This paper on the GIS Development site highlights the findings of a study taken up for the monitoring, identification and suggesting preliminary measures of water pollution cont

This paper published in the Economic and Political Weekly describes the case of river Khari in Gujarat, which faced increasing amount of pollution due to the discharge of industrial effluents in the river and the efforts made  to solve the pollution problem.

The phenomenon of pollution started in the 1970s when Naroda, Odhav, Vatva and Narol on the eastern periphery of Ahmedabad city were promoted by the government. While there were zones for industries according to the type of waste generated, environmental considerations were overlooked and no provision was made for the safe disposal of industrial effluents. Most of the factories in the industrial estates were water intensive and all of them discharged effluents into the nearby Kharicut canal, which flows into the Khari river, a tributary of the Sabarmati. As the canal remained dry throughout the year, the government ignored its (mis)use.

This presentation provides an introduction to the book by the Centre for Science and Environment(CSE) titled Sewage Canal: How to Clean the Yamuna”. As per the presentation, several crore rupees have been sunk into plans to clean up the Yamuna.

The issues presented include – (a) Inter-sectoral allocation (b) Meeting the demand (c) Maintaining quality standards (d) Reducing unaccounted for water (e) Recycle and reuse (f) Promoting rainwater and conservation (g) Implementation of CDS and (f) Is ‘privatisation’, a solution or a disaster?

Micro-watershed level planning requires a host of inter-related information to be generated and studied in relation to each other. Remotely sensed data provides valuable and up-to-date spatial information on natural resources and physical terrain parameters.

These presentations deal with a case study of the work done in Chicago City in the United States of America to improve flood management and water quality. In order to save construction costs, the reservoir side walls are composed of geomembrane liner over compacted clay.

This presentation by the Bangalore Water Supply and Sewerage Board deals with the Environment Action Plan (Part – B) for Bangalore. The presentation begins with a description of the drainage pattern of the city and the major rivers in and around it. The objectives of the EAP are set out as –

• Stopping flow of raw sewage into storm water drains.
• Achieving zero discharge of raw sewage into drains.
• Conveying sewage to treatment plants and treating to meet standards.
• Improving environment.
• Improving socio-economic status.

A ragged-looking Tropical Storm Bijli draped the east coast of India in this image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite on April 16, 2009. Bijli became a tropical storm in the northwest Bay of Bengal on April 15, and initially headed north, toward the west coast of India. By April 16, it had begun a northeastward turn, however, and the storm was being projected to make landfall in eastern Bangladesh on April 17, according to Unisys.
