The Sethusamudram Ship Canal Project (SSCP) is a 167 km long shipping canal, and envisages the creation of a navigable canal from the Gulf of Mannar to the Bay of Bengal to facilitate the movement of ships. The proposed SSCP site is located in a globally significant marine ecosystem – …
ON September 22, around 50,000 people gathered at Kharo Chaan, 150 km southeast of Karachi in Pakistan, for quite an unprecedented festival: the Jashn-e-Indus Delta. Politicians and experts paid tributes to the river Indus, diyas (earthen lamps) were floated, a fair number of young men and women even danced in …
The Upper Tana River Basin is one of Kenya's most important natural resource bases. Its Masinga Reservoir supplies water and hydroelectric power for 65 percent of the nation. Unregulated deforestation and expansion of cultivation practices onto marginal soils has resulted in significant reservoir siltation, reduced ecosystem function, and more erratic …
The large agrarian population of West Bengal drink groundwater with arsenic content anywhere between 0.05 and 3.7 mg/L. Greater than 44% of this population suffers from arsenic related diseases like conjunctivitis, melanosis, hyperkeratosis, and hyper pigmentation. In certain areas gangrene in the limb, malignant neoplasm and even skin cancer have …
Any reduction in water spread area at a specified elevation over a time period is indicative of sediment deposition at this level. This when integrated over a range of water stages helps in computing volume of storage lost through sedimentation. This study relates to estimation of capacity loss due to …
More than 131 x 106 metric tons (MT) of inorganic sediments accumulated in coastal wetlands when Hurricanes Katrina and Rita crossed the Louisiana coast in 2005, plus another 281 x 106 MT when accumulation was prorated for open water area. The annualized combined amount of inorganic sediments per hurricane equals …
Heavy rains lashed parts of Maharashtra and Gujarat reminding people of last year's deluge. The rains were caused by low pressure in the Bay of Bengal. This intensified into a deep depression, causing torrential rains in Andhra Pradesh, Orissa and Madhya Pradesh. Gujarat and Maharashtra suffered flooding. Karnataka and Madhya …
The present paper reviews recent developments in methodology for valuing the role of wetlands in supporting economic activity. The study brings out several issues related to conservation and management of the Pong Dam wetland. For the protection of aquatic biodiversity of the wetland, integrated management plans are required. The main …
The present paper is an analysis of the scheme for the interlinking of rivers on a National Water Grid that would transfer water from one basin to another, from a water source having surplus water to areas with scarce water resources. The idea of interlinking two of the great river …
Secondary data as well as the monsoon study presented in this report confirm that not only has the sediment load in the Bhadra River dramatically increased as a result of the mining, but also that a very small fraction of the watershed area, comprising the KIOCL mining site, is by …
This document is intended to provide an overview of the major components of surface and ground water quality and how these relate to ecosystem and human health. Local, regional, and global assessments of water quality monitoring data are used to illustrate key features of aquatic environments, and to demonstrate how …
The rivers draining the Gangetic plains exhibit remarkable geomorphic diversity, and this has consequently characterized the rivers to be dominantly aggradational in the Eastern Gangetic Plains (EGP) and degradational in the Western Gangetic Plains. We suggest that steam power and sediment supply are the two main fluvial parameters which govern …
Renuka lake, named after the Goddess Renuka ji, the mother of Lord Parashuram, is situated near Dadahu in Sirmour district of Himachal Pradesh. Since years, it has been receiving silt and debris from 22 nallas, which are all around the catchment of the lake, which is causing ecological deterioration, habitat …
The ability of many introduced fish species to thrive in degraded aquatic habitats and their potential to impact on aquatic ecosystem structure and function suggest that introduced fish may represent both a symptom and a cause of decline in river health and the integrity of native aquatic communities. The varying …
large-scale construction of dams is preventing sedimentation in delta regions, in turn making it easier for the sea to advance and encroach on pristine ecosystems. This is what researchers at the Andhra University, Visakhapatanam, have found. The most devastating outcomes of this phenomenon are displacement of coastal communities and destruction …
Sethusamudram Shipping Canal Project, when completed, will transform parts of the southern coromandal coast qualitatively. Since historical times, this portion of the coast (Palk Bay, Adam’s Bridge) is used only to fleets of small crafts involved in coastal trading and fishing. Sethu Canal will transform this into a coast that …
Analysis of multi-date satellite sensor data and maps indicated loss of 1836 ha of land during 1976–2001 along the Godavari deltaic coast resulting in displacement of coastal communities and mangrove destruction. Decrease in sediment loads from an annual average of 145.26 million tons in 1971–79 to 56.76 million tons during …
Hydrological characteristics and sedimentation loading in Hokersar wetland of Kashmir Himalaya was monitored from November 2000 to october 2001. The compound water budget showed a substantial (91 percent) input from various surface inflows and just 9 per cent through precipitation. Major water discharge (67 per cent) occurs through surface outlets, …
