The TIDE, nonlinear finite element model for the simulation of tidal analysis in a shal- low ooastal area was tested for its applicability at the Saemankeum day. Calibration of the TIDE model has been carried out using the six observed field data collected at five locations within the region for tidal velocity. Verification tests have been done using the six observed field data and four data o- tained from the hydraulic model test for the tidal velocity and elevation. Since the simula- tion results for the tidal elevation at Kunsan outer port by the TIDE model are well agreed with the results from the tidal table for one month, it is proved that the TIDE model may be used effectively to predict the tidal movement in the Saemankeum bay for a longer period.
