Etched into the memory of Asraf Ali, was the day in 1987 when the banks of the mighty river Brahmaputra overflowed and washed away the family home. Only 13 years old at the time, he lost both his parents, and their small piece of land to severe flooding in the municipality of Gaibandha, in Bangladesh. He remained homeless until he moved to the centre of Gaibandha to seek work as a pushcart driv...

Abstract. Following the 130 ± 5 × 106 m3 detachment of Sedongpu Glacier, south-eastern Tibet, in October 2018, Valley, which drains into Yarlung Tsangpo (Brahmaputra) River, underwent rapid large-volume landscape changes. Between December 2018 and 2022 particular during summer 2021, an enormous volume total ∼ 335 was eroded from former glacier bed, forming a new canyon up to 300 m depth, 1 km w...

Rivers act as temporary sinks of microplastics and a key medium allowing to enter the ocean. In this study, pollution in river shore sediment Indian Himalaya, including Brahmaputra River Indus was discussed. Sampling campaigns were performed years 2018 2019. Sample pretreatment using Na 2 WO 4 ·2H O for density separation H oxidation organic material. Microplastics analysis by FTIR microscope. ...

The purpose of this study is to evaluate the progress and regional variations of crop production in Bangladesh. The secondary data were used and collected for the years 1980-81 to 2002-03 from the ‘Statistical Yearbooks of Bangladesh’, ‘Yearbook of Agricultural Statistics’ and population census of different years. The study was conducted during the period from September 2006 to February 2008. A...

Alluvial fans are constructed when river deposition raises local elevations until the “avulses” to an alternative lower elevation alignment. Avulsions may be triggered by exogenous events, such as floods that locally overtop river’s banks; they then cause extreme flooding on a fan and have major impacts. Rivers draining Himalayas into Gangetic plain behaved historically in this way; for example...

Sixty-eight groundwater samples from the Ganges-Brahmaputra floodplain in the Bengal Basin were analyzed to assess the groundwater geochemistry, the subsurface hydrology, the buffering effects of sediments on trace metal concentrations and their isotopic compositions, and the magnitude of the subsurface trace element flux to the Bay of Bengal and to the global ocean. Samples obtained from depth...
