The present study on geochemical evolution of groundwater is taken up to assess the controlling processes of water chemistry in the Western Delta region of the River
Godavari (Andhra Pradesh), which is one of the major rice producing centers in India. The study region is underlain by coarse sand with black clay (buried channels), black silty clay of recent origin (floodplain) and gray/white fine sand of modern beach sediment of marine source (coastal zone), including brown silty clay with fine sand (paleo-beach .ridges). Groundwater is mostly brackish and very hard

This paper looks at the crucial issue of dry-season groundwater-availability in the state of Maharashtra, India. We look at the two key hydro-climatological measurements which are used to implement groundwater policy in the state, viz., water levels in 5000+ observation wells across the state and aggregate rainfall data. We see that there is substantial variation in groundwater levels within and across the years in most wells. We argue that for a large number of these observation well locations, aggregate

The optimal management of water resources requires that the collected hydrogeological, meteorological, and spatial data be simulated and analyzed with appropriate models. In this study, a catchment-scale distributed hydrological modeling approach is applied to simulate water stress for the years 2000 and 2050 in a data scarce Pra Basin, Ghana.

Urbanization likely to impact ground water quality and quantity leading to higher uncertainty and difficulties in management of pollution. Results yielding a good indication but the scenario demands continuous surveillance of waste water disposal from unauthorized discharges from small scale industries in Balanagar, Jeedimetla and Sanathnagar industrial development areas into the Kukatpally nala. It impacts very much on the Hussainsagar lake water. The groundwater flow model has computed groundwater balance for the entire catchment area of Hussainsagar.

Groundwater (GW) vulnerability is foundation stone for evaluating the risk of GW contamination and developing management options to preserve the quality of GW. The concept of GW vulnerability is based on the assumption that the physical environment may provide some degree of protection for GW against human activities as well as natural contamination. The main objective of this study is to find out the GW vulnerable zones in Burhner watershed using DRASTIC model in a geographical information system environment.
