Water quality monitoring of lakes in and around Bangalore city - A report by KSPCB (2001)
This report by the Karnataka State Pollution Control Board (KSPCB) both in Kannada and English highlights the deteriorating condition of the lakes in and around Bangalore city and describes the efforts undertaken by the Karnataka State Pollution Control Board to launch a programme to monitor the water quality of some of the lakes in Bangalore so as to focus the attention of concerned governmental organisations to take up remedial measures to safe guard the water bodies of the "Garden City".

This report by the Kerala State Council for Science, Technology and Environment (KSCSTE) and Centre for Water Resources Development and Management (CWRDM) on water quality monitoring in Kerala covers all its forty four river basins. This is being done under the “Environmental Monitoring Programme on Water Quality” under which samples are being collected both from surface and groundwater sources.
Groundwater sampling stations were fixed after conducting a sanitary survey in the panchayats. Water Quality Information System is being developed using Geographical Information Systems (GIS) to manage the water quality from point or non-point source of pollution.
In the first phase of the project, three river basins of Kerala viz. Kabbini, Periyar and Neyyar were monitored. The network was later expanded to basins such as Chaliyar, Kadalundi, Meenachil, Karamana, Anjarakandi, Pamba, Muvattupuzha, Bharatapuzha, and Chalakudy.

The Geological Survey of India (GSI) has been preparing state geology and mineral maps as a part of its Miscellaneous Publications series from time to time. During the span of three and a half decades since the first edition was published, enormous knowledge has been added in the sphere of geology of the areas necessitating revisions. The entire modified and updated series published at various points of time is available here.

This flood hazard atlas for the State of Assam prepared by the National Remote Sensing Centre (NRSC) is based on an analysis of ten years of multi-temporal satellite datasets acquired during the flood seasons of 1998-2007.
Assam represents a highly flood-prone region characterized by severe hazards of floods. Although occurrence of flood has been an age-old phenomenon in the riverine areas of this region, the extent of damage caused by floods has increased significantly in recent years.

This article in Geospatial World deals with a geomorphic study of low elevated wards in Bareilly, which indicates that the aquatic ecosystem of an area disappeared due to unplanned development of agro ecosystems and human settlements. This area was earlier covered with ponds, wetlands and ox-bow lakes. Now, during the rainy season, inhabitants of these wards face severe problem of water logging and pollution.

These state-wise atlases on mangrove wetlands were prepared by the M S Swaminathan Research Foundation (MSSRF) under the India-Canada Environment Facility supported project entitled “Coastal Wetlands: Mangrove Conservation and Management”.
The MSSRF project on fostering the sustainable management of mangrove wetlands in the states of Tamil Nadu, Andhra Pradesh and Orissa had yielded valuable results on the quantitative and qualitative aspects of mangrove wetlands with particular reference to the impact of anthropogenic pressures on the ecosystem on the one hand, and the benefits arising from eco-restoration and mangrove rehabilitation programmes on the other. The data have been compiled in the form of GIS maps which have formed the basis for a series of Atlases.
Read MoreRestoration of traditional small water bodies in Braj - The South Asian Journal of Tourism and Heritage
This paper published in the South Asian Journal of Tourism and Heritage begins by highlighting the importance of the traditional small water bodies in Braj, commonly known as kunds, as important freshwater sources as well as an important part of the culture and the traditions of the area.
There were 1000 such kunds, which used to be the source of fresh water in Braj in earlier times. The water was used for multiple purposes like irrigated agriculture, domestic uses, drinking water for cattle, bathing etc. Due to rapid urbanisation, lack of maintenance and prolonged negligence in the last 50-100 years, most of the kunds today have become silted up and are nearing extinction.
The impending crisis for fresh water has forced the planners and policy makers to take cognizance of these traditional water bodies and an urgent need has been identified for taking necessary measures to restore the kunds. The present study thus aims at understanding the reasons for deterioration of the kunds and makes some technical suggestions for revival of these kunds. Read More
