Crescentic coastal belt of Odisha, stretching about 480kms long from Digha, Balasore to Chilika and 10 to 15 kms. broad occupies the cutfall regions of major rivers like the Mahanadi , Brahmani, Baitarani, Subarnarekha. The belt is underlain by a thick pile of unconsolidated sediments of Miocen to recent age. Alternations of sand and clay beds, of various shades, grades and texture comprise the sediments, horizons, often attaining individual thickness of over twenty-five meters, from the principal aquifers. Tube well tapping 35 to 65 meters of aquifer yield 140 to 270M3 per hour, for drawdowns varying from 3 to 13 meters. Both the fresh and saline ground water co-exist in the system, often interchanging their position. This paper spalls out the hydro-geological framework , delineates the regional disposition of fresh and saline ground water bodies , recommends special techniques of production wall constructions , stressed the need for scientific management of fresh ground water resources and rigorous monitoring to safeguard against salt water contamination.
