Rivers

To provide the background hydrological information for the assessment of environmental flow requirements at four selected ‘Environmental Flow’ sites, a hydrological model was set up to simulate the catchment in the present state (with water regulation  infrastructure) and to generate the natural flows (without water regulation infrastructure).

This paper published in the Indian Journal of Traditional Knowledge makes an attempt to record the fisheries related indigenous technological knowledge in terms of fishing crafts and gears used in river Krishna.

This paper in the Journal of Earth System Science deals with a study by National Institute of Oceanography (NIO), Goa to investigate the influence of monsoonal rainfall on hydrographic conditions in the Mandovi River of India. The study was undertaken at a location approximately 2 km upstream of the mouth of the estuary.

This paper in Journal of Earth System Science deals with paleochannel and paleohydrology of the Middle Siwalik (Pliocene) fluvial system in Northern India. In recent years, fluvial sedimentologists have carried out numerous studies to estimate quantitative hydrodynamics of ancient fluvial systems, particularly, their morphology and hydrology. The methods for reconstructing the morphology and hydrology employ either several groups of empirical relationships derived from modern fluvial environments or dynamic models of fluvial flow and sediment transports in alluvial reaches.

This paper in Journal of Earth Systems Science deals with uncertainties in downscaled relative humidity for a semi-arid region - Malaprabha basin in India. Researchers and decision-makers who assess the impact of climate change in river basin development, agriculture, hydrology, irrigation management, etc., require future scenarios of relative humidity.

The Level-I Laboratories are located at 258 field water quality monitoring stations on various rivers of India where physical parameters such as temperature, colour, odour, specific conductivity, total dissolved solids, pH and dissolved oxygen of river water are observed.

Kosi is known as the sorrow of Bihar due to its frequent and often disastrous floods. The major geomorphic units of flood-inundated area in Kosi fan (terrain of Kosi river in India) are sand bars in the form of inter-connected drainage networks, an ox-bow lake and its meandering cut-off and imprint.

This report presents the results based on climate change scenarios and identifies potential adaptation strategies. The study is part of the ‘Climate Change Impacts on Freshwater Ecosystems in the Himalayas’ (CCIFEH) project, a joint initiative of WWF-India and WWF-Nepal, supported by WWF-Netherlands and aims to study and understand climate change impacts on freshwater ecosystems, livelihoods and the economy.

Change in climate conditions and the frequency of natural disasters in recent times has made it imperative to find lasting adaptation solutions for the agriculture sector. Given that almost 60 per cent of the country’s population relies on this sector for its livelihood and that it contributes approximately 15.7 per cent of India’s GDP, an analysis of changes which could impact crop yields and subsequently lead to an instable food security scenario is necessary.
