The end of the world is coming – but not for a while yet. That’s according to a new study indicating that we have 1.75 billion years left until Mother Earth gives up the ghost.

Dams are being built in different sizes depending on the requirements and the height permissible at the particular site. The higher a dam, the larger the concerns for undesirable impacts that have to be mitigated and the assurance that has to be given to everyone that the dam is not a time bomb, the unfortunate sentiment that many tend to possess. Dams have multi-directional benefits that are much larger than the visible damage that it creates.

Heavy rainfall has wreaked havoc on the region because of the fragile nature of the Himalayan range and poor soil stability in its steep slopes. But it is mand-made factors that have compounded the scale of the disaster. Read this special report by Down To Earth.

An important challenge in geomorphology is the reconciliation of the high fluvial incision rates observed in tectonically active mountain ranges with the long-term preservation of significant mountain-range relief in ancient, tectonically inactive orogenic belts. River bedrock erosion and sediment transport are widely recognized to be the principal controls on the lifespan of mountain ranges. But the factors controlling the rate of erosion and the reasons why they seem to vary significantly as a function of tectonic activity remain controversial.

Sixty hot springs are spread over 18 regions in the west coast of Maharashtra, India. The area is covered by Deccan Basalts. Periodic water sampling was done for more than 5 years from Tural and Rajvadi hot springs along with waters from other deep wells for hydrochemical and isotopic analyses to study the relation between seismicity and hydrochemistry. Residence time of hot spring waters was estimated using the 14C dating.

The present study investigates and analyses the behavior of a concrete gravity dam during the strong ground horizontal motions due to an earthquake with CADAM. The model in thesis is the structure of Hirakud gravity dam. Hirakud dam across river Mahanadi in eastern India is a composite structure of earth, concrete and masonry.

GUWAHATI, Aug 27 – The National Hydro Electric Power Corporation (NHPC) which today had a discussion with the Krishak Mukti Sangram Samiti (KMSS) and the Asom Jatiyatabadi Yuba Chatra Parishad (AJY

An angry protest is gathering momentum in Mithi Virdi, a picturesque village in Gujarat’s Bhavnagar district. Four villages have united forces to oppose a nuclear plant coming up in their vicinity. Mithi Virdi is likely to become as famous as Jaitapur and Kudankulam. In 2008, Mithi Virdi was placed on India’s nuclear map when the Indo-US deal was signed. The Nuclear Power Corporation of India Limited (NPCIL) endorsed a Memoradum of Understanding (MoU) with Westinghouse, a nuclear major in Pennsylvania, to build a power plant on land acquired from four villages here.

The debate surrounding the safety of shale gas development in the Appalachian Basin has generated increased awareness of drinking water quality in rural communities. Concerns include the potential for migration of stray gas, metal-rich formation brines, and hydraulic fracturing and/or flowback fluids to drinking water aquifers. A critical question common to these environmental risks is the hydraulic connectivity between the shale gas formations and the overlying shallow drinking water aquifers.

Shale gas can be a powerful tool in combating climate change. However, its exploitation may also lead to undesired environmental effects that can conversely worsen climate change.
