October 30, 2022 This book by Dr. Mitul Baruah presents a fascinating, ethnographic account of the challenges faced by communities living in Majuli, India, one of the largest river islands in the world, which has experienced immense socio-environmental transformations over the years, processes that are emblematic of the Brahmaputra Valley as a whole. This is an excerpt from the book.

The report presents the hydrologic information and news available from print media and various government agencies mostly for the year 1999-2000 compiled problem-wise and basin-wise for the whole country.

Identification of water quality monitoring sites on Kshipra river, Ujjain, MP – A research report by National Institute of Hydrology
The study deals with identification of water quality monitoring sites on Kshipra river of Ujjain, MP. Posted on 28 Jul, 2010 07:18 PM

The study deals with identification of water quality monitoring sites on Kshipra river of Ujjain. The location of permanent sampling station is probably the most critical factor in a monitoring network which collects water quality data. If the samples collected are not representative of the water mass, the frequency of samplings as well as the mode of data interpretation and presentation become inconsequential.

Hydrologic soil classification of Dudhnai sub-basin – A research report by National Institute of Hydrology
The report presents the hydrologic soil classification of Dudhnai sub-basin based on regional information collected from various agencies. Posted on 28 Jul, 2010 04:41 PM

The report presents the hydrologic soil classification of Dudhnai sub-basin based on regional information collected from various agencies supplemented by field and laboratory experiments on the soil samples collected from time to time. As required by various soil classification systems, soil properties together with other information have been studied and grouped into different classes as a reference base for future hydrological studies of the basin.

Identification of sampling sites for water quality monitoring in Narmada basin – A research report by National Institute of Hydrology
The report attempts to identify sampling sites for water quality monitoring in Narmada basin in order to assess the water quality conditions over a wide area. Posted on 27 Jul, 2010 11:52 PM

The report attempts to identify sampling sites for water quality monitoring in Narmada basin. The assessment of water quality conditions over a wide area with respect to time and space requires the monitoring of activities to be carried out in a network. The location of a permanent sampling station is probably the most critical factor in a monitoring network which collects water quality data. If the samples collected are not representative of the water mass, the frequency of sampling as well as the mode of data interpretation and presentation becomes inconsequential.

Determination of SCS runoff Curve Number and land use changes for Hamidnagar sub-basin of Punpun basin – A research report by National Institute of Hydrology
The report deals with determination of SCS runoff Curve Number and land use changes for Hamidnagar sub-basin of Punpun basin in Jharkhand. Posted on 27 Jul, 2010 11:33 PM

The report deals with determination of SCS runoff Curve Number and land use changes for Hamidnagar sub-basin of Punpun basin. The design of any hydraulic structure calls for the estimation of runoff. The Soil Conservation Services model, developed by USDA, computes direct runoff through an empirical equation that requires the rainfall and watershed coefficient as inputs. The watershed coefficient is called the Curve Number (CN), which represents the runoff potential of the land cover-soil complex.

Estimation of surface soil properties in Malaprabha command area – A research report by National Institute of Hydrology
The study deals with estimation of surface soil properties in Malaprabha command area in Karnataka, where, the soil and land use type varies drastically from one point to another in a short distance. Posted on 27 Jul, 2010 08:42 PM

The 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.

Modeling of Cochin estuary using two dimensional finite element model – A research report by National Institute of Hydrology
The report deals with the modelling of the Cochin estuary along Kerala coast using two- dimensional finite element model. Posted on 27 Jul, 2010 08:07 PM

The report deals with the modeling of the Cochin estuary along Kerala coast using two- dimensional finite element model. The basic equations for modeling of any surface water problems are the three dimensional hydrodynamic equations arising from consideration of mass and momentum conservation. In vertically well mixed shallow water bodies, the horizontal components of flow quantities are normally much more significant than vertical components.

Groundwater modeling in Ghataprabha sub-basin of Krishna river basin – A research report by National Institute of Hydrology
In this study, a two layered finite difference method has been generated for groundwater flow analysis of Ghataprabha sub-basin of Krishna river basin. Posted on 27 Jul, 2010 07:58 PM

In this study, a two layered finite difference method has been generated for groundwater flow analysis of Ghataprabha sub-basin of Krishna river basin. The conceptual model has been calibrated for steady state conditions and validated for both steady state and transient conditions through USGS, 3D Finite Difference Code and MODFLOW. Various applications were tried out on the calibrated model, like River-Drain influencing the aquifer, reasons for waterlogging and drying out of wells and well design strategies.

Dr. G. D. Agrawal , the scientist, environmentalist and rishi
Dr. Agarwal - an Inspiring teacher, a humble man and the most-sought-after environmentalist Posted on 27 Jul, 2010 03:52 PM

Dr. G. D. Agrawal Scientist and Rishi

Meeting Dr. G. D. Agrawal in his spartan, two room cottage in Chitrakoot, Madhya Pradesh, you would never guess what an accomplished and distinguished scientist he is – first Member-Secretary of the Government of India’s Central Pollution Control Board, former Head of the Department of Civil and Environmental Engineering at IIT Kanpur and a PhD from the University of California, Berkeley. The list goes on and on.

Yet this eminent professional sweeps his own floors, washes his own clothes and cooks his own meals. He retains only a few possessions and dresses in homespun khadi. At the age of 76, his main mode of transport within Chitrakoot is a bicycle and when he travels further afield, he goes by ordinary bus and second-class train. These are the deliberate choices of a devout Hindu whose deepest values are for simplicity and reverence for nature. Dr G.D. Agrawal is the doyen of environmental engineering professionals in India. Well past retirement, he continues to teach and inspire students as an Honorary Professor of Environmental Sciences at the Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, in Chitrakoot (M.P.).
