ABSTRACT

The study investigates the problems of silt protector used for mitigation measure ofsuspended sediments (SS) during coastal construction and provides their improvements basedon the field investigation and analysis of the environmental impact assessment reports for thecoastal development projects of Korea. The field investigation along west, east and south coastsof Korea reveals a variety of problems in the installation and management of silt protectorsolely used for the SS mitigation in Korea. Major problems include installation itself, low costand quality of silt protector, and maintenance. These problems superimpose the effectiveness ofsilt protector in mitigating coastal environment impact. The present study provides the specificguideline on the project type needed for the installation of silt protector, installation standardand planning, maintenance and management. The study also suggests new mitigation optionssuch as environmental window to limit the construction period and environmental dredger tocompensate for the deficits of silt protector.
