Actual Problems for Expanding Prediction of Spilled Water at Reclamation Using Cutter Suction Dredger

Abstract

Regulations controlling the quality of water discharged from reclaimed areas are becoming more and more strict for reclamation projects which use cutter suction dredgers. These regulations seek to prevent the damaging effects of spilled water on the coastline. For this reason, it is necessary to skillfully manage the growing estimates of water that is discharged along with fine soil particles. Reclamation projects which use cutter section dredgers dredge the sea bed, sucking up soil as well as water, and transport everything to the reclaimed area through a system of distribution pipes. These pipes are also connected to the project's outlet system for discharging water and fine soil particles. The conditions at reclaimed areas under construction change daily, and we must be able to precisely predict these changes. Although several methods have been proposed, one must be selected. This paperwill introduce the actual problems of density and the growing estimates of discharged water and fine soil particles.
