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 …
The Bhagirathi Valley is investigated to understand the impact of various barrages and dams on natural river flow. The multiple barrages and dams in the valley (downstream of the Bhatwari Village) have obstructed/disrupted natural flow of the river which has adversely impacted geomorphological and ecological functions of the river. Besides, …
Interim report on deposition of river bed material for Ganga river and its tributaries in the matter of Vijay Verma Vs Uttarakhand Forest Development Corporation & Others filed before NGT, 19/11/2018. National Green Tribunal had restrained mining activity on seven river viz. Bishanpur, Bhogpur, Chidiyapur, Kotwali, Rawasan I, Rawasan II …
With the growing recognition that effective action on climate change will require a combination of emissions reductions and carbon sequestration, protecting, enhancing and restoring natural carbon sinks have become political priorities. Mangrove forests are considered some of the most carbon-dense ecosystems in the world with most of the carbon stored …
Bed sediment samples were collected along the 9.5 km long inlet channel of Chilika lagoon, east coast of India during low freshwater discharge and low rainfall condition. Distributions of bed sediment along with its texture were studied in detail. Bivariate plots between mean, sorting, skewness and kurtosis of sediments revealed …
Increased energy demand has led to plans for building many new dams in the western Amazon, mostly in the Andean region. Historical data and mechanistic scenarios are used to examine potential impacts above and below six of the largest dams planned for the region, including reductions in downstream sediment and …
Egypt’s Nile delta, only ~1 m above mean sea level at the Mediterranean coast, is subject to uneven rates of submergence. This is a response to several factors leading to increasing land lowering (subsidence) of the northern delta and adjacent seafloor, plus an accelerating rise in eustatic (world) sea level …
Debris flows often cause devastating damage to property and can injure or kill residents in mountainous areas. The construction of check dams in debris-flow valleys is considered a useful strategy for mitigating the damages downstream. In this paper, a new type of spillway structure with lateral contraction was proposed to …
The world’s rivers deliver 19 billion tonnes of sediment to the coastal zone annually1, with a considerable fraction being sequestered in large deltas, home to over 500 million people. Most (more than 70 per cent) large deltas are under threat from a combination of rising sea levels, ground surface subsidence …
Economic development relies critically on infrastructure development. Yet, without careful planning, the services provided by hydropower facilities and dams are at risk. Ensuring the long-term resilience of these critical infrastructure facilities requires early and consistent attention to the processes of reservoir sedimentation, which reduce the storage capacity of reservoirs and …
The effects of climate change and variability on river flows have been widely studied. However the impacts of such changes on sediment transport have received comparatively little attention. In part this is because modelling sediment production and transport processes introduces additional uncertainty, but it also results from the fact that, …
Deltas around the globe are facing a multitude of intensifying environmental change and development-linked pressures. One key concern is the reduction in the quantity of suspended sediment reaching and building floodplains. Sediment deposition provides multiple services to deltaic social-ecological systems, in particular, countering the subsidence of the delta-body, and providing …
River health assessment (RHA) protocols are the tools used globally that emphasize upon factors which contribute for ecological fitness of the river such as catchment health, floodplain health, channel health, flow health, quality health and biotic health indicators. Human intervention by constructions of dams, excess water abstraction, channel diversion and …
Corporations and other multinational institutions are increasingly looking to evaluate their innovation and procurement decisions over a range of environmental criteria, including impacts on ecosystem services according to the spatial configuration of activities on the landscape. We have developed a spatially explicit approach and modeled a hypothetical corporate supply chain …
To promote sustainable sand extraction, these guidelines released by the Union ministry of environment and forests lays emphasis on monitoring of the mined out material, which is key to the success of environment management plan. It has suggested tapping “alternative sources of sand and gravel”. The main objectives of the …
Glacial erosion is fundamental to our understanding of the role of Cenozoic-era climate change in the development of topography worldwide, yet the factors that control the rate of erosion by ice remain poorly understood. In many tectonically active mountain ranges, glaciers have been inferred to be highly erosive, and conditions …
This guideline provides criteria for sustainable sand mining both in-stream and off-channel extraction of sand, the theory of sediment transport in rivers, an important factors determining sand replenishment rate together with a discussion of the impacts of river sand mining. Recommendations for management of sustainable sand extraction are the key …
Measurements of sediments eroded by the Mackenzie River reveal the widespread export of permafrost-derived biospheric carbon that is several thousand years old, and demonstrate its burial in the Arctic Ocean, suggesting that high-latitude rivers can act as important carbon dioxide sinks.
The Ganges–Brahmaputra river delta, with 170 million people and a vast, low-lying coastal plain, is perceived to be at great risk of increased flooding and submergence from sea-level rise. However, human alteration of the landscape can create similar risks to sea-level rise. Here, we report that islands in southwest Bangladesh, …
Majuli, one of the largest inhabited river islands in the world, is under serious threat due to large-scale bank erosion by the Brahmaputra River. There is urgent need to preserve this socio-culturally rich island of over 0.2 million people. Erosions have been shrinking its landmass significantly and thereby causing enormous …
