This study concerns the development of a methodology using modern techniques of
data generation (Modeling) and interpretation (GIS) to compute groundwater plausibly at
regional scale, alternate to previously established norms. The approach is centered on quantitative estimation of two main parameters-input and output. GIS techniques along with soil
vegetation model (CropSyst) have been demonstrated for the calculation of groundwater
balance components. Using the developed methodology water resources of the Ludhiana
district for the period between, 2000 and 2010 were estimated. The temporal changes in water
balance components indicated that the major inputs to the hydrologic system are rainfall and
canal water and the major out component are evapotranspiration (ET). Multi-annual (2000 to
2010) average of 719 mm rainfall, 88 mm canal water, 74 mm of groundwater inflow, with
annual loss 974 mm as ET, caused 123 mm of net negative groundwater recharge in Ludhiana
district. The annual computed rise/fall with the developed methodology closely matched the
observed values.
