Abstract
The Kandivalasa River Sub Basin near Cheepurupalli town of Vizianagaram district, Andhra Pradesh, India was monitored for groundwater levels at 41 observation wells during 2013–2015. Along with groundwater levels, the daily rainfall data is also collected for these years. A continuous decrease in groundwater levels was observed during the study period more particularly in the year 2015 which also had minimum rainfall. Groundwater depletion is observed mostly in the Eastern and South Western part of the basin where pumping wells are more. Groundwater balance studies have indicated that 11.3 MCM of groundwater can be utilized in the basin annually. However, the net annual groundwater draft has been found to be 16.6 MCM. Hence, over abstraction of 5.66 MCM is the main cause for depletion of groundwater levels. The water conservation and groundwater recharge measures have to be taken up at Chinnanadipally and Dummeda villages in the basin to have sustainable groundwater utilization in the basin.
