Abstract The long-term variation in flow velocity, temperature and salinity fields in the Ise-Mikawa Bay estuary was examined in a triennial simulation, using a timedependent 3-D hydrodynamic model. The simulation covered from April 1993 to March 1996. The daily change regimes of the observed sea-surface winds, tidal elevation at the open boundary, river discharges and meteorological parameters were incorporated into the forcing variables of the modelled estuary. Simulated distributions of temperature and salinity were compared favorably with the field measurements both in time and space,
