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.

Forwarded to the Portal by Dr.Vijay Verma

You are well aware that Dr. G D Agarwal aged 79 years Scientist, Environmentalist, Bureaucrat and Saint is on fast unto death from 20th July 2010 at Matri Sadan, Haridwar. His fragile age will not permit to endure long days of fast. It seems we are waiting for his demise.

National River Ganga Basin Authority (NRGBA) is formed to fool people of India as this is happening since Independence.

Soil erosion studies for forested watersheds – A research report by National Institute of Hydrology
This study attempts to estimate the soil erosion rate in Malaprabha representative basin in Karnataka, by using WEPP model and Universal Soil Loss Equation. Posted on 24 Jul, 2010 10:09 PM

In the present study, an attempt has been made to estimate the soil erosion rate in Malaprabha representative basin by using WEPP model and Universal Soil Loss Equation. Soil erosion and sedimentation are the two important natural processes, which need immediate attention from the scientific community. Two major types of erosion are geological erosion and erosion from human or animal activities.

Characteristics of short interval rainfall for Punpun basin in Bihar – A research report by National Institute of Hydrology
In this study, an attempt has been made to study the characteristics of short interval rainfall data of the Punpun river basin lying in Bihar-Jharkhand. Posted on 24 Jul, 2010 09:50 PM

In this study, an attempt has been made to study the characteristics of short interval rainfall data of the Punpun river basin lying in Bihar-Jharkhand, which has been identified as the representative basin for the NIH- Centre for Flood Management Studies, Patna. The estimation of flood peaks for small catchments is required for water resources planning, flood forecasting, design of various drainage systems, flood control and design of hydraulic structures.

Analysis of surface runoff and baseflow at Tambarapani basin – A research report by National Institute of Hydrology
The report presents the analysis of surface runoff and baseflow carried out for the Ariyanayakipuram anicut, Tambarapani basin, Tamil Nadu for a period of 13 years (1983-95). Posted on 24 Jul, 2010 09:12 PM

The report presents the analysis of surface runoff and baseflow carried out for the Ariyanayakipuram anicut, Tambarapani basin, Tamil Nadu for a period of 13 years (1983-95). The hydrological behavior of catchments is a very complex phenomenon and is controlled by a large number of climatic and physiographic factors that vary in time and space. The analysis shows that the contribution of baseflow at Ariyanayakipuram anicut was observed to be more.

Estimation of infiltration rates in the Suddagedda basin of East Godavari, AP – A research report by National Institute of Hydrology
The report on Suddagedda basin, a representative basin of the east flowing rivers, presents the outcomes of the infiltration tests carried out using Double Ring Infiltrometer. Posted on 24 Jul, 2010 06:01 PM

The report on Suddagedda basin, a representative basin of the east flowing rivers of medium sized basins in the east coast of India, presents the outcomes of the infiltration tests carried out using Double Ring Infiltrometer. The basin soil is mainly grouped into three types viz clay loams to clay, sandy loams and forest & loamy skeletal. A total of twenty-eight infiltration tests have been conducted using double ring infiltrometers.

Daily rainfall-runoff modeling of Brahmani river at Rengali reservoir, Orissa – A research report by National Institute of Hydrology
The report presents a hydrologic simulation model, HYSIM for modelling the daily flows of the Brahmani river at Rengali reservoir in Orissa. Posted on 24 Jul, 2010 05:50 PM

The report presents a hydrologic simulation model, HYSIM for modeling the daily flows of the Brahmani river at Rengali reservoir in Orissa. Considering the large catchment area of 25,250 sqkm at Rengali reservoir, for modeling purposes the basin has been divided into two sub-basins viz, Upper Sub-basin and Lower Sub-basin. The Upper Sub-basin having a catchment area of 16,900 sqkm up to Bolani gauging site is treated as a nominal sub-basin since the daily flows from this sub-basin as recorded at Bolani gauging site are available.

Hydrological soil classification in Sher-Umar river doab in Narmada basin – A research report by National Institute of Hydrology
The report deals with hydrological soil classification in Sher-Umar river doab in Narmada basin in Madhya Pradesh. Posted on 24 Jul, 2010 05:35 PM

The report deals with hydrological soil classification in Sher-Umar river doab in Narmada basin. The study and classification of soil has in the past been undertaken by engineers and agriculturists who have confined themselves to those soil properties and materials in which they had a special interest. The soils have also been studied by geologists, but the geological description of an area does not include the information required by soil scientists. The classification designed by soil users have tended to be of limited value to others as they were designed to serve a specific and limited purpose.

Derivation of Geomorphological Instantaneous Unit Hydrographs for small catchments in hard rock regions - A research report by National Institute of Hydrology
In this study, Clark model parameters to geomorphological characteristics has been used to develop Geomorphological Instantaneous Unit Hydrographs for two hard rock catchments. Posted on 24 Jul, 2010 10:31 AM

In the study, the methodology developed at the National Institute of Hydrology to relate Clark model parameters to geomorphological characteristics has been used to develop unit hydrograph for two hard rock catchments, Barchi nala and Malaprabha up to Khanapur. This model has already been successfully implemented for simulation of flood events in small catchments of Upper Narmada and Kolar sub-basin of Narmada river as well as the Tapi sub-zone.

Estimation of soil erosion and sediment yield in Karso catchment of Barakar basin in Jharkhand using ANSWERS model - A research report by National Institute of Hydrology
The report presents an estimation of soil erosion and sediment yield for the Karso catchment of Barakar basin in Jharkhand using ANSWERS model. Posted on 24 Jul, 2010 10:21 AM

The report presents an estimation of soil erosion and sediment yield for the Karso catchment of Barakar basin in Jharkhand using ANSWERS model. Quantitative assessments of runoff and soil erosion are needed for proper management of land and water resources.
