico, disponibles en el Portal de Riesgos por Cambios Costeros del USGS.
Historical shoreline positions were determined for Puerto Rico from 1901 to 2018, using historical maps, aerial photographs, high resolution satellite imagery, and lidar (Light Detection and Ranging) data. Rates of change were measured with the Digital Shoreline Analysis System (DSAS), which calculates statistics from multiple historical shoreline positions. The goal of this project was to develop the existing USGS shoreline database in Puerto Rico. Data are available to download in the USGS Coastal Change Hazards Portal.
Las posiciones históricas de las líneas de costa fueron determinadas para Puerto Rico entre 1901 y 2018 usando mapas históricos, fotografías aéreas, imágenes satelitales de alta resolución y datos de lidar (detección de luz y alcance). Los rangos de cambio se midieron con el Sistema de Análisis Digital de la Costa (DSAS, por sus siglas en inglés), que calcula las estadísticas de distintas posiciones históricas de la costa. El objetivo de este proyecto era desarrollar la base de datos actual del USGS en las costas de Puerto Rico. Se puede descargar la información en el Portal de Riesgos por Cambios Costeros del USGS (Coastal Change Hazards Portal).
Coral Reef Assessments | Las evaluaciones de los arrecifes de coral
Figura 2: Arrecife de coral en La Parguera, Lajas, Puerto Rico.
USGS has a published a variety of research regarding coral reefs in Puerto Rico, covering topics such as the value reefs for flood risk reduction, a comparison of pre-storm and post-storm flood levels, hurricane impacts on coral reefs, and possible benefits of coral reef restoration scenarios to mitigate coastal hazards. Summary reports can be accessed in the links below:
El USGS ha publicado una variedad de investigaciones con relación a los arrecifes de coral en Puerto Rico que abarcan temas como la importancia de los arrecifes para la reducción de los riesgos de inundación, una comparación de los niveles de inundación antes y después de una tormenta, el impacto de los huracanes en los arrecifes de coral y los posibles beneficios de la restauración de arrecifes para mitigar los peligros costeros.

Dune Impact Probabilities | Las probabilidades del impacto de las dunas
Another ongoing project is focusing on estimating projections of wave impacts on sand dunes to determine the probability that waves will erode, overtop, or completely inundate dunes for generalized category 1-5 hurricane conditions. This approach is also called probability of Collision, Overwash, and Inundation (pCOI). Coastal features were extracted from lidar information. Results will be available for Puerto Rico in the USGS Coastal Change Hazards Portal.
Otro proyecto actual se centra en estimar las proyecciones del impacto de las olas en las dunas de arena para determinar la probabilidad de Colisión con la duna, Desborde sobre la duna e Inundación de la duna (pCOI, por sus siglas en inglés) a fin de evaluar las probabilidades de que las olas produzcan erosión, sobrepasen o inunden por completo las dunas en el caso de los huracanes de categoría de 1 a 5. Las características de las costas se extrajeron de la información del lidar. Los resultados para Puerto Rico estarán disponibles en el Portal de Cambios Costeros del USGS (USGS Coastal Change Hazards Portal).
