Abstract:
Groundwater plays a major role in meeting the demands for water for various sectors in India. Over exploitation of groundwater is emerging as a serious problem in the country. Hence, detection of trends in groundwater levels is incredibly important for management of groundwater resources. In view of the importance of groundwater, the present study was undertaken in the 24 observation wells of the Dharwad district of Karnataka. To detect the trends in groundwater level, the techniques of the Mann-Kendall trend test and Sen’s slope estimator test were employed, and the results revealed that both significant increasing and decreasing trends were obtained. These increasing trends were more prevalent in the study area. The most significant positive slope occurred at W15 in the month of April, and the most significant negative slope occurred at W17 in the month of November.
