“…Tides are semidiurnal with a mean tidal range of 6.5 m (spring tide ¼ approximately 8 m, neap tide ¼ approximately 4 m) with 25 instances of higher high water and lower high water, annually . The surface sedimentary facies are primarily mud flats in the eastern part of the tidal flat, sand flats in the western part, and mixed flats in the area between them (Woo and Je, 2002). Precipitation is concentrated nearby; 70% of the annual total during the rainy summer months from July to September occurs near the salt marsh .…”

This study presents results of assessment of X-band SAR image for mapping salt marsh. Multi-temporal TerraSAR-X data were acquired with different incidence angle (23°, 31°, and 39°) in mono-and dual polarization modes (HH, VH/VV) for backscattering analysis. Backscattering coefficients from industrial areas were used to confirm the calibration. The types of land cover were differentiated based on seasonally averaged backscattering coefficients of classes. The behavior of backscattering coefficients was also analyzed as a function of SAVI (soil adjusted vegetation index). Decision trees were used to build classification rule sets. Accuracy of classification was estimated by reference image generated from field works and ancillary data.

“…The tidal range at Incheon, in the middle of the west coast, is approximately 7.3 m, whereas that at Mokpo, in the southern part of the coast, is approximately 3 m. Vast tidal flats have developed because of this large tidal range. These tidal flats are of various types, including semi-closed tidal flats, such as at Gomso Bay, and open tidal flats, such as at Ganghwa-do (Woo and Je, 2002). Tidal channels, which are distributed within a tidal flat surface, are conduits for water, sediments, nutrients, detritus, and aquatic organisms and thus link the nearshore marine environment to highly productive tidal marshes (Simenstad, 1983;Odum, 1984;Rozas et al, 1988;Pethick, 1992;French and Spencer, 1993).…”

“…This study area is supplied with substantial amounts of sediment from the Han River and includes a variety of environments due to influences of the mainstream and a tributary of the Han River. The tides are semidiurnal with a mean tidal range of 6.5 m (spring tide = 8 m, neap tide = 4 m) (Woo and Je, 2002). The sedimentary facies are comprised mainly of mud flats on the eastern part of the tidal flat, sand flats near the western part, and mixed flats in the wide area in between.…”
