Resumen
Se aplica la modelación físico-matemática para caracterizar la propagación del oleaje y las corrientes generadas por este en condiciones extremas en la bahía de Cienfuegos y el sector costero correspondiente a playa Rancho Luna. La zona de la bahía constituye, un elemento concluyente en el desarrollo industrial de toda la región del país, en su márgen se ubican numerosas instalaciones de gran valor para el desarrollo petroquímico, industrial y portuario del lugar; además de la mayor parte de la ciudad. Al mismo tiempo, la playa Rancho Luna constituye el espacio de recreación privilegiado del municipio cabecera, al cual arriban en el verano ciudadanos de toda la región central del país. También se encuentra en el contexto de desarrollo del polo turístico Cienfuegos – Trinidad, con lo cual se significa el arribo de turistas extranjeros en una cifra creciente y por lo tanto su importancia socioeconómica.; en ella también se encuentran infraestructuras de gran valor como hoteles, restaurantes, entre otras. Estas instalaciones se encuentran en áreas expuestas al impacto destructivo del oleaje extremal, por lo que es de vital importancia conocer la magnitud del mismo, así como la dirección de las corrientes que genera, para implementar medidas de protección y prevención. En el conjunto de investigaciones realizadas hasta este trabajo en estas aéreas en relación a la caracterización del oleaje, queda por resolver cual es la interacción entre este fenómeno, el oleaje y las corrientes generadas por el mismo y aquellas que se producen por la marea y los aportes fluviales, principales motores del movimiento en estos sistemas. Por lo cual el objetivo de este trabajo es la realización de una modelación físico-matemática que permita caracterizar estos fenómenos, obteniéndose información sobre las principales magnitudes que los caracterizan como altura de onda, magnitud y dirección de las corrientes, etc. Para lograr esto se aplica la herramienta informática Sistema de Modelado Costero (SMC), con el cual se logra determinar las variables de interés que permiten conocer el comportamiento del oleaje y las corrientes que este provoca en función de la intensidad del huracán que afecte la zona.
Physical-mathematical modeling is applied to characterize the propagation of the waves in the sea and the currents generated by these in extreme conditions in the bay of Cienfuegos and the coastal sector corresponding to Rancho Luna beach. The area of the bay is a conclusive element in the industrial development of the entire region of the country. There are numerous facilities of great value for the petrochemical, industrial and port development of the area; in addition to most of the city. At the same time, the Rancho Luna beach constitutes the privileged recreation area of the Cienfuegos municipality, to which the citizens of the entire central region of the country arrive in the summer. It is also in the context of the development of the Cienfuegos - Trinidad tourist center, which means the arrival of foreign tourists in a growing number and therefore their socioeconomic importance. In it are also infrastructures of great value as hotels, restaurants, among others. These installations are located in areas exposed to the destructive impact of extreme waves, so it is of vital importance to know the magnitude of the same, as well as the direction of currents generated, to implement protection and prevention measures. In the set of research carried out up to this work in these areas in relation to the characterization of the waves, it remains to be resolved what is the interaction between this phenomenon, the waves and the currents generated by it and those produced by the tide and the fluvial contributions, the main engines of movement in these systems. Therefore, the objective of this work is the realization of a physical-mathematical modeling to characterize these phenomena, obtaining information on the main magnitudes that characterize them as wave height, magnitude and direction of currents, etc. In order to achieve this, the computer tool Coastal Modeling System (SMC) is applied, with which it is possible to determine the variables of interest that allow to know the behavior of the waves and the currents that this provokes depending on the intensity of the hurricane that affects the zone .
