Numerical simulation of marine currents in Sabana-Camagüey ArchipelagoAbstract
Debido al creciente desarrollo de los diferentes sectores industriales en el archipiélago de Sabana-Camagüey es necesario un grado mayor de especificidad en la descripción de las corrientes marinas y la dinámica costera para esta zona, lo cual condujo a desarrollar esta investigación. Con este objetivo, se utilizó el modelo numérico regional ROMS_AGRIF (Adaptive Grid Refinement in Fortran), el cual es una versión del modelo ROMS (Regional Ocean Model System), con el objetivo de simular las corrientes marinas considerando el efecto de la marea astronómica en la zona del archipiélago Sabana-Camagüey. Como resultados, se asimiló correctamente el modelo hidrodinámico ROMS_AGRIF para la zona de estudio, obteniéndose una implementación válida del comportamiento de las corrientes marinas para toda el área del archipiélago Sabana Camagüey. Se seleccionó una configuración adecuada para el cálculo de la marea mediante 10 constituyentes fundamentales, aunque es posible mejorarla incluyendo los armónicos de bajo fondo y se obtuvieron buenos resultados en las simulaciones con un error de menos del 30 % de valores medidos, concordando así con las mediciones directas en el área de estudio.The increasing development of different industrial sectors in Sabana-Camagüey Archipelago has demanded a greater degree of specificity in the description of marine currents and coastal dynamics for this zone, which led to developing this investigation. For the aforementioned purpose, the numerical regional model ROMS_AGRIF (Adaptive Grid Refinement in Fortran), a version of the model ROMS (Regional Ocean Model System), was used for simulating marine currents, considering the effect of astronomical tides in Sabana-Camagüey Archipelago. As a result, the hydrodynamic model ROMS was accurately assimilated, achieving a good performance. A valid implementation of the behavior of marine currents for Sabana-Camagüey Archipelago area was obtained through this model. An adequate configuration for computing tides was selected, based on 10 fundamental constituents; although it could be improved by including near-bottom harmonics. Good results were achieved regarding marine current simulations, since for most of the computed values, the error represented less than 30% of the measured values, being in accordance with punctual measurements in the study area.
