The Neogene/Quaternary boundary is reported to be erosional. The Pleistocene miliolite limestone shows the development of a sequence of palaeo-beach-dune complexes with the gradual fall of sea level. The late Pleistocene-Holocene stratigraphic units comprise different generations of deltaic sediments aggrading older tidal marshes and backswarnps. The late Holocene sea-level fall helped in delta progradation and the development of different accretionary units all along the coast.

The Dhund, an ephemeral river along its subsidiary drainage system forms a N-S elongated river basin in the Semi-Desert terrain of Jaipur District. The groundwater occurring in the aquifer zones of granite gneisses quartzites and alluvial formations is dwindling due to excessive mining of groundwater during the last one decide.In spite of high rainfall from 1989 to 1996 the declining trend of water levels are not reversed in major part of the area The falling water table can only be checked by proper groundwater management.

A buried channel has been located, in the basaltic terrain, near village Shenoli, District Satara, Maharashtra. It is composed of a gritty mass formed of a semi-consolidated material. The resistivity value of the semi-consolidated formation is 6.30 Ohm - m whereas the resistivity values of the vesicular basalts range between 18 and 32 Ohm-m. The specific capacity, unit area specific capacity, specific capacity index, transmissivity and hydraulic conductivity, with respect of the buried channel, are 609.07 LPM/m of drawdown, 12.12 LPM/m3, 95.47 LPM/m2, 353.26 m2/day and 55.37 m/day, respectively whereas the values of these parameters for basalt aquifers range from 67 to 117 LPM/m of drawdown, 0.7 to 4.27 LPM/ m3, 14.08 to 31.04 LPM/m2, 33.5 to 73.71 m2/day and 9.44 to 18.32 m/day, respectively. A comparison of the well characteristics and aquifer parameters reveal that the buried channel with semi-consolidated formation has distinctly better groundwater yielding properties.
The groundwater from the semi-consolidated formation has distinctly different quality. The electrical conductivity (EC) of the water from the basalt aquifers ranges between 417 and 555 micro mhos/cm with a modal value of 430 micro mhos/cm, which is 960 micro mhos/cm at 25° C for the semi-consolidated material forming the buried channel. The plots on the Trilinear diagram show that all the samples fall in field 5 where alkaline earths exceed alkalies and weak acids exceed strong acids but it is clear that the proportion of alkalies and weak acids in the water from the buried channel aquifer is higher than the water from the basalt aquifers.
