Abstract Variations of optical properties of sea water are due to the presence of dissolved and suspended materials with different absorption and scattering characteristics. Satellite based observations have been found to provide valuable inferences about the sediment levels of oceanic waters. The West coast of India is highly prone to erosion especially during the monsoon season due to the wave action associated with the south westerly currents. The heavy run-off from west flowing rivers in the peninsular region also contribute to the high level sedimentation in the offshore regions. In the present study, the multidate data from Indian Remote Sensing Satellite, IRS-1A has been utilised to analyse the sedimentation levels and dispersal patterns for the coastal region of Mangalore in Southern India. Digital techniques have been employed to bring out the variations in the sedimentation patterns (upto 14 levels) for the pre and post- monsoon seasons. The available insitu observations on wind, waves and tides have been used to understand the seasonal dispersal characteristics. The study has indicated high level of sedimentation in the post-monsoon period, revealing highly erosion prone nature of the coast. A semi- quantification of the sedimentation has also been attempted through correlation with sea truth data.
