Order of the National Green Tribunal in the matter of Residents Welfare Association Savita Vihar Vs Irrigation & Flood Control Department & Others dated 28/05/2025. The applicant raised the grievance against throwing of construction debris and sewage obstruction in the Ghazipur drain. According to the applicant this drain flows behind …
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 …
California has experienced a dry 21st century capped by severe drought from 2012 through 2015 prompting questions about hydroclimatic sensitivity to anthropogenic climate change and implications for the future. We address these questions using a Holocene lake sediment record of hydrologic change from the Sierra Nevada Mountains coupled with marine …
Judgement of the National Green Tribunal (Western Zone Bench, Pune) in the matter of Old Cross Fishing Canoe Owners Co-op Society Ltd. & Others Vs Mormugao Port Trust & Others dated 02/09/2016 regarding Environmental Clearance (EC), dated 9th February, 2016, granted for the capital dredging activity to Mormugoa Port Trust …
Earth's surface gained 115,000 km2 of water and 173,000 km2 of land over the past 30 years, including 20,135 km2 of water and 33,700 km2 of land in coastal areas. Here, we analyse the gains and losses through the Deltares Aqua Monitor — an open tool that detects land and …
Judgement of the National Green Tribunal in the matter of Srinagar Bandh Aapda Sangharsh Samiti & Others Vs Alaknanda Hydro Power Co. Ltd & Others dated 19/08/2016 asking Alaknanda Hydro Power Co. Ltd. to pay compensation for the damage suffered by the members of the Srinagar Bandh Aapda Sangharsh Samiti …
Information on sediment concentration in rivers is important for design of reservoirs and for environmental applications. Because of the scarcity of continuous sediment data, methods have been developed to predict sediment loads based on few discontinuous measurements. Traditionally, loads are being predicted using rating curves that relate sediment load to …
Integrated Hydrological Data Book is a compendium of important information of major basins consolidated at the national level. The present issue of the data book provides updated basin/sitewise data of all non-classified basins covering aspects such as location, drainage area, temperature, average runoff, sesonal water flow, historical water levels, average …
The phenomenon of low dissolved oxygen (known as hypoxia) in coastal ocean system is closely related to a combination of anthropogenic and natural factors. Marine hypoxic occurs in the Yangtze Estuary, China with high frequency and long persistence. It’s known that it related primarily to organic and nutrient enrichment influenced …
Traditional risk assessment and source apportionment of sediments based on bulk polycyclic aromatic hydrocarbons (PAHs) can introduce biases due to unknown aging effects in various sediments. We used a mild solvent (hydroxypropyl-β-cyclodextrin) to extract the bioavailable fraction of PAHs (a-PAHs) from sediment samples collected in Pearl River, southern China. We …
The rise of plastics since the mid-20th century, both as a material element of modern life and as a growing environmental pollutant, has been widely described. Their distribution in both the terrestrial and marine realms suggests that they are a key geological indicator of the Anthropocene, as a distinctive stratal …
A time series of organic carbon export from Gulf of Maine (GoM) watersheds was compared to a time series of biological, chemical, bio-optical, and hydrographic properties, measured across the GoM between Yarmouth, NS, Canada, and Portland, ME, U.S. Optical proxies were used to quantify the dissolved organic carbon (DOC) and …
As most port areas throughout the world, Guanabara Bay (GB), which hosts the Harbour of Rio de Janeiro (HRJ), is under intense environmental stress. Located in one of the most iconic places of the world, GB environmental status has been the focus of worldwide attention with the imminent 2016 Olympic …
Order of the National Green Tribunal in the matter of Madan Lal Vs. Union of India & Ors. regarding the illegal dumping of huge quantities of muck by the Project Proponent in river Satluj. NGT directed a committee of officers from the Pollution Control Board Himachal Pradesh and officers from …
The past was a world of giants, with abundant whales in the sea and large animals roaming the land. However, that world came to an end following massive late-Quaternary megafauna extinctions on land and widespread population reductions in great whale populations over the past few centuries. These losses are likely …
The Bahía Blanca Estuary, located at the Atlantic coast of Argentina, includes a governmental nature reserve to protect biodiversity, lands and water; however, as the process of industrialization and urbanization is stepping rapidly at the neighbouring area, the potential increase in contaminant loads is a serious concern. After several contaminants …
Pollen analysis of 1.75 m deep sediment core from Tula-Jalda (Amarkantak) in Anuppur district, Madhya Pradesh shows that around 4500–3600 cal years BP, this region supported open mixed tropical deciduous forests comprising chiefly Madhuca indica followed by Terminalia, Mitragyna parvifolia, Haldina cordifolia, Emblica officinalis and Acacia, under a warm and …
The deep ocean was once assumed to be lifeless and barren. Today we know that even the deepest waters teem with living creatures, some of them thought to be little changed from when life itself first appeared on the planet. The deep ocean is also essential to the earth’s biosphere—it …
Forty years after the ocean floor was first mapped by hand, a team of Australian researchers has created the first digital map of the entire sea floor. Made by the University of Sydney's School of Geosciences and National ICT Australia (NICTA), the map can be used to plot the planet's …
Knowing the patterns of distribution of sediments in the global ocean is critical for understanding biogeochemical cycles and how deep-sea deposits respond to environmental change at the sea surface. We present the first digital map of seafloor lithologies based on descriptions of nearly 14,500 samples from original cruise reports, interpolated …
The Bengal Basin evolved as a rift-controlled extensional basin along the NNE–SSW trending Basin Margin Fault coevally with the 85 East Ridge in the Bay of Bengal during the short-lived hotspot activity south of Bhubaneswar. The basin opening post-dated the Kereguelen Plume magmatism (at ~116 Ma), but predated the phase …
