Abstract Precious groundwater is the backbone for modern human civilization. Availability or scarcity of groundwater has direct bearing upon environment. Groundwater level fluctuation is a natural phenomenon on seasonal basis influenced by multiple factors like amount and intensity of rainfall, temperature and rate of evapotranspiration throughout the year. Studies on different aspects of groundwater are gaining academic momentum day by day. The present study is conducted for Lower reaches of the Ranganadi river basin where focus is given to observe pattern of temporal (seasonal) fluctuations in groundwater level in different geomorphic units, i.e., upper piedmont, lower piedmont and alluvial plain covering 37 villages. In the upper piedmont zone the groundwater level at fell below the ground surface maximum of 7.35 m during 2020-2021 lean period. In Lower Piedmont Zone, groundwater level is observed at a depth of around 2.0 m during lean period while during peak period it is around less than 1.0 m. Similarly, in alluvial plain groundwater level during lean period is around at a depth of below 2.0 m during lean period, on the other hand it is at a depth of less than 1.0 m. The region can be identified as non-deficient in groundwater both in lean and peak periods. The only fact is that groundwater level moves down to a considerable extent during lean periods in all of the respective geomorphic units.
Keywords Groundwater level fluctuation, Upper piedmont, Lower piedmont and Alluvial plain.
