The effects of geological heterogeneities and piezometric fluctuations on groundwater flow and chemistry in a hard-rock aquifer, southern India

Perrin, J ; Ahmed, S ; Hunkeler, Daniel

In: Hydrogeology Journal, 2011, vol. 19, no. 6, p. 1189-1201

Crystalline aquifers of semi-arid southern India represent a vital water resource for farming communities. A field study is described that characterizes the hydro-dynamic functioning of intensively exploited crystalline aquifers at local scale based on detailed well monitoring during one hydrological year. The main results show large water-table fluctuations caused by monsoon recharge and...
