Paper Abstract

In the Saemangeum coastal area as a study area, the tidal dyke of 33 km-long has been constructed for over 10 years. This large scale of coastal engineering work has influenced the environment around the Saemangeum tide embankment. Especially the construction has induced in the changes of ocean circulation system, so that the re-suspension and movement of the Suspended Sediments (SS) were changed. The Suspended Sediments Concentration (SSC) is an important factor for understanding of the Saemangeum oceanic environmental change because SSC directly affect to the primary production by phytoplankton in the ocean. Accordingly we investigated and monitored the SS and chlorophyll concentration change using time-series multi-sensor satellite data. We used Landsat TM/ETM+ for the SS and chlorophyll monitoring respectively. As a result, it was found that the northern sea area of Gogunsan Islands had significantly become clear after the completion of 4th embankment in the end of 2003 whereas the southern sea area was getting a high amount of incoming flux of SS through 2 dyke gates that were still under construction. Chlorophyll concentration around the 4th embankment showed an increasing pattern after dyke construction.
