Floods of high magnitude are one of the major problems in the north-eastern region of India. Heavy flooding causes abrupt changes in the flow pattern of the rivers. The present paper deals with the study of three northern bank tributaries of the Brahmaputra river, namely Jia-Bhareli, Puthimari and Pagladiya. The river Brahmaputra shows significant amount of erosion and deposition in the basin. ...

In order for the Indian government to maximize Integrated Water Resource Management (IWRM), the Brahmaputra River has played an important role in the undertaking of the Pilot Basin Study (PBS) due to the Brahmaputra River’s annual regional flooding. The selected Kulsi River—a part of Brahmaputra sub-basin—experienced severe floods in 2007 and 2008. In this study, the Rainfall-Runoff-Inundation ...

This paper describes a fully automated scheme that has provided calibrated 1–10-day ensemble river discharge forecasts and predictions of severe flooding of the Brahmaputra and Ganges Rivers as they flow into Bangladesh; it has been operational since 2003. The Bangladesh forecasting problem poses unique challenges because of the frequent life-threatening flooding of the country and because of t...

Glacier distribution and glacier changes were investigated in the Upper Brahmaputra River Basin using remote sensing and GIS in order to determine the influence of melting glaciers on the long-term runoff of the Brahmaputra River (EU-project BRAHMATINN). Current glacier distribution and glacier changes since the 1970/80s were mapped using multi-temporal optical remote sensing data from the Land...

Introduction to the problem complexity The natural water mostly used in the South Asian region comes from the Ganges– Brahmaputra–Meghna (GBM)1 river basin. The four South Asian countries Bangladesh, Nepal, India and Bhutan are sharing the largest river basin of the world together. China is also part of this GBM delta, nevertheless, it only shares the Brahmaputra along with Bhutan, India and Ba...

The rivers from the Himalaya supply large quantities of particulate and dissolved materials to the oceans. Among the various rivers, the Brahmaputra ranks highest in contributing to the sediment budget of the Bay of Bengal. The erosion rates among the sub-basins of the Brahmaputra vary over 1–2 orders of magnitude, the highest being in the Eastern Syntaxis basin which is eroding at an enormousl...

Surface water storage is a key component of the terrestrial hydrological and biogeochemical cycles that also plays a major role in water resources management. In this study, surface water storage (SWS) variations are estimated at monthly time-scale over 15 years (1993–2007) using a hypsographic approach based on the combination of topographic information from Advance Spaceborne Thermal Emission...

The Sr isotopic composition of rivers and groundwaters in the Bengal Plain is a major contributor to global oceanic inventory. stable strontium isotope ratios (? 88 Sr) provide new tool identify chemical weathering reactions terrestrial water. In this study, we investigated spatiotemporal variations ? samples river water, bedload sediment, groundwater collected from Ganges–Brahmaputra–Meghna dr...

The study has been carried out to assess surface water quality of Old Brahmaputra River from September 2015 to March 2016. DO, BOD5, COD, pH, EC, Chloride, Alkalinity, and Hardness concentrations in water samples have been found to range within 0.66-2.9 mg/L, 21-138 mg/L, 45-250 mg/L, 7.1-7.8, 185-1080 uS/cm, 10-98 mg/L, 85-197 mg/L, and 84-148 mg/L, respectively. Multivariate statistical analy...
