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.

Abstract


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.
