Numerical simulation of the hydrodynamics of a port and effect of a wave-driven seawater pump

A three-dimensional numerical model was adapted to study the circulation, stratification and mixing patterns inside the port of El Sauzal. Salinity, temperature and density field data were measured, showing that density variations were mainly due to the temperature field with a very small contributi...

Salinity, temperature and density field data were measured, showing that density variations were mainly due to the temperature field with a very small contribution from salinity. The model simulated surface currents and the temperature field. The simulation was compared against field data showing that the model reproduces satisfactorily the circulation, stratification and mixing patterns. Surface circulation and vertical mixing were mainly forced by the tide, although winds greater than 6 m s–1 became the main forcing of vertical mixing and surface circulation. The surface currents traveled outside the port during ebb tide and vice versa during flood tide; however, with winds greater than 6 m s–1, the surface velocity followed the wind direction. When a discharge of 0.2 m3 s–1 was introduced into the system, the simulation showed an increase of 0.5 cm s–1 in the surface current velocity, during ebb tide. The vertical temperature structure increased as much as the discharge temperature (17.2ºC). This result verifies that a controlled discharge could improve circulation and mixing, reducing the residence time and improving the levels of oxygen in the water. Con la finalidad de conocer el patrón de circulación, estratificación y mezcla dentro del puerto de El Sauzal, se adaptó un modelo numérico tridimensional. Paralelamente se obtuvieron datos hidrográficos en el puerto de El Sauzal, en los que se encontró a la temperatura como el agente que modifica el campo de densidad, ya que la salinidad tiene poca variación en este sistema. Debido a lo anterior, el modelo simuló solamente el patrón de distribución de temperatura y corrientes. La simulación fue validada con datos de campo, demostrando que el modelo reproduce adecuadamente el patrón de circulación, estratificación y mezcla. El principal forzamiento de la circulación superficial y mezcla vertical en este sistema fue la variación del nivel de mar; sin embargo, el viento superior a 6 m s–1 se convirtió en el principal forzamiento del patrón de circulación y mezcla. Durante la bajamar la dirección de la corriente superficial fue hacia afuera del puerto y viceversa durante la pleamar; sin embargo, cuando el viento tuvo velocidades superiores a 6 m s–1, la dirección de las corrientes siguió la dirección del viento. Durante la bajamar, al introducir una descarga de 0.2 m3 s–1 al sistema, la simulación presentó un incremento de 0.5 cm s–1 en la velocidad de las corrientes superficiales. La estructura vertical de temperatura presentó un incremento generalizado hasta igualar la temperatura de la descarga (17.2ºC). Este resultado indica que una descarga controlada puede ser capaz de mejorar la circulación y mezcla, lo que podría reducir los tiempos de residencia y mejorar los niveles de oxígeno en el agua. 2005-03-06 2021-06-03T03:54:54Z 2021-06-03T03:54:54Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Artículo Arbitrado https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/78 10.7773/cm.v31i11.78 https://hdl.handle.net/20.500.12930/7321 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/78/58 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 31 No. 1A (2005); 57-77 Ciencias Marinas; Vol. 31 Núm. 1A (2005); 57-77 2395-9053 0185-3880
