Abstract:
The presence of suspended sediments (SS) along the coast and estuaries
are mainly derived from river flow, tidal currents and ocean waves. In large
quantities, the SS can alter the ecosystem of the area by limiting the level of
light penetration into the deeper seabed. Recently, a number of algorithms
have been developed to distinguish SS influenced area and clear water
regions in coastal water areas but these algorithms require complicated
computational analyses. Thus, a simple method is needed to accurately
detect the presence of SS temporally and spatially needs to be developed.
This study was conducted to detect the region that affected by SS along
coastal line and estuaries by using remote sensing technique. In order to
detect the region that affected by the SS on a daily basis, a simple algorithm
that based on empirical technique was developed. The algorithm is based on
the difference in the slope of the line connecting the wavelength of 0.47 µm
to 1.24 µm and the line connecting 0.47 µm to 0.66 µm.
