| This study analyzed a hydrodynamic behavior using the EFDC model (Environmental Fluid Dynamics Code) in the downstream of the Nakdong River in the case of a storm surge and a localized torrential rainfall caused by a major typhoon, and the sea level rise caused by global warming. The study area is selected Gaduk island with the lower boundary and Jindong with the upper boundary, to investigate the total river hydrodynamic behavior including the estuary. In order to verify this numerical model, the calculated results was compared with the observed stage at each gauging point in case of the storm rainfall in 2003 and 2006. From the results, it was shown that the numerical model(EFDC) has high accuracy and is useful in simulating more various cases. |
