Determination of an optimal interpolation technique to represent the spatial distribution of groundwater quality at urban and peri-urban areas of Proddatur, Y.S.R district, Andhra Pradesh, India
Ground water quality Geostatistics Multivariate analysis
2014/11/17
The preliminary aim of the present study is to analyze the spatial variability of ground water
quality parameters in Proddatur, India. The spatial variability and the GIS maps can be used
for mana...

Determination of Aquifer Diffusivity from Annual Fluctuations of Ground Water Levels
Aquifer Diffusivity Annual Fluctuations Ground Water Levels
2009/10/29
Annual fluctuations of ground water levels of an aquifer are described as a
consequence of water recharging periodically over a part of the aquifer. These
areas can be depicted by drawing maps showi...
