The Responses of a Hydrodynamic Model to Different Open Boundary Conditions in the Northern Gulf of Thailand

Abstract


The Princeton Ocean Model (POM) was applied to simulate water circulation in the Northern Gulf of Thailand (NGoT) under different open boundary conditions including the elevation forcing condition (Case B1) and the current forcing condition (Case B2). Monthly mean wind, tide, river discharge, water temperature and salinity and bottom topography were used as major forcing in the experiments. Monthly depth averaged currents between two cases were compared to investigate the simulation performances. Case B1 resulted in strong current greater than 100 cm/s that did not seasonally change near the open boundary. However circulation weaker than 10 cm/s was generated in the area farther from the open boundary, such as the upper Gulf of Thailand, where wind played an important role to water circulation. Case B2 generated weaker current, compared with Case B1 near the open boundary, and wind seemed to control the residual circulation. The results also revealed no significant difference between the current patterns of both cases in the upper Gulf of Thailand located farther in the north of the open boundary. The model calibrations with measured tidal data showed better results of Case B2 than those of Case B1 in simulating water circulations in this area.
