Numerical Modeling Technique for Tracking of Disposed Dredged Material in Offshore Area

Abstract

The investigation in the present study for numerical simulation of the bed load movement and dispersion of the open water disposal of dredged material compares the results of the Radio Active Tracer (RAT) experiment near New Mangalore Port with the simulation of the same using MIKE-21 software module namely HD (Hydrodynamic) and MT (Mud Transport). In the modeling technique adopted the model input parameters have been modified to uniquely capture the dispersion of the dumped sediments and the results compare well with the in-situ RAT experiments. The present outcome of the modeling exercise is limited only to the dispersion pattern of the sediments vis-à-vis RAT experiment and thus is more qualitative and needs further studies for quantitative comparison.
