LABORATORY
started his research career by focusing on
various aspects of river basin geochemistry (water
quality & quantity, river discharge, sediment load, sediment
characteristics (physico-chemical) estimation of erosion rates
and accumulation of sediments, pollution). Later, he started
his research program on coastal ecosystem namely estuaries,
mangroves and coral reefs Viz., Pichavaram, Bhitarkanika, Sundarban and Gulf of
Mannar and Kutch focusing on biogeochemical aspects.
He has also worked on several projects of sheer importance
such as :
Hydro-geochemistry of ground
waters (inland and coastal) addressing salinity, fluoride, SGD,
Pollution etc. (Including De- fluoridation
techniques (phyto, nano etc., )
Land use changes and over
exploitation of ground water
due to Neyveli lignite mining (EIA studies); Natural Hazards,
Like Tsunami impacts on coastal ecosystem & ground water)
Surface and ground
water interaction (quality ) in coastal areas
and flood
plains
(Ganges and Yamuna)
The
Effect of Climate Change
on Indian Glaciers
(case study from large
glacier like Gangotri (Uttaranchal) and Small glaciers like
Chhota Shigri, Patchio (Himachal Pradesh)
The effect of landfills on the
groundwater quality and GHGs emission in Delhi
Arsenic problem
and Fluoride remediation (Tamilnadu) and in various parts
of India (UP, Bihar, Jharkhand,
West Bengal and Manipur)
Apart from Hydrogeochemistry and Biogeochemistry, Prof.
Ramanathan has been working intensively on Dynamics of Himalayan Glaciers (such
as mass balance, energy balance, hydrology and hydrogeochemistry
). His work is well recognized throughout the world.
Prof. Ramanathan
has published more than seventy five papers in
various peer reviewed journals such as (Journal of Glaciology, J. Hydrology, Hydrological
processes, Water resources, Estuarine coastal and shelf Sciences, Chemosphere, Bioresource Technology, Geoderma
etc). He has published seven
books (Springer, Balkema, etc., ) and a number of
papers have been published as book chapters. Prof. Ramanathan
has conducted eleven International /National workshop /training
programme /conferences on various theme of sheer importance. His work has been well
supported by various national (UGC, DST, MoEF, MoWR etc) and
international funding organization (SIDA, IFS, FORMAS, JAMSTEC,
Indo-Australia fund-AIMS). He has running/completed
collaborative projects with institutions from France,
Sweden, Australia and Russia. Fifteen PhDs and more than fifteen
M.Phil. (have been completed under his supervision and are well
placed in India and abroad.
