Judgment of the National Green Tribunal, May 27, 2025 in the matter of Sumit Saini Vs Shree Ram Steel Industries & Others. Sumit Saini, resident of village Damla, District Yamuna Nagar, Haryana had sent a letter petition dated May 14, 2022 to the NGT. The application said that around 25 …
Thermo-erosion gullies in continuous permafrost regions where ice-wedge polygons are widespread contribute and change the drainage of periglacial landscapes. Gullying processes are causing long-term impacts to the Arctic landscape such as drainage network restructuring, permafrost erosion, sediment transport. Between 2009 and 2013, 35 gullies were mapped in a polygon terrace …
Phosphorus (P) is one of the most important limiting nutrients for the growth of oceanic phytoplankton and terrestrial ecosystems, which in turn contributes to CO2 sequestration. The solid-phase speciation of P will influence its solubility and hence its availability to such ecosystems. This study reports on the results of X-ray …
The swampy intertidal zone and part of the backshore of Henry's Island coast of 1969 have now been submerged. Topographic surveys, analysis of textural and palynological character of sediments coupled with time-series analyais of shoreline change show phasewise erosion. This has resulted in ingression of sea. Modern sand, transported from …
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 …
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 …
The days when the gigantic Indian rivers — the Ganges, Indus and Brahmaputra — roar freely down the steep slopes of the Himalayas may be numbered. Roughly 300 dams are proposed or under construction in the deeply cut valleys of India’s mountainous north, part of a massive effort to meet …
A numerical model of salt marsh evolution shows that competition between mineral sediment deposition and organic matter accumulation determines the net impact of climate change on carbon accumulation in intertidal wetlands.
Small hydropower (SHP) being most reliable and environmentally benign energy technology or electricity generation plays an important role in development of a region/nation. Major portion of hydropower potential in India lies in Himalayan region.
Atmospheric carbon dioxide concentrations and climate are regulated on geological timescales by the balance between carbon input from volcanic and metamorphic outgassing and its removal by weathering feedbacks; these feedbacks involve the erosion of silicate rocks and organic-carbon-bearing rocks. The integrated effect of these processes is reflected in the calcium …
For long, widely divergent views (based on isolated pieces of historical evidence or broad geological evolution of the subcontinent, notably the rise of the Himalayas in mid-late Miocene), had prevailed regarding origin and antiquity of the Thar Desert. Studies of the past few decades have since provided a wealth of …
p { margin-bottom: 0.08in; } It is being called a spectacular success - but also a lost opportunity. With floodwaters rising to record levels along the Lower Mississippi river, the system of levees and spillways that protect the low-lying cities of Baton Rouge and New Orleans faced an unprecedented test. …

Coastal zone is very dynamic, being the meeting place of land and sea water. The development in coastal area and subsequent population growth have given rise to problems such as erosion, sedimentation, saltwater intrusion, degradation of natural resources etc. Satellite data has proved to be more appropriate for change detections …
Watershed response to produce runoff by a rainfall event depends upon the watershed characteristic and each watershed has its exclusive characteristics. However, most of the watersheds lacks in the facility of recording runoff, in such a case, morphometric parameters of a watershed are valuable information to evaluate watershed capacity to …
Why is the river so notorious? Assam has lost about 170,000 hectares to the Brahmaputra and its major tributaries between 1990 and 2007. These are mostly prime land such as tea gardens and the economic loss is phenomenal. The problem is the Brahmaputra transports heavy sediment load—about 800 million tonnes …
Could the devastation caused by hurricanes Katrina and Rita have had a silver lining? The sediment washed into New Orleans by the floods accompanying the storms may have blanketed over heavily polluted, lead-laden soil in the city, leading to a decrease in lead levels in the bloodstreams of children across …
Increased erosion associated with the rise of the world's great mountain ranges has been held to be the cause of a prolonged episode of past climate cooling. That connection is now brought into doubt.
Police unearthed illegal transportation of sand in water tank at Railway station on Monday. According to police, 53 barrels of sands were seized. Each tank had 50 kg sand. The sand was booked for transport through Southern Railway Parcel Booking Agency in the name of chemicals. However, there was no …
The District administration has been empowered to curb illegal sand mining and transportation in Chikkaballapur ,'District In-charge Minister Dr Mumtaz Ali Khan has said. Speaking at the meeting of Task Force on Prevention of Illegal Sand Mining and Transportation at Deputy Commissioner
Kakinada, April 4: Over 300 persons in Seelamvaripalem and Sriramapuram of U. Kottapalli mandal and leaders and activists of the Telugu Desam party staged a protest on Sunday against the illegal transportation of sand by some people with the help of Congress leaders at sand reaches which come under the …
