Guidelines for successful well site selection – A paper in Current Science

Groundwater is a natural replenishable resource. It is an important source for various purposes, including drinking, irrigation and industrial, due to insufficient surface water supply and frequent failure of monsoon. Identification of groundwater zones depends upon many factors such as distribution of rainfall, runoff, grain size of soil, topographic features, type of landform, drainage conditions, lithological characteristics, land use practices, depth to groundwater level and environmental constraints, which are not uniform in any area.

Impact of the 2004 tsunami on the geology of Car Nicobar Island – A paper in Current Science

Car NicobarThis paper in Current Science deals with the impact of the 2004 tsunami on the geology of Car Nicobar Island. The historic tsunami of 2004 in the northern Indian Ocean severely affected the eastern coastal areas of peninsular India and Andaman-Nicobar Islands. The Andaman-Nicobar Islands experienced intense damage to the coastline, at places reaching several hundred metres deep into the island.

Groundwater and artificial recharge investigations around proposed site of the Devi Ratn Hotel, Ballupura, Jaipur, Rajasthan - A report by Green Systems

Green Systems has prepared this report on the possibilities of creating a system for the recharge of groundwater for the Devi Ratn Hotel in Jaipur, Rajasthan. The proposal is an in-depth study of the geo-morphological setup of the area; there are also findings on geology and hydrology and the area's climate and rainfall and groundwater resources.

The final proposal is based on these findings and consists of a series of diagrams that not only suggest the design of various recharge structures but also their placements around the hotel site.

Groundwater and artificial recharge investigations, at the site of the Devi Rasa Boutique Hotel in Amer, Rajasthan - A report by Green Systems

The document is a proposal for setting up of a groundwater recharge system for the Devi Rasa Boutique Hotel near Jaipur. The consultants,  Green Systems, have conducted an indepth study of various parameters which include hydro-geology and climatic conditions to come up with a set of proposals for the hotel. To come up with their suggestions the consultants also make use of technologies like remote sensing, GIS and Vertical Electrical Sounding (VES).

Earth sciences in watershed management – A presentation by ACWADAM

This presentation by ACWADAM on earth sciences in watershed management shows how the occurrence of water within a watershed is governed by the rock types occurring both at the surface and within the subsurface, their sequence and their structure. The presentation deals with the basic components involved in the mapping of a watershed –Read More

  • The type of rocks (lithology), and
  • The structure (whether these are folded, faulted, fractured, jointed etc.,)

Augmenting groundwater resources by artificial recharge: A case study of Kolwan valley by ACWADAM

The presentation by ACWADAM deals with a case study of augmenting groundwater resources by artificial recharge in Kolwan valley, Mulshi taluka, Pune. The DfID funded project was undertaken by the British Geological Survey in collaboration with its partners in India from 2002–2005. The objectives of the study were:Read More

  • Improved knowledge of the impacts of managed aquifer recharge in different physical and socio-economic settings.
  • Guidance on scope and effectiveness of managed aquifer recharge for implementers, funders and policy makers.
  • Dissemination of knowledge.

The living wisdom: Using local well driller knowledge to construct digital groundwater data bases – A report by CAREWATER

carewaterThe report by Carewater INREM Foundation draws inferences from studies across the Indo-Gangetic Basin on using local well driller knowledge to construct digital groundwater databases. The low density of current groundwater instrumentation networks in the region is both cost and management intensive, contrary to local knowledge, which has greater spatial coverage and can be obtained at a relatively lower cost. An efficient way to tap such local groundwater knowledge is through well drillers. Read More

Surface and groundwater quality studies in Ghataprabha representative basin - A research report by National Institute of Hydrology

The study analyses the surface and groundwater quality of Ghataprabha representative basin during pre-monsoon and post-monsoon seasons. It looks at the primary impact of land use and cropping pattern on water quality using physico-chemical analysis, geo-chemical classification of groundwater samples and monitoring of groundwater quality.

Streeter-Phelp’s model is applied to understand the variation of dissolved oxygen along the course of the river from a point source. The study attempts to understand the impact of irrigation return-flow and use of pesticides, fertilizers & manures on surface and groundwater quality. The literature review offered indicates a dearth of studies on the subject for hard rock catchments and puts forward the need to do basin-wide as against area-wide studies.Read More

Geology of India - DN Wadia - Macmillan publishers (1919)

Geology of India - Book CoverGeology is the science and study of the composition, structure, physical properties, dynamics and history of the liquid and solid materials/matter that constitutes the Earth, and the processes by which they are formed, moved or changed.

The Geology of India by DN Wadia, a geologist with the Geological Survey of India, is considered to be one of the most important and complete reference works available today on the subject.Read More

Total contents - 398 pages.

The book divides India into three main geological divisions - the triangular plateau of the peninsula, the mountainous or the extra-peninsular region bordering India on the west north and east, and the Indo-gangetic plain extending from the valley of the Indus to the valley of the Brahmaputra in Assam. The desert region of western Rajasthan is considered to be a unique fourth category, as it combines characteristics of two of the three main divisions.
