India’s groundwater typologies – A presentation by ACWADAM
Posted on 22 Sep, 2010 08:01 AMThis presentation by ACWADAM deals with groundwater typologies in India. The typology of groundwater can be defined in many ways based on a) Uses of Groundwater, b) Geography, c) Geology, d) Hydrogeology (Aquifers), e) Groundwater Quality, f) Stage of Groundwater Development, and g) Socio-ecology of Groundwater.
Groundwater management: Conceptual framework – A presentation by ACWADAM
Posted on 20 Sep, 2010 08:36 PMThis presentation by ACWADAM deals with the conceptual framework of groundwater management.
Groundwater management under the climate change scenario in India – A presentation by ACWADAM
Posted on 20 Sep, 2010 08:17 AMThis presentation by ACWADAM deals with the issue of groundwater management under the climate change scenario in India. Climate change is a change in the statistical distribution of weather over periods of time that range from decades to millions of years. The causes are -variations in solar radiations, plate tectonics, volcanism and change in earths orbit & axis.
Hydrologic properties of rocks – A presentation by ACWADAM
Posted on 19 Sep, 2010 06:22 PMThis presentation by ACWADAM deals with hydrologic properties of the rock framework in which groundwater occurs and through which it moves. In watershed programmes, it is necessary to develop a correct understanding of the storage and transmission of water within such channels because the shape of openings in a rock or sediment, their size, volume and interconnection play a vital part in the hydraulic characteristics of an aquifer.
Groundwater management protocols and pilot experiences – A presentation by ACWADAM
Posted on 19 Sep, 2010 05:09 PMThis 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.

International conference on environment audit - Concerns about water pollution - CAG (2010)
Posted on 10 Sep, 2010 05:15 PM
This link on the CAG website provides the details of an international conference that was held on 15-16 March 2010, in the backdrop of the environmental audit proposed by the the Comptroller and Auditor General (CAG) of India, for management and conservation of the environment .
The purpose of this conference was to deliberate on the causes of pollution, action taken by governments and civil society to address this and environmental, management and legal interventions needed to put lakes, rivers and ground water on the path of sustainability.
More than 20 experts on water and water pollution issues were invited to share their views as panelists during the conference. Apart from these distinguished panelists, the heads of supreme audit institutions from countries like Austria, Maldives, Bangladesh and Bhutan were also present to share their experiences regarding audit of water pollution in their countries.

Hydraulic conductivity: The ability of the rock material to allow the flow of groundwater – A presentation by ACWADAM
Posted on 27 Aug, 2010 08:10 AM
This presentation by ACWADAM on hydraulic conductivity deals with the hydrologic properties of rocks that signify the status of a rock as a good or poor aquifer. The status of a rock with regard to groundwater occurrence and movement is decided by its porosity (specific yield, more practically) and its hydraulic conductivity. These properties decide whether a rock can store and transmit groundwater.
Hydraulic conductivity is also commonly called as permeability of the rock or rock material and is its ability to allow the flow of groundwater through it. A rock with good hydraulic conductivity allows groundwater to easily flow through it.
The presentation describes Darcy’s Apparatus, which comprises of a glass cylinder filled with porous sand. The glass cylinder with the sand bed had an inlet for inflow of water and an outlet for outflow of water. Two vertical glass tubes (manometers) are fitted in the sand tube placed at a fixed distance from each other to measure the respective levels (hydraulic heads).
