Case studies on rainwater harvesting and artificial recharge – A compilation by Central Ground Water Board
Posted on 17 May, 2011 09:13 PM
Groundwater caters to the demand of ever growing domestic, agricultural and industrial sector of the country and is being indiscriminately exploited by several users. On the other hand, rapid urbanization and land use changes has resulted in reduced natural infiltration or recharge of aquifers.
This has led to various problems related to quantity and quality and issues like the decline in water levels, depletion of groundwater resource and quality deterioration. There is thus an imperative need for augmenting the valuable groundwater resource. Artificial recharge and roof top rainwater harvesting is one such method that can revive this precious resource. Several traditional and scientifically proven artificial recharge and rainwater harvesting techniques have been adopted in different parts of the country. These structures have proven to be viable option for augmenting the groundwater aquifers by making use of surplus surface runoff.
Groundwater management in Andhra Pradesh - Time to address real issues – A report by Institute for Resource Analysis and Policy
Posted on 17 May, 2011 02:16 PMWith 49 per cent of the total irrigation from groundwater, the state of Andhra Pradesh accounts for 5.3 per cent of the net groundwater irrigated area in the country.
Groundwater scenario in major cities of India – A report by Central Ground Water Board
Posted on 17 May, 2011 10:35 AM
It covers varying groundwater scenarios in the country including the highly developed metros, the hilly region, the coastal cities, the cities tapping unconsolidated and hard rock aquifers. The report briefly describes the administrative set up, status of water supply and demand, groundwater scenario, feasibility of rainwater harvesting and groundwater development strategy.
It is an updated version of an earlier report on “Groundwater in urban environment in India” (2000). Since then, groundwater regime, urban demography and water demand have changed enormously. This report will form a scientific base for an in-depth understanding of urban groundwater system including aquifer geometry, water level behavior and groundwater quality. The possibility of artificial recharge to rejuvenate the urban aquifers has also been discussed.

Artificial groundwater recharge and recovery of a highly saline aquifer – A paper in Current Science
Posted on 25 Apr, 2011 07:59 AMA key factor in the long-term viability of aquifer storage and recovery is the extent of mineral interaction between two dissimilar water types, their recoverable fractions and consequent impact on water quality and aquifer stability.
Groundwater: From mystery to management - An article by TN Narasimhan
Posted on 22 Apr, 2011 12:07 PMGroundwater has been used for domestic and irrigation needs from time immemorial. It is a component of the hydrological cycle, vital for human sustenance. Unlike surface water, groundwater cannot be readily observed. Consequently, it was long considered to be mysterious or even occult in nature, influencing legal decisions relating to groundwater ownership and use.
Adapting to the global groundwater crisis - Its usage needs to be regulated and monitored
Posted on 22 Apr, 2011 12:03 PMThe global groundwater crisis centers on withdrawals notably exceeding short term renewable storage. The current global groundwater crisis reflects the fact that over the past century, groundwater withdrawal has grown to exceed natural renewable groundwater storage. The single most important cause is the deep well turbine pump. Groundwater depletion is very high in both the United States and India.
