dc.description.abstractThe Regional Ocean Modeling System has been implemented in the San Juan bay estuary, Puerto Rico, to investigate quantitatively the ocean currents at a harbor scale with tidal, wind and river forcing and to develop a forecast system to support emergency planning and resource management in the area. A hind-cast simulation is performed and compared with measurements from an acoustic Doppler current profiler and tide gages to validate the numerical model. Good agreement has been found with coastal observations of sea surface height and time series of the velocity. From a statistical analysis it is found that the numerical model has a 60 percent of prediction accuracy. To investigate the impact of river discharge inside the San Juan bay a numerical experiment of the response to river discharge is performed and compared with the wind and tidal forcing only. Results show how the salinity distributions is affected by fresh water discharge inside the bay when the river is present. Small differences are observed in the sea surface velocity, however, barotropic velocity does not get affected by the river.
dc.description.abstractEl sistema de modelaje oceánico regional (ROMS) ha sido implementado en la bahía de San Juan, Puerto Rico, para investigar cuantitativamente los procesos oceánicos del área a una escala de puerto forzando el modelo con mareas, vientos y ríos, y que al mismo tiempo sea utilizado como herramienta de pronostico que pueda ayudar en manejo de emergencias y recursos del área. Se realizo un análisis retrospectivo de las corrientes y fueron comparadas con mediciones en el tiempo de datos hidrográficos para validar el modelo. Buena correlación se ha encontrado con mediciones de mareógrafos para la elevación del mar y series de tiempo de velocidad. Haciendo un análisis estadístico se encontró que el modelo numérico tiene un 60 porciento de precisión en pronostico. Un experimento numérico se realizo para investigar la respuesta de las corrientes dentro de la bahía a la descarga de agua fresca en conjunto con esfuerzo de marea y vientos y se comparo con una simulación donde la descarga de río no estaba presente. La distribución de salinidad vertical y horizontalmente se ve afectada, sin embargo el impacto en las corrientes es menor, además que ningún impacto se observo en las velocidades barotropicas.
