Aquifer Management

Deep wells and prudence - Towards pragmatic action for addressing groundwater overexploitation in India - A World Bank document (2010)

India is the largest user of groundwater resources in the world. It is estimated that approximately 230 cubic kilometers per year is used annually, this is more than a quarter of the total world consumption from this resource.

It is in this context that this World Bank report looks at the reasons for this quantum of groundwater usage.

The report delves into socio-economic and political reasons and looks at policies which inadvertently promote so much extraction. The report also analyses various attempts to manage this resource. These attempts range from government and international agency efforts directed to grassroots mobilisations. Finally the report comes out with suggestions to deal with this crisis.Read More

Groundwater management protocols and pilot experiences – A presentation by ACWADAM

This presentation by ACWADAM deals with introducing groundwater management protocols for wells in different phases of groundwater use. These protocols include geo-hydrology in watershed development, protection of recharge areas, efficient well use, pump capacity regulation, distance with respect to drinking water well regulation, depth regulation in drinking water well, regulation of agricultural water use and groundwater management through sharing.Read More

Community organisation in groundwater management – A presentation by ACWADAM

community organisationThis presentation by ACWADAM on community organization in groundwater management deals with the processes involved in people’s mobilization and participation. The requisites of groundwater management include: resource enhancement, demand management, equitable distribution, institutional mechanism and controlling of free riding. It deals with groundwater management at a local scale when compared to aquifer management.

Aquifer management involves:Read More

  • Identification of aquifer on the basis of geology;
  • Identification of recharge and discharge areas;
  • Assessment of aquifer capacity and yield through aquifer mapping;
  • Protection of recharge area and increasing the groundwater level through artificial recharge in recharge area (based on the geology);
  • Treating groundwater as a common property resource;
  • Encouraging community use of groundwater and restricting individual use;
  • Putting in place an institutional mechanism and legal back up for community groundwater management;
  • Awareness generation regarding groundwater and science of hydrogeology.

Status report of saltwater intrusion and groundwater management studies in coastal and deltaic regions – A research report by the National Institute of Hydrology

The report presents a literature review on the status of research related to saltwater intrusion and groundwater management in coastal and deltaic environments in the east coast of South India. The area is typically characterized by highly productive and alluvial aquifers and high use of both surface as well as groundwater. Seawater intrusion into the freshwater aquifers is extensive due to increased pumpages.

A quantitative understanding of the patterns of movement and mixing between freshwater and saline water and the factors that influence these processes is stressed in the report. It presents the mechanics of saltwater intrusion through studies by Ghyben and Herzberg and later on by Hubbert. A comprehensive review of studies by Reilly and Goodman relating to saltwater intrusion is discussed. Later advances in understanding saltwater-freshwater relationship through numerical models like sharp interface model and miscible flow model are described.Read More

Groundwater - Towards an aquifer management framework

This paper published in the Economic and Political Weekly dwells on the groundwater management debate and makes suggestions for developing a viable approach to sustainable and equitable management of groundwater in India. The article outlines an aquifer management approach towards utilisation of groundwater rsources, which are rapidly being depleted across the country. The paper argues that the recognition and understanding of the aquifer complexity is missing in the current methodology on assessment of groundwater potential and that we are not yet ready for an aquifer management approach.
