연안개발공사로 인한 부유토사의 환경 악영향 저감방안 고찰

Abstract

Coastal development works generally increase the suspended sediment concentration of the ambient water, which consequently cause environmental impacts in various manners. The most active measures in three sides have been reviewed with a special consideration of their applicabilities in Korea. Referring to the cases of the USA, the legislation of environmental windows seems to be not proper for environmentally sound and sustainable developments (ESSD) until sufficient scientific data are obtained to address the individual issues of potential negative impacts. Feedback monitoring can be regarded as the best way for ESSD. Korea has the basic legal system for the feedback monitoring as well as environmental impact assessments (EIA). However, it is strongly required that the frequency, period and parameter for the related surveys should be improved for the true ESSD. Additionally, environmental facilities such as environmental dredgers should be widely used for the mitigation.
