Several studies have indicated that glaciers in the Qinghai-Tibet plateau are thinning, resulting in reduced water supplies to major rivers such as the Yangtze, Yellow, Lancang, Indus, Ganges, Brahmaputra in China, and south Asia. Three rivers in the upstream of Yangtze River originate from glaciers around the Geladandong snow mountain group in central Tibet. Here we used elevation observations...

Habitat fragmentation of freshwater ecosystems is increasing rapidly, however the understanding of extinction debt and species decline in riverine habitat fragments lags behind that in other ecosystems. The mighty rivers that drain the Himalaya - the Ganges, Brahmaputra, Indus, Mekong and Yangtze - are amongst the world's most biodiverse freshwater ecosystems. Many hundreds of dams have been co...

Submit Manuscript | http://medcraveonline.com purposes [1]. A large area of the world experiences a huge contamination in groundwater due to mixing of different toxic and minerals and heavy metals either naturally or unorganized development of human civilization [2,3]. The Arsenic is one of the most important and fatal among these minerals. The high concentrations of arsenic (As) in drinking wa...

The flux of total suspended matter (TSM), FTSM, output by several large rivers in Asia, has been decline due to human activities. As the estuary Ganges–Brahmaputra River, Padma River transports a significant amount (SM) Bay Bengal each year. In this study, TSM concentration (CTSM) and FTSM period 1991–2019 were calculated based on data acquired Landsat series satellites an empirical algorithm m...

Snow cover over the Hindu Kush Himalayan (HKH) region is of vital importance for northern Indian water resources. Important North Indian river basins, viz. Indus, Ganges, and Brahmaputra have their headway origin there and rely on the ablation period snow melt. Agriculture, animal husbandry, habitat, and regional socio-economic aspects traditionally depend on the snow cover and winter water sto...

Based on periodical snow cover mapping by NOAA satellites, contributions to runoff from seasonal snow cover, intermittent snowfalls and rain are evaluated in relation to the altitude in the basins of the rivers Ganges (917 444 km) and Brahmaputra (547 346 km) in an altitude range from 0 to 8848 m a.s.l. In spite of insufficient precipitation and temperature data, runoff was simulated with an ac...
