    Scientific studies of estuaries have assumed a greater importance due to more than one reason. In the viewpoint of geologist, though most estuaries are epimeral, nevertheless are effective transporting agents for the terrigenous sediments in to the adjacent sea. Geo chemists consider that the chemical nature of the adjacent sea including the concentration of certain important trace elements and their equilibrium are to a great extent controlled by the estuary. In fact it is the biologists who have long before recognised estuaries as a pathway for anadromous and catadromous varieties of fishes. They have also known the estuaries as nursery grounds for various commercially important fin fishes and shellfishes. Coastal oceanographers and harbour engineers have recognised not only the impact of the estuaries in the coastal processes of erosion and sedimentation but also, the environments which preserve and provide various living and non-living resources.
