Estuary and Coastal Ocean Model (ECOM), a 3D ocean model using orthogonal curvilinear grid, was developed and modified in order to accommodate an application of velocity boundary condition together with existing water-level boundary type. The aim of this modification is to get better understanding of hydrodynamics circulation at Benoa Port, Bali. The simulation results show a good agreement with observation data. Results of the model showed currents flow into the port at flood and out at ebb. Currents along port canal are dominated by east-west component with magnitude of 0.5-0.8 m/s and in the open sea the currents dominantly flow southward. Outside the port, directions and magnitudes of velocities are vertically varies. Meanwhile, the directions of velocities are uniform and its magnitude decrease to the depth inside the port. Temperature distribution from near-surface in port to 50 m depth offshore changes from 27.4 oC to 24.3 oC. At flood, high salinity water from deep water (34.21 psu) moves into the shallow area inside the port, while at ebb, low salinity water (34.19 psu), moves back to the open sea. <br />
