In a significant development on role of hydropower projects in Uttarakhand flood disaster of June 2013, the Expert Body (EB) headed by Dr Ravi Chopra has recommended that at least 23 hydropower projects should be dropped, that hydropower projects played significant role in the Uttarakhand disaster and that there is …
In an historic action that will protect people's health and the environment, and benefit riverfront communities, the U.S. Environmental Protection Agency proposed a plan to remove 4.3 million cubic yards of highly contaminated sediment from the lower eight miles of the Passaic River in New Jersey. The sediment in the …
Models for river avulsions have identified the ratio between down-valley and cross-valley slopes of channels as the triggering factors for the sudden channel shift but have remained untested in the field. The August 2008 avulsion of the Kosi River at Kusaha, 12 km upstream of the Kosi barrage in Nepal, …
Successive state governments in Uttarakhand have pursued economic growth through industrialization without taking into account the fragility of the state’s mountains. A massive rain storm in June 2013 exposed the inherently fragile character of the mountain region. As a battered state began to rehabilitate itself the Supreme Court directed the …

Order of the National Green Tribunal in the matter of Court on its own Motion Vs State of Himachal Pradesh & Others dated 17/09/2013 regarding the condition of the Khajjiar Lake.
New Delhi : Days before Uttarakhand was ravaged by rain, the state government had sought assistance of the National Disaster Management Authority (NDMA) to address the problem of high sediment deposits in its rivers that have raised water levels and could cause flash floods. Faced with the Union Environment and …
The legal geopolitics of the Baglihar and Kishenganga hydroelectric power projects, whose legitimacy under the Indus Waters Treaty has been contested by Pakistan, demonstrates the political nature of technology and the governance of technology need not remain out-of-bounds for non-engineers. In attempting an understanding, this article seeks to step outside …
Geochemical study of a 3.55 m long lake sediment core from the Badanital Lake (Garhwal Himalaya) reveals Late Holocene centennial-scale climatic changes. The ecosystem of the tectonically formed lake seems to be controlled by natural and anthropogenic factors.
Lakes sediments consists of biological and non biological matter accumulated since from formation of the lake. Sediment sequence in lake represents information about the activities within the lake and in its catchment area over a period of time since its inception. Hussain Sagar Lake located in the heart of Twin …
There is a recognized need to anticipate tipping points, or critical transitions, in social–ecological systems. Studies of mathematical and experimental systems have shown that systems may ‘wobble’ before a critical transition. Such early warning signals may be due to the phenomenon of critical slowing down, which causes a system to …
Focusing trans-boundary water regime of Ganges- Brahmaputra- Meghna (GBM) basin, this situation analysis paper discusses the core issues related to environmental security through analyzing various environmental impacts and its significance at the national and regional level. Specifically, the scope of this paper pertains to transboundary water relations between Bangladesh and …
Climate strongly affects the production of sediment from mountain catchments as well as its transport and deposition within adjacent sedimentary basins. However, identifying climatic influences on basin stratigraphy is complicated by nonlinearities, feedback loops, lag times, buffering and convergence among processes within the sediment routeing system. The Palaeocene/Eocene thermal maximum …
This study was performed to elucidate the distribution, concentration trend and possible sources of total mercury (HgT) and methylmercury (MeHg) in sediment cores (<63 μm particle size; n = 75) of Sundarban mangrove wetland, northeastern part of the Bay of Bengal, India. Total mercury was determined by atomic …
Keoladeo National Park (KNP) is an important wintering ground for thousands of birds that undertake a perilous journey over the Himalaya to make a seasonal home in a wetland ecosystem. However, this wetland is now getting polluted by various types of contaminants such as pesticides because of the agricultural practices …
Antimicrobials used in salmon aquaculture pass into the marine environment. This could have negative impacts on marine environmental biodiversity, and on terrestrial animal and human health as a result of selection for bacteria containing antimicrobial resistance genes. We therefore measured the numbers of culturable bacteria and antimicrobial-resistant bacteria in marine …
Flow of the river is its master variable which affects many other variables like water quality, sedimentation, biodiversity, etc. Dams profoundly affect this natural flow. Unfortunately, in India there are very few studies which systematically analyse impacts of a dam on a river and its biodiversity in the pre and …
The purpose of this study is to investigate the current status of metal pollution of the sediments from urban-stream, estuary and Jinzhou Bay of the coastal industrial city, NE China. Forty surface sediment samples from river, estuary and bay and one sediment core from Jinzhou bay were collected and analyzed …
Five watersheds (W1, W2, W3, W4 and W5) in the upper Indus basin were chosen for detailed studies to understand the influences of geomorphology, drainage basin morphometry and vegetation patterns on hydrology. From the morphometric analysis, it is evident that the hydrologic response of these watersheds changes significantly in response …
