Geomorphologically, the mighty Brahmaputra River system flows over the Quaternary sediments. This is a cause of concern because of its location in an abundant monsoon regime within an active seismogenic volume. Since time immemorial, the Brahmaputra has continued to wreck havoc through repeated floods year after year. The flow regime …
Das et al.1 have studied clay mineralogy, terrigenous and biogenic components of the sediment core collected from the Ocean Drilling Programme site 728A, northwestern continental margin of the Arabian Sea, off Oman. Their main objectives were to understand palaeoclimatic conditions, such as monsoons fluctuations, weathering processes and transport pathways of …
As the monsoon retreats and the flood waters recede, the flood bank and bed of the River Dikrong in Itanagar, Arunachal Pradesh becomes a humming ground of the human activities. Temporary labour tents or huts, crusher machines, movement of trucks and other vehicles all along the length and breadth become …

Talking to Daily Times after inaugurating a cleanliness drive of Leh Nullah at …
Algal neurotoxin enters deep-sea food web, kills whales while crab cakes and marinated clams make for delightful cuisine, shellfish poisoning is a health risk. Shellfish feed on algae that produce harmful toxins. Domoic acid (DA) is one such neurotoxin, dangerously high levels of which are produced during algal blooms of …
President Barack Obama and several state officials on Tuesday announced a renewed effort to clean up the Chesapeake Bay, a once-productive waterway that has seen its crab and oyster populations plunge during decades of failed restoration attempts. Maryland, Virginia and Pennsylvania set tougher targets to reduce the amount of pollutants …

RIVER water is considered polluted when it is altered from the natural state in its physical, chemical and microbiological composition and when its suitability for any safe and beneficial use becomes questionable. The signs of physical water contamination may become obvious through bad taste, offensive odours, unchecked growth of aquatic …
Although persistent drought in West Africa is well documented from the instrumental record and has been primarily attributed to changing Atlantic sea surface temperatures, little is known about the length, severity, and origin of drought before the 20th century. We combined geomorphic, isotopic, and geochemical evidence from the sediments of …
In geochemical studies of water it is a general practice to filter the water samples through a 0.45 ?m membrane. Filtered samples are then acidified with a mineral acid (mostly nitric acid) to a pH < 2, to stabilize various cations. It was observed that if this procedure is not …
Heavy metal (Pb, Cd, Cr, Ni ) concentration in water sediments and fish was analysed from Madivala lake in the month of June 2008. There was an appreciable increase in metal concentrations in going from the water to the sediment samples.The Heavy metal concentration, in water was in the order …
The breach of the Kosi embankment in Nepal in August 2008 marked the failure of conventional ways of controlling floods. After discussing the physical characteristics of the Kosi River and the Kosi barrage project, this paper suggests that the high sediment content of the Kosi River implies a major risk …
Hydro power plants located on the Himalayan rivers, typically, have had to endure high silt content in the water passing through the turbines causing enormous damages to the under-water parts of the turbine. The hydro power generating companies are engaged in mitigating this menance and optimizing generation and profits. The …
The purpose of the new edition is to introduce the basic concepts of water quality and how it is related to ecosystem and human health; and to present an overview and assessments of current and upcoming global water quality issues with examples from around the world. It also includes a …
This report documents a global analysis designed to help illuminate the distribution and condition of oyster reefs, which have been among the most important and valuable resources to humans and among the most poorly understood as a habitat. Numerous recent papers document the condition of and threats to marine ecosystems …
The paper presents an account of the Kusaha breach of the Kosi river which has been widely perceived as a flood event in the media and scientific circles. It is true that a large area was inundated after this event but it is important to appreciate that this inundation was …
Silt has left the Hooghly shallow. Haldia port faces closure Silt deposits at the mouth of the Hooghly river have rendered Haldia port nearly unnavigable, raising fears that India
Usually, the flow of a river is strong enough to flush the sediments into the ocean, according to oceanographer Asok Kumar Bhattacharjee of Calcutta University
Antarctic sediments dating from 30 million to 145 million years ago (a time during which the vast Antarctic ice sheet is thought to have formed and the Transantarctic mountains pushed up) have been a valuable source of information about the forces that changed the climatic conditions of the Antarctic continent. …
