We applied the MOHID (MOdelo HIDrodin??mico) physically-based numerical model forced with data from tide gauges located in the mouths of the two bays, which were validated with current and tide measurements inside the bays. This is the first study to use numerical modelling in Santa Catarina Island Bays to predict the influence of bivalve mollusc biodeposit areas. The simulated scenarios suggest that the widest dispersion zones occurred during the spring tide when particles were deposited over a 24 km2 area corresponding to, approximately, 5.5% of the total bay area. The maximum concentration of biodeposits was 50 particles.grid cell−1 and it occurred within a ~4.8 km2 zone. Current velocities were simulated for sheltered and exposed sites and for neap and spring tides in the North and South Bays. aBays of Santa Catarina Island abiodeposit abivalve mollusc aMOHID1 aGARBOSSA, L.
