Two- and three-dimensional models were applied to simulate hydrodynamic circulation patterns in the Irish Sea. There are two main features in the region: a relatively deep and narrow North Channel, and a wider and shallower St. George's Channel. The main force governing circulation in the region is the semi-diurnal tide; summer solar heating is also important. The model domain was divided into 65,000 squares each having 2 km sides to perform hydrodynamic calculations in 3 dimensions; a 1 km rectangular grid was also used for hydrodynamic calculations in 2 dimensions.Extensive simulations for calibration of the hydrodynamic model were carried out for different types of boundary conditions and diversities of roughness coefficients. Models were calibrated accordingly to available data, which include current velocities at 14 locations and tidal elevations at 15 locations along the Irish and British coasts. Comparison between individual models runs were made and results were related to field data indicating that models represent circulation pattern reasonably well.
