Quantitative estimation of groundwater potentiality and rainfall infiltration in a typical crystalline environment

A sophisticated method of measuring water levels is adopted to determine the groundwater potentialities in a typical weathered and fractured environment by storage method. The frequency of the rainfall has shown a direct bearing on recharging the groundwater system compared to the intensity of the rainfall. The Thiessen polygon method is used to determine the weighted average of the rainfall over the basin area to estimate the ground water infiltration rates. The long term average infiltration to the medium is established as 15% of the total rainfall.
