Abstract
The hydraulic analysis to obtain source strength of the dredge-induced suspended sediment was conducted by using the field data measured at Gunsan and Busan-Jinhe port dredging sites. Applying Kuo & Hayes' (1991) analytical method, the suspended sediment concentration and ambient flow velocity measured along plume axis were used to obtain the hydraulic parameters of turbidity plume dispersion. The analytical solution was compared with the various field measurements including the data sets of the U.S.Army Corps of Engineer. The results were generally in a good agreement with field data in the SS concentration distributions at the dredging sites. The source strength of suspended sediment for each site was calculated using plume parameters. The result shows that the source strength was increased with the proportion to the in situ-ambient flow velocity, but was less dependent on the particle size of dredged sediment.
