Quaternary alluvium - Sediments in the shallow depths (0 to ~15 m bgl) represent Quaternary alluvium, which are good aquifers with transmissivity of the order 300 m 2 ·d −1 (Raghava Rao et al., 1976). A stratigraphic section delineating different aquifers and uncertainties is prepared based on the above inferences and shown in Fig. 7 .
