摘要

This paper investigates on applying the three-dimensional hydrodynamic SHYFEM model to explore and analyze the spatial interactions between the Nador Lagoon and its surrounding environment in the Alborán Sea. This study offers an overview of the region and applies a three-dimensional hydrodynamic model to investigate the circulation and water exchange dynamics between the lagoon and the surrounding marine environment. The external forcing variables include tide and meteorological conditions, as well as temperature and salinity boundary conditions. The validity of the simulation results was assessed through comparison with field measurements. The model was run for a year to examine the evolution of the temperature and salinity over time, considering multiple scenarios for temperature and salinity parameters across various lagoon regions. The simulated monthly salinity and the temperature show an increase from winter to summer, influencing by the exchange process between the sea and the lagoon. The enclosed areas are more influenced by meteorological conditions, while the inlet and the center of the lagoon are mainly affected by seawater.
