In this study we have applied a hydrodynamic numerical model of Lagrangian tracers to study the dispersion and subsequent settlement of particles from two different points of emission. The main objective was to define whether the particles, within the sedimentation period, could be exported out of the Anegada Bay (Argentina). We obtained the distance traveled by the particles, transported by currents induced by the tide and wind, and determined possible settlement areas. It was concluded that particles released from two different points do not leave Anegada Bay boundaries.


Key words: MOHID, modelo hidrodinámico, circulación
