Numerical modeling of the tidal exchange through the Strait of Gibraltar
Abstract
The three-dimensional Princeton Ocean Model is used to investigate the tidal flow and the hydraulics regime in the Strait of Gibraltar. The model makes use of a vertical sigma coordinates and curvilinear orthogonal grid that include the Gulf of Cadiz and the Alboran Sea in a very high-resolution configuration (< 500 m). The model is forced through the specification of the tidal elevation at the western and eastern open boundaries; in particular the M2, S2, K1 and O1 tidal constituent are considered. After a first phase of model validation, in which we have positively compared experimental cotidal map with model cotidal map for each tidal constituent, a study of tidal transports have been carried out obtaining new interesting results. The hydraulic regime is also analysed, calculating the composite Froude number for three layers within the strait.
