Choppy waters and a calm river voyager
Posted on 06 Dec, 2015 12:31 PMThe epic voyage--Nadisutra--along the Ganga may have been the high point of Emmanuel Theophilus’s recent work, but there have been many more peaks and valleys for this fervent mountaineer cum ecologist. Theo lives in a remote village near Munsiyari in Uttarakhand.

Adsorption of lead and zinc ions on sediments - A research report by National Institute of Hydrology
Posted on 29 Jun, 2010 10:53 PMThe study deals with adsorption of lead and zinc ions on the bed sediments of river Kali in western Uttar Pradesh. Adsorption is one of the most important processes in water quality control, which influences the transport of pollutants in aquatic environment.
Surface water quality assessment of river Kali with special emphasis on non point source of pollution – A research report by the National Institute of Hydrology
Posted on 20 Jun, 2010 11:52 PMThe study conducts an extensive water quality survey in sixteen reaches of Kali river in western Uttar Pradesh to estimate the inflow of two major nutrients (nitrate and phosphate) from point and non-point sources. The study intends to validate the present model based on the principle of conservation of mass and reaction kinetics phenomenon.
Data was taken for one annual cycle on a monthly basis and criteria developed to compute the non point source load from nine sub-basins in various stretches of the river. The computed loads at each section obtained from the predictive equation have been compared with the values observed in the field. The performance of the developed equation has been evaluated using percentage error estimation and correlation statistics. Remote sensing and geographical information systems (GIS) have been used to develop correlation between basin characteristics and non-point source loads.
