Abstract

Recognizing the importance of the marine sciences, an Oceanography and Survey of Off-shore Area Unit has been set up within the newly established National Aquatic Resources Agency (NARA) of Sri Lanka. Work programmes initiated by NARA include the investigation of the coastal regions of the island which would be integrated with the proposed hydrographic and oceanographic surveys to be undertaken in early 1984. The present study is confined to the Kelaniya – Negombo coastal zone and is the first phase of the survey. An account is given of the general coastal features and the geological resource potential of the area. Substantial amounts of ilmenite occur at several localities along the beach. At some points bulk samples of beach sands contain over 65 per cent of the mineral ilmentte. .4 low grade peat deposit is described which occurs in the silted up lagoon-the Muthurajawela swamp. The importance of the rational management of the Coastal zone is also discussed as coastal areas and the coastal environment are important resources for socio-economic development.
