Mitigation and remedy of groundwater arsenic menace in India: A vision document by NIH and CGWB (2010)
What should be gaps, focal areas of research, immediate measures to be taken up to provide arsenic safe potable water to the people? This document details and outlines Amita Bhaduri posted 10 years 11 months ago

This document, an outcome of the joint efforts of NIH and CGWB gives a detailed outline emphasizing the gaps, focal areas of research, immediate measures to be taken up to provide arsenic safe potable water to the people in the arsenic vulnerable areas, other activities to be initiated for attaining a logical conclusion of the arsenic problem and also to develop a roadmap delineating as to how the suggested activities could be initiated, coordinated, undertaken, including framing out a budget estimate to fulfill those activities.

Modeling of a coastal aquifer in Goa using FEFLOW – A research report by National Institute of Hydrology
Modeling sea water in Goa to evaluate increase in groundwater development Amita Bhaduri posted 11 years 3 months ago

The study by National Institute of Hydrology attempts to model seawater intrusion using FEFLOW, an interactive finite element simulation system in the coastal area of Bardez taluka in North Goa and evaluate the impact of increasing groundwater development on the phenomenon. Coastal tracts of Goa are rapidly being transformed into settlement areas and the poor water supply facilities have encouraged people to develop their own sources of water by digging or boring wells.

Simulation of soil moisture movement in Barchi watershed in hard rock region of Karnataka using SWIM model – A research report by National Institute of Hydrology
Simulation of soil moisture movement and determination of groundwater recharge from rainfall Amita Bhaduri posted 11 years 3 months ago

This study by the National Institute of Hydrology deals with simulation of soil moisture movement and determination of groundwater recharge from rainfall in Barchi watershed in the hard rock region of Karnataka using the numerical model, Soil Water Infiltration and Movement (SWIM).

Research reports of the National Institute of Hydrology (1996-2001) - Highlights

The India Water Portal is pleased to announce to its users, that a comprehensive archive of over two hundred and fifty technical research reports of the National Institute of Hydrology (NIH), Roorkee, have now been made available on the portal, and in the public domain for the first time.

Estimation of rate and pattern of sedimentation and useful life of Dal Nagin Lake in Jammu and Kashmir - A research report by National Institute of Hydrology
The study determines rates of sedimentation and estimates the useful life of Dal-Nagin lake situated in Srinagar, Jammu and Kashmir using radiometric techniques. Rama Mani posted 11 years 3 months ago

The study determines rates of sedimentation and estimates the useful life of Dal-Nagin lake situated in Srinagar, Jammu and Kashmir using radiometric techniques. In spite of various ecological problems the lake is the largest freshwater lake in India. It has four major sub-basins viz., Hazratbal, Bod Dal, Garibal and Nagin. The lake is fraught with the problem of growth of underwater weeds and increasing rate of sedimentation.

Development of operation policy for Tawa dam – A research report by National Institute of Hydrology
The study deals with the development of an operation policy for the Tawa da, Madhya Pradesh, which adopts rule-curve based policy for conservation regulation of the dam. Rama Mani posted 11 years 3 months ago

The study deals with the development of an operation policy for the Tawa dam. It adopts rule-curve based policy for conservation regulation of the dam developed for three levels viz. upper rule level, middle rule level (critical for irrigation) and lower rule level (critical for water supply and upstream use). The generated simulation model developed by the Water Resources System Group at the National Institute of Hydrology is used to simulate the system operation and to refine the rule curves.

Flood plain mapping in a part of Yamuna basin – A research report by National Institute of Hydrology
The study deals with flood plain mapping in a part of Yamuna basin between Gangoh and New Delhi, which is inundated by a flood of given frequency. Rama Mani posted 11 years 3 months ago

The study deals with flood plain mapping in a part of Yamuna basin between Gangoh and New Delhi. A flood is a markedly high stage of flow in a river and may inundate adjoining lands, which is called the floodplain of a river. So, floodplain is land inundated by a flood of given frequency. Alternately it is also defined as flat land between valley walls.

Application of HEC – 2 programme for water surface profile determination of river Digaru at Sonapur – A research report by National Institute of Hydrology
In this study, HEC 2 programme has been implemented on river Digaru in Sonapur, Assam, to compute flow regime or the water surface profile for various discharge conditions. Rama Mani posted 11 years 3 months ago

In this study, HEC 2 programme has been implemented on river Digaru to compute flow regime or the water surface profile for various discharge conditions. In this reach, two bridges have been considered to compute water surface elevations, critical water surface elevations, energy grade elevations & slope, velocity in the channel, flow area, top width and Froude Number.

Groundwater balance for the Southern Channel command area of the Pennar delta canal system – A research report by National Institute of Hydrology
The report presents the groundwater balance for the Southern Channel command area of the Pennar delta canal system in Andhra Pradesh as a part of the conjunctive use studies in the area. Rama Mani posted 11 years 3 months ago

The report presents the groundwater balance for the Southern Channel command area of the Pennar delta canal system as a part of the conjunctive use studies in the area. In a hydrological system, surface water flows, low or high, do not necessarily coincide with the low or high levels in groundwater, because of the sluggishness of the groundwater flow compared to surface water flow.

Dam break study of Barna dam – A research report by National Institute of Hydrology
The study deals with dam break analysis of Barna dam in Madhya Pradesh carried out using the popular NWS DAMBRK model to assess the likely maximum flood discharge . Rama Mani posted 11 years 3 months ago

The study deals with dam break analysis of Barna dam located in the state of Madhya Pradesh carried out using the popular National Weather Service Dam Break Flood Forecasting (NWS DAMBRK) model to assess the likely maximum flood discharge and elevation to be attained in Bareli township, 22 km downstream of the dam.
