AB Lagrangian experiments of particle tracking were carried out in the semi-enclosed Bay of Algeciras attachedto the Strait of Gibraltar in order to investigate the flushing patterns. A high resolution three-domain-nestedhydrodynamic model provided the velocity fields from a 61-d hindcast, with the aim of analyzing the flushingefficiency of eight different docks under a variety of external conditions, namely, tide phase and strength, andwinds. The tracking algorithm was specifically developed to exploit the high spatial resolution of the modelthat reproduces the local dynamics accurately. Winds are the dominant agent, with westerlies featuring e-foldingtimes one order of magnitude lower than easterlies. Fortnightly tidal modulation causes a counter-intuitiveeffect, with spring tides promoting higher accumulation of particles inside the docks and higher e-folding timesthan neap tides. Additionally to high resolution details on the flushing patterns of the Algeciras Port, themodel also confirms the Bay as a potential feeder of floating tracers for the nearby Alboran Sea. The proposedapproach is easily scalable and exportable to other similar locations worldwide.
