估算气候变化对地下水补给的影响将有助于为流域地下水开发和管理规划制定未来的计划。它也将有助于农业和其他资源规划。还可以判断所需的种植模式转变。研究对象为佘楚吉河流域，流域面积5646.98 km2。整个地区由17个流域组成。采用3种不同的方法评价了气候变化对降雨、径流和估算地下水补给的影响。通过水量平衡、Krishna Rao(1970)和地下水位变化，地下水补给量分别占降水的3.11% ~ 49.28%、0% ~ 15.34%和0.72% ~ 14.62%。气候变化的影响有利于显著增加17个流域中的6个流域的降雨量，而在该流域的17个流域中发现5个流域的径流量增加。流域上游北部和中游最南端的降水和径流受气候变化的影响。舍特兰吉河流域面积加权降雨量显著增加。 The areal mean depth of monsoon runoff for entire Shetrunji basin was increasing significantly at the rate of 17.7 mm per decade. The groundwater recharge assessed by water balance method was found higher as compared to Krishna Rao (1970) and water level fluctuation method. The groundwater recharge expected by water balance, Krishna Rao (1970) and water level fluctuation methods is found to be enlarged in 13, 9 and 6 watersheds out of 17 watershed of the basin. The areal mean depth of groundwater recharge in Shetrunji basin during monsoon season in water level fluctuation method was found increasing significantly at the rate of 13.01 mm per decade due to climate change impacts.
