The availability, development and management of ground water plays a vital role in the sustainable development of coastal regions. The difference between the recharge and discharge from the aquifer decides the level of water table. Water table generally rises during the monsoon as the rainfall infiltrates into the subsurface ground and the water table is lowered during summer. Therefore, an attempt is made to study which includes water level fluctuation and evaluation of seasonal variation of ground water levels in watershed of Nagavali Vamsadhara basin.
