Abstract
A silt curtain is commonly used in a reclamation work to reduce outflow of turbidity from construction area. However it's quite difficult to get an appropreate drawing plan of the curtain since there is little information about a series of real phenomena which occurs under the sea, with the exception of some laboratory experiments with small scale in which we can't remove scale effect. In this study, we carried out two-dimensional numerical simulation with a scale of the construction site using the two-fluid model with the k-e turbulence model to investigate turbidity transport generated by direct dumping of soil using a hopper barge with bottom doors. We briefly discussed characteristics of turbidity transport and effectiveness of the silt curtain.
