Points of groundwater discharge: Types of springs – A presentation by ACWADAM
Posted on 26 Aug, 2010 08:52 PMThis presentation by ACWADAM deals with springs, their characteristics and types. Springs are indicated by locations or points on the ground surface, where water from beneath the ground emerges on to the surface. A common example is of an overflowing unconfined aquifer.
Some of the characteristics of springs are:
- Discharge from spring may be constant or variable.
- Springs can be perennial or seasonal.
- Discharge from a spring may vary between from a trickle to about 100 cum per second.
- Difficulty in access.
- Variation in discharge.
- Temperature of spring water may vary from mean atmospheric temperature to lower or higher, even boiling temperatures. Hot quality water springs are common to many parts of the world.

Pani Panchayat: A model of groundwater management – A presentation by ACWADAM
Posted on 25 Aug, 2010 08:20 AMThe presentation by ACWADAM deals with Pani Panchayats as a model of groundwater management.
Pani Panchayat is the name first given to a movement by Mr. Vilasrao Salunke for motivating farmers of Naigaon village of the drought-prone Purandhar taluka of Maharashtra in 1974. The government's inability to deal with the drought situation prompted him to take a 40 acre land on lease from the village temple trust and develop a recharge pond in the recharge area of the village, a dug well in the discharge zone and a lift irrigation system.
Farmers got impressed with the results demanding a scale up of the experiment leading to the setting up of Gram Gaurav Pratisthan (GGP) through which the work was expanded to encompass both groundwater and surface water management.
Augmenting groundwater resources by artificial recharge: A case study of Kolwan valley by ACWADAM
Posted on 24 Aug, 2010 04:19 PMThe 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:
- 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.
Pumping tests on wells: A means of measuring the storage and transmission properties of aquifers
Posted on 24 Aug, 2010 10:03 AMThe presentation by ACWADAM is part of the training module developed by them on “Planning, development and management of groundwater with special reference to watershed management programmes”. Pumping a well and observing the effect of such pumping on the water level in the pumped well as well as in the adjoining parts of the aquifer through observation wells is the basic procedure involved in a pumping test.
Is irrigation water free? A reality check in the Indo-Gangetic Basin – A working paper by the Challenge Program on Water and Food
Posted on 17 Aug, 2010 09:41 PMThe paper generated under the Challenge Program for Water and Food (CPWF) project explores in some depth a totally different dynamic in the irrigation economy of the vast Indo-Gangetic basin (IGB), an important exception to the global characterization. The global debate on ‘‘water as an economic good’’ presumes that irrigation water supply is delivered, controlled, and priced by public institutions. In the developing world, the price of water is kept so low that water use cost leaves farmers no incentive to use it efficiently.
Indo-Gangetic river basins: Summary situation analysis by Challenge Program on Water and Food
Posted on 16 Aug, 2010 07:37 PMThe paper by the Challenge Programme on Water and Food (CPWF) - Basin Focal Project provides a brief situation analysis related to water, agriculture & poverty, water resources, water productivity, institutional aspects and opportunities & risks related to the development of the Indo-Gangetic basin (IGB). Management of IGB water resources presents some formidable challenges and, therefore, steps must be taken towards integrated management of the IGB’s water and land resources in order to ensure the future sustainability of all production and ecosystems in the basin.
Increasing groundwater dependency and declining urban water quality – A comparative analysis of four South Indian cities
Posted on 15 Aug, 2010 07:18 AMThis paper by the Institute of Social and Economic Change (ISEC) examines the extent of groundwater dependency and quality status in four South Indian cities viz., Hubli, Dharwad, Belgaum and Kolar cities. Widespread water shortage problems have resulted in increased dependency on groundwater with tapping the resources to unsustainable levels. In Karnataka, out of 208 urban local bodies that come under Karnataka Urban Water Supply and Drainage Board, 41 depend on groundwater.
Water Initiatives Orissa dated on 5th August 2010
Posted on 11 Aug, 2010 12:18 PMWIO Urges the Government of Orissa to come out with a While Paper on state and availability status of water resources in the state. The demand comes in the wake of the government's consistent claim that the state is water surplus even though water scarcity hits us all every day.
Sambalpur, 5th August 2010 - As the industrial overdrive of Orissa continues with signing of MoU after MoU with water guzzling industries, there is no clarity on the exact water available in the state. The government has been propagating that Orissa is a water surplus state. However, statistics used by the various reports of the government are dated to 2001, from when the real industrialization boom has taken off in the state. It is time that the government comes out with a transparent position paper on the exact water availability in the state or else water conflicts will aggravate.
Floods, drinking water contamination, mining and waterbodies, water bills, water conflicts - News roundup (1-7 August 2010)
Posted on 07 Aug, 2010 04:51 PMFloods: lessons to be learnt from the massive flooding in Surat city
A report by IIM criticises the way in which dams are managed in the country and calls for the need to apply Management Science / Operations Research techniques and information technology to improve dam management and prevention of floods
Groundwater and well water quality in alluvial aquifer of Central Gujarat - A paper by CAREWATER
Posted on 03 Aug, 2010 08:58 PMThe report by Carewater INREM Foundation deals with groundwater and well water quality in the alluvial aquifers of Central Gujarat. Gujarat has a hydrogeology representative of almost all aquifer types and depositional & formation eras. Contamination of aquifers along with scarcity of groundwater resources due to increase in water demand and reduction in recharge of groundwater from changing landuse, is a problem in Central Gujarat.
