Abstract

In order to evaluate the effect of dry-wet treatment on well developed tidal flats along the complexcoastal line in the western part of Korean Peninsula, we adopted a finite element tidal hydrodynamic simulationmodel, ADCIRC incorporating newly suggested dry-wet option and aplied it to Chonbuk coastal area andKeum river estuary. Model comparison with observed current data by RMS error in the Chonbuk area showsvery good agrement within 1cm/sec of tidal velocity diference and 3% of error to maximum tidal currents.However there is not seen any significant advantages in dry-wet treatment. For the tidal volume tests in the Keumriver estuary, the differences are satisfied within 5% nevertheles of dry-wet treatment but in a near cros sectionit marks over 20%. However both results are almost same in tidal residual tests. Thus it can be concluded thatdry-wet option is not always necesary in the simulation of long-term dispersion analysis.
