The Impacts of Confined Disposal Facilities on Calcasieu Ship Channel Sedimentation

The confined disposal facilities (CDFs) are the areas along Calcasieu Ship Channel to store dredged sediments from the ship channel. As the sediments settle in the CDFs, the low concentration sediment flows are discharged into the open water adjacent to the CDFs. The paper demonstrates flow and sediment transport characteristics in the open water due to the CDF discharge. The sediment distributions in all three dimensions in the water are revealed. The lake current effects were also investigated. A commercial CFD package ANSYS-FLUENT is used to simulate all cases in this study.
