Abstract
EFDC model was applied to reproduce velocity fields and to evaluate the dispersion characteristics of suspended sediments (SS) around a Daesan port. Numerical results using two-dimensional hydrodynamic model of EFDC showed good agreements through comparison with the time series and harmonic analysis of the tidal elevations. The dispersion patterns of the suspended sediments using the calculated velocity fields were calculated to move from east to northeast direction in flood tide and from west to southwest in ebb tide for dredging of sea route, respectively. Also, the suspended sediments were widely dispersed into the front areas of a Daesan port, Nanji-do and Garorim bay in the long-term. Therefore, it was inferred that the environmental problems for sea pollution would be occurred seriously if the dredging for sea route would be continued in the long-term.
