Abstract
- Sediment resuspension during dredging operation for maintenance, remediation of contaminated sediment or excavation of marine aggregate from the bottom sediment and subsequent movement of the resuspended sediment plume to the outside of the project area in river and sea are of great interest for the protection of aquatic environment. In order to monitor development and spreading of sediment plume, a potentially affected area should be observed simultaneously as often as possible. For this purpose, the remote sensing imagery has been successfully used in many countries as satellite sensors meet the above mentioned requirements. The most widely used remote sensing imagery is from Moderate Resolution Imaging Spectroradiometer (MODIS) band 1 (620-670nm) reflectance data with spatial resolution of 250nm. When monitoring dredging plumes, images from Landsat satellites having a repeat capture of every 16 days are used to assist the interpretation of MODIS images. A few Korean examples are shown here for future reference for Geostationary Ocean Color Imager (GOCI) uses from marine aggregate mining area. project area in river and sea are of great interest for the protection of aquatic environment.
