Prigi Bay is a semi-enclosed coastal system where tidal hydrodynamics govern circulation patterns and constitute the dominant hydrodynamic forcing within the bay. The purpose of this study is to model tidal circulation characteristics and evaluate their implications for fisheries-port management in Prigi Bay, Trenggalek Regency, East Java, Indonesia. Tidal currents were simulated using the Advanced Circulation (ADCIRC) model and supported by in situ current measurements conducted through purposive sampling and Eulerian observations using current meters, while tidal characteristics were derived using harmonic analysis based on the Admiralty method and model outputs. The results indicate that Prigi Bay has a mixed predominantly semidiurnal tide. Station-representative observed current velocities ranged from 0.10 to 0.34 m s⁻¹, while individual field measurements reached up to 0.50 m s⁻¹. ADCIRC simulations produced current velocities of up to 0.63 m s⁻¹ during the simulated tidal cycle. The Admiralty analysis yielded HHWL at +1.32 m and LLWL at −1.32 m relative to MSL, whereas the ADCIRC simulation produced a maximum water level of +1.15 m and a minimum of approximately −1.09 m during the simulation period. The model showed a mean relative error of 7.18% for tidal elevation, indicating good agreement with field observations. The simulated circulation patterns suggest that the narrow bay entrance and gently sloping bathymetry influence the spatial distribution of tidal currents within the bay. These findings provide a hydrodynamic baseline that can support coastal zoning, navigation planning, and fisheries-port management in Prigi Bay.
