COASTAL SEDIMENT DYNAMICS AND TRACING METAL POLLUTION

The properties of sediment particles, transportation and their deposition in the sedimentary environments can be deciphered by the granumlometric studies, which also provide critical information regarding sedimentary provenance and depositional conditions. Many factors like currents and wave activities, offshore and onshore movements, transgression and regression of the sea levels, periodic storms, confluence of streams, rivulets and rivers into the oceans can influence the grain size in the depositional environments. Variations in the size of the grains reflect various earth surface processes viz., developmental processes of landforms. So, many researchers from all over the world carried out panoptic research and emphasized the significance of granulometric analysis to understand and to distinguish various depositional environments viz., estuarine, lacustrine, fluvial and marine etc., in particular in the coastal realms
