“…Application of geophysical parameters such as electrical resistivity with geological perception was utilised to resolve the hydrogeological complexity of the near surface (Sonkamble et al, 2013). Geophysical investigations such as electrical resistivity tomography (ERT) were carried out to delineate the subsurface lithological layers and saturated thickness.…”

“…Rajaveni et al (2014) explained how to assess the water levels in relation to dykes, drainage, lineament and weathered zone thickness. The utility of geophysical investigation to understood the hydrogeological complexities in granitic terrains in Telangana state has been described by Sonkamble et al (2014). In an interesting study, Yogeswar et al (2012) investigated the impact of sewage irrigation and groundwater contamination around Roorkee region in upper Ganga plain using advanced geophysical technique like direct current resistivity and radio magnetotelluric methods.…”

The hydrogeological setup of India represents a wide variation, from rugged Himalayan mountainous region in the north, extensive Indo-Ganga-Brahmaputra floodplain and deltaic region in the central and eastern part, aeolian-alluvial deposits in the west, vast basalt flows in the west central part, gently undulating central and southern region underlain by Precambrian crystalline, sedimentary and metamorphic, coastal deposits along the east coast etc.The research on hydrogeology has got special socioeconomic significance because India is now the largest extractor of groundwater in the world. The impact of overexploitation of the resource is surfacing in large parts of the country, in the form of lowering of water level, dwindling yield of well and deterioration in water quality.In recent years, extensive studies have been carried out in this field of geoscience. We have discussed these in different segments, after enumerating the broad hydrological framework of India. The segments are 1. Hydrogeological investigations in Indo-Ganga-Brahmaputra Plains holding one of the potential aquifer systems 2. Groundwater chemistry and contamination issues in Peninsular India 3. Urban hydrogeology 4. Groundwater modeling 5. Ground water exploration 6. Groundwater recharge and associated quality issues 7. Remote sensing and GIS applications 8. Coastal aquifers and 9. Groundwater management.It is observed that the potential groundwater reserve in the Indo-Gangetic basin and the Peninsular part of India has two serious issues: 1. Overexploitation of groundwater mainly in the western and north western parts and also in southern peninsular India in pockets and 2. Groundwater quality deterioration by anomalous concentration of arsenic, fluoride and salinity. The findings of the research will help in understanding the hydrogeological complexities in its entire gamut and also offers insight into the ways for sustainable management of groundwater resource of the country.

“…However, a regional scale studies using GRACE satellite data together with hydrological model have reported a huge loss of groundwater resources in northern India (Tiwari et al 2009). In peninsular India (Southern India), the semi-arid climatic conditions (Fishman 2018), granitic hard rocks aquifer (Sishodia et al 2016, Maréchal et al 2018, and channelized recharge sites and aquifer compartmentalization (Nicolas et al 2019) have prompted to opt groundwater as the only source of irrigation resulting expansions of groundwater critical zones (Sonkamble et al 2014). Sugarcane is one of the major cash crop of the country and occupy 3% of the total cultivated area in India.…”

India is second largest sugarcane producing nation with water foot prints ~ 104 BCM/year of which 80% met from groundwater of deep-wells. The large-scale groundwater management practices were found mostly untenable affecting the sugarcane agrarian and associated sectors. We developed a cell-level (2km x 2km) decision support tool (DST) employing the integrated hydro-geophysical investigations in sugarcane agro-watershed (399 sq.km) beset over granitic aquifer systems of Tattihalla River watershed, Southern India. The refined hydrogeological conceptual model derived from electrical resistivity tomography (ERT) and groundwater level (head) has been accounted into the numerical modelling. The model was run on transient mode for four stress periods during 2015–2017 and validated with calculated and observed heads. The normalized RMS error 7.57% of the validated model conveys its robustness and estimates groundwater budget at the demarcated 77 cells. The theoretical scenarios for water level projections against the increased groundwater pumping rates of 10%, 25% and 50% were generated. It showed declining trend of water level for projected 10 years period with varied magnitude and vulnerability for drought conditions. The different time periods of water level touching the basement (i.e. dry borewell), infers a distinct hydrogeological property of an individual cell advocating to adapt a cell level management plan. In this article, we explained two cells (Nos. 12 & 60) in detail to show the varying characteristic of aquifer against the different pumping rates.
