Impacts of groundwater contamination with Fluoride and Arsenic: A report by CAREWATER
Posted on 04 Aug, 2010 10:25 AMThe field research study conducted by Carewater INREM Foundation attempts to establish the impacts of groundwater contamination with fluoride and arsenic in India. It maps the affliction severity, the medical cost and wage loss through a multi-location study in some villages in the States of Rajasthan, Andhra Pradesh, Karnataka and West Bengal.
Possibility of revival of dug wells in hard rock India through recharge: A discussion paper by CAREWATER
Posted on 03 Aug, 2010 08:07 PMThe discussion paper by Carewater INREM Foundation on possibility of revival of dug wells in hard rock India through recharge is based on a field study across ten districts of the country. The study seeks to understand how localized governance of groundwater in hard rock areas is to be pursued through pricing (water, energy), legal regulation and community institutions. Water supply augmentation and demand management are both to be taken care of, directly through regulation or through indirect instruments such as pricing.
Water sector and reforms - Report of workshop organised by CASUMM (2007)
Posted on 02 Aug, 2010 12:08 AMThe workshop was organised in response to the implementation of two water supply projects in Bangalore and Mysore as a part of the Water Sector Reforms under the Jawaharlal Nehru National Urban Renewal Mission (JNNURM) and the increasing trend of privatisation under the water sector reforms in cities like Bangalore and Mysore.
It was felt that there was a need to raise awareness among citizens and groups in Bangalore and Mysore regarding the implications of privatisation and the mechanisms through which privatisation was being introduced in the cities in India.
Water challenges in Greater Bangalore - NIAS-CASUMM workshop note (2007)
Posted on 01 Aug, 2010 03:36 PMThis document provides the background for a workshop on 'Water Challenges in Greater Bangalore', organised by NIAS and CASSUM at the National Institute of Advanced Studies (NIAS), Indian Institute of Science (IISC) campus on March 27, 2007.
The document highlights the current scenario of privatisation of water services that are being funded by international financial institutions under the water sector reforms in the city of Bangalore, which have had a very negative impact on the urban poor, who continue to face the problem of inadequate, unreliable and unsafe water supply as compared to other posh and water rich areas in the city.
GIS based rainfall-runoff modeling for Hemavathy catchment – A research report by National Institute of Hydrology
Posted on 29 Jul, 2010 09:19 PMThe report deals with Geographical Information Systems (GIS) based rainfall-runoff modeling using Topography Model (TOPMODEL) for the Hemavathy catchment of Cauvery basin in Western Ghats of Karnataka. The TOPMODEL is a variable contribution area model in which the predominant factors determining the formation of runoff are represented by the topography of the basin and a negative exponential law linking the transmissivity of the soil with the vertical distance from the ground level.
Analysis of surface and groundwater flow process in Western Ghat of Dakshina Kannada district of Karnataka – A research report by National Institute of Hydrology
Posted on 29 Jul, 2010 09:04 PMThe study deals with the analysis of surface and groundwater flow process in Dakshina Kannada district in Western Ghats of Karnataka. The area receives over 4000 mm rainfall annually but is still faced with acute shortage of freshwater during summer months. The study attempts to identify the surface and sub-surface flow process through geohydrological and geomorphological investigations in the Sithanadhi and Netravathi basins.
Estimation of surface soil properties in Malaprabha command area – A research report by National Institute of Hydrology
Posted on 27 Jul, 2010 08:42 PMThe study deals with estimation of surface soil properties in Malaprabha command area. It can be broadly concluded that generalization of soil properties for an area is difficult since the soil and land use type varies drastically from one point to another in a short distance. It is only possible to have an average value for a particular type of soil. Also, it can be seen from the results that the percentage of silt-clay plays an important role in shaping the hydraulic properties of a soil.
Tank study in Belgaum district of Karnataka– A research report by National Institute of Hydrology
Posted on 27 Jul, 2010 08:30 PMThe report presents a study of the Rakaskop tank, which caters to the drinking and domestic water purposes of the Belgaum city of Karnataka. In recent past, it has been observed that the amount of water stored during the monsoon season is not sufficient for domestic purposes in the city throughout the year. The study estimates the dependable yield of the tank and also the evaporation from the tank.
Groundwater quality modeling in Nargund-Navalgund area of Malaprabha command – A research report by National Institute of Hydrology
Posted on 27 Jul, 2010 05:48 PMIn this report, groundwater quality scenarios of the worst affected region of Nargund-Navalgund area of Malaprabha command in Dharwar, Karnataka have been simulated through a three dimensional finite difference code SWIFT III. Mathematical modeling of the groundwater quality was done on a local rather than a larger regional scale.
A sudy of the core of a riverine system and relevance of meltwater in river basin hydrology
Posted on 25 Jul, 2010 10:44 PMMy house is about 20 years old and is located in R T Nagar in Bangalore. In 1990, I had got a borewell dug. The Borewell is about 150 feet deep and has been giving me excellent quality water until about 2 years ago when I started noticing muddy water. The water that is pumped to an overhead tank contains fine particles of mud which tends to settle down in the overhead tank.
