| Abstract: | Multiscale and long-term work is needed to tackle the scientific challenges found
in areas vulnerable to climate change and anthropic pressure. This is the case in the
semiarid and drought-prone regions of southern India where freshwater is scarce
and agriculture near fast-growing cities is triggering high water demand. The Indo-
French Center for Groundwater Research (IFCGR) was established in 1999 between
the Indian National Geophysical Research Institute (NGRI) and the French Geological
Survey (BRGM) at the NGRI campus in Hyderabad, India. For almost 20 yr, the
IFCGR has studied the hydrodynamic properties and associated hydrological processes
in crystalline aquifers. To that end, the Center set up two sites for observing
groundwater in crystalline rock aquifers: (i) the Maheshwaram basin for the study of
groundwater management at catchment scale, and (ii) the Choutuppal experimental
site for the detailed study of hydrogeological processes at local scale (between
wells). Multiscale approaches allow the characterization of hydrodynamic and transport
properties of the shallow weathered part of such crystalline aquifers and the
implications for groundwater management under overexploitation conditions. The
objective is to provide suitable characterization of aquifer properties for developing
modeling and management tools applicable to such heterogeneous aquifers. |
