  abstract = {{S}ince the 1990s, {I}ndian farmers, supported by the government, have partially shifted from surface-water to groundwater irrigation in response to the uncertainty in surface-water availability. {W}ater-management authorities only slowly began to consider sustainable use of groundwater resources as a prime concern. {N}ow, a reliable integration of groundwater resources for water-allocation planning is needed to prevent aquifer overexploitation. {W}ithin the 11,000-km(2) {M}usi {R}iver sub-basin ({S}outh {I}ndia), human interventions have dramatically impacted the hard-rock aquifers, with a water-table drop of 0.18 m/a over the period 1989-2004. {A} fully distributed numerical groundwater model was successfully implemented at catchment scale. {T}he model allowed two distinct conceptualizations of groundwater availability to be quantified: one that was linked to easily quantified fluxes, and one that was more expressive of long-term sustainability by taking account of all sources and sinks. {S}imulations showed that the latter implied 13 % less available groundwater for exploitation than did the former. {I}n turn, this has major implications for the existing water-allocation modelling framework used to guide decision makers and water-resources managers worldwide.},
