Description Satellite remote sensing data pertaining to two areas, one each on east and west coasts of India has been utilized to study suspended sediment dynamics within the near-shore region. For this purpose, thematic mapper image and second principal component image were used for area 'A' and 'B' respectively. The behaviour of sediment laden plumes was examined in detail to understand the distribution and dispersion of suspended sediments. Based on tonal and textural variation, five distinct types of turbid water masses have been identified in area 'A' and four in area 'B'. It is concluded that: (1) the currents of the study areas are influenced mainly by riverine discharge and shoreline configuration, (2) littoral sediments are transported in southwest direction in area 'A' and in southeast direction in area 'B', and (3) qualitative estimates of suspended sediments and their movements can be well studied with the help of satellite remote sensing technology. Thus, the present study demonstrates the capability of remote sensing technology in determining littoral sediment dynamics correctly, economically, less laboriously and in a short time
