Abstract

The Ganga River Basin of India is an active foreland basin having an east–west elongated shape. The basin has been formed in response to the uplift of the Himalayas after the collision of Indian and Asian plates. The Ganga Basin forms one of the largest underground reservoirs in the world and came into existence as the result of sedimentation in the foredeep in front of the Himalayas. The sedimentation period belongs to the upper tertiary period and it continued all through the Pleistocene up to the present time. The various geophysical and exploratory-drilling investigations have indicated that the depth of the alluvial is variable from about 1000 m to over 2000 m and encompasses a number of aquifer zones, both fresh and saline. On the basis of various studies, depth to basement rock is shown in Figure 2.1.
