<p><span style="font-size:14px"><span style="font-family:Arial,Helvetica,sans-serif">In the present study, groundwater level trends have been evaluated using the non-parametric methods i.e., Modified Mann-Kendall (MMK) and Sen&rsquo;s slope estimator during the period 1998 to 2012 at 13 locations in 4 districts of Lucknow division namely Hardoi, Laxmipur, Lucknow and Sitapur of Uttar Pradesh, India. The entire trend analysis has been verified at a significance level of 5 percent. The groundwater level trend analysis has shown negative values for 7 locations covering 54 percent area and positive values for 6 locations covering 46 percent area in pre-monsoon season. However, in post monsoon season, 4 locations covering 31 percent area exhibited negative and 9 locations covering 69 percent area revealed positive trends. The difference in the water level trends in two different seasons may be attributed to the recharge by rainfall in post-monsoon season.</span></span></p>
