Abstract: Ground water is the most important resource in the region where it meets with water shortage. Climate change and shifts in precipitation intensity will affect groundwater continuity, thus altering groundwater level. In the present study groundwater level, rainfall and geochemistry of groundwater data have been collected for six years from 2011–2016. The deeper water level is noted in sedimentary terrain and the shallow water level is noted in hard rock regions. The higher intensity of rainfall is observed in the year of 2015 and the higher electrical conductivity is noted in 2013. The results illustrate the importance of precipitation intensity in relation to groundwater level and provide further insights for groundwater management in non–renewable groundwater systems and in a changing climate.
