Derivation of Geomorphological Instantaneous Unit Hydrographs for small catchments in hard rock regions - A research report by National Institute of Hydrology
Posted on 24 Jul, 2010 10:31 AMIn 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
Posted on 24 Jul, 2010 10:21 AMThe 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.
Study of soil moisture movement and recharge to groundwater using tritium tagging techniques in Saharanpur - A research report by National Institute of Hydrology
Posted on 24 Jul, 2010 10:05 AMThe present study aims to estimate the soil moisture movement and recharge to groundwater in Saharanpur due to monsoon rains through the unsaturated porous media in case of cultivated and uncultivated fields. Artificial radioisotope was injected at two uncultivated and five cultivated sites before the onset of monsoon and soil samples were collected from the injection points after the rainy season.
Hydrogeological and geochemical studies of groundwater flow in Suddagedda basin – A research report by National Institute of Hydrology
Posted on 24 Jul, 2010 12:18 AMThe report presents a hydrogeological and geochemical study of groundwater flow for the Suddagedda basin of Andhra Pradesh. Planning of water resources development projects calls for an understanding and analysis of the hydrological characteristics of the region. The hydrogeology and geochemistry of the basin needs to be investigated particularly for a groundwater resources development project.
Relevance of Meltwater in River Basin Hydrology
Posted on 23 Jul, 2010 10:53 PMA peer paper in Science Magazine focuses on the core of a riverine system, the upstream basin, and its impact on the entire river basin.
Regional model for annual runoff estimation - A research report by National Institute of Hydrology
Posted on 23 Jul, 2010 10:40 PMThe report presents a seasonal rainfall-runoff model developed for the Saurashtra region as well as parts of Narmada river basin. The successful planning and implementation of water resources projects require reliable data on volumetric runoff. It is not feasible to have discharge stations in all the river basins of interest given resource constraints. Therefore, regional rainfall-runoff models are preferred. The utility of such models can be improved if rainfall-runoff models for different regions are developed using data specific to the regions.
Surface and groundwater quality evaluation in parts of Udhampur district – A research report by National Institute of Hydrology
Posted on 23 Jul, 2010 08:29 PMIn the present study, surface and groundwater quality monitoring has been undertaken in parts of Udhampur district in Jammu and Kashmir in order to evaluate its quality for domestic and agricultural purposes. Water sources are polluted by four kinds of substances: traditional organic waste, waste generated from industrial processes, chemical agents of fertilizers & pesticides used for crop production and silt from degraded catchment.
Proposing a National River Authority of India (NRAI)
Posted on 23 Jul, 2010 04:29 PMIntervening at the urgency of the water situation of the country and need in larger interest of the people and nation from political, legal, social, administrative, commerce,trade,cultural, world tourism angles, apart from agricultural and drinking water angle; annual devastation by floods,and loss by drought. One single Authority, with P.M. as Chairman may hopefully bring expected and good results in river management; riverine rejuvenation - National River Authority of India
Here is a draft proposal for such an authority to be created.
We are looking for collaborations on making this a reality.
Please post your comments.
Evaluation of groundwater table and quality in Krishna delta of Andhra Pradesh – A research report by National Institute of Hydrology
Posted on 22 Jul, 2010 07:45 AMThe report attempts to analyze the shallow groundwater table and water quality data for about 20 years pertaining to the Krishna delta. The trend analysis of groundwater level data of shallow wells indicates that in the upper part of the delta, the groundwater table moved up during the period 1979 to 1999. This may be due to the dense canal network in the delta and increase in irrigated area over a period of time.

Shankracharya designate Swami Avimukteshwaranand ji presided over an emergency meeting organized by Manushi Sangathan, Ganga Ahvaan and Ganga Yamuna Jal Biradri to express our strong protest against the patently illegal decision of the Group of Ministers giving clearance to the Loharinag-Pala dam on the Ganga River. The following expert members of the NGRBA also participated in the meeting to express their strong protest having been kept in the dark about the appointment of the GoM which has passed a virtual death sentence on the most sacred river of India: Rashid Hyatt Siddiqui, Rajendra Singh, Rama Raota and Ravi Chopra.
