ABSTRACT River systems of part the Himalayan foreland, northern Bihar plains, India, are described in terms their channel morphology, hydrology and suspended sediment characteristics. A simple classification river based mainly on source area characteristics is proposed: (i) mountain‐fed, (ii) foothills‐fed, (iii) plains‐fed (iv) mixed‐fed rivers. Distinct differences noted between these classes systems. Most rivers show evidence movement, by avulsion, but cut‐offs also occur locally. The...
Discontinuity-bounded late Quaternary sequences in the southern Gangetic Plains (Himalayan Foreland Basin) reflect floodplain aggradation and degradation response to forcing by powerful Southwest Indian Monsoon. The major Himalayan cratonic rivers this area occupy narrow, incised valleys do not inundate adjoining broad interfluves, which display soil development, small plains-fed rivers, lakes, eolian deposits, badland ravines. However, these areas formerly experienced active alluviation...
Abstract Modifications to standard definitions of braiding and meandering are proposed indicate the morphology every river channel reach quantitatively, whether it has single or multiple channels. Sinuosity ( P ) is defined as, = L cmax / R , where length midline (in single-channel rivers), widest multi-channel overall reach. Braiding a measure multiplicity new term ‘braid-channel ratio’ B been ctot total mid-channel lengths all channels in Another expression for braid-channel ratio which...
The potential impacts of climate change and socio-economic on flow water quality in rivers worldwide is a key area interest.
Rapid groundwater depletion from the northwestern Indian aquifer system in western Indo-Gangetic basin has raised serious concerns over sustainability of and livelihoods that depend on it. Sustainable management this requires we understand sources rates recharge, however, both these parameters are poorly constrained region. Here analyse isotopic (δ18O, δ2H tritium) compositions groundwater, precipitation, river canal water to identify recharge sources, zones flow Ghaggar River basin, which...
Abstract Urbanism in the Bronze-age Indus Civilisation (~4.6–3.9 thousand years before present, ka) has been linked to water resources provided by large Himalayan river systems, although largest concentrations of urban-scale settlements are located far from extant rivers. Here we analyse sedimentary architecture, chronology and provenance a major palaeochannel associated with many these settlements. We show that is former course Sutlej River, third present-day Using optically stimulated...
Abstract. High soil erosion and excessive sediment load are serious problems in several Himalayan river basins. To apply mitigation procedures, precise estimation of yield with associated uncertainties needed. Here, the revised universal loss equation (RUSLE) delivery ratio (SDR) equations used to estimate spatial pattern (SE) (SY) Garra River basin, a small tributary Ganga. A methodology is proposed for quantifying propagating SE, SDR SY estimates. Expressions uncertainty propagation...
This study investigates the potential impacts of future climate and socio-economic change on flow nitrogen fluxes Ganga river system.
Hydrological and sediment transport characteristics for the Kosi basin, which covers parts of Nepal India, were analysed to understand spatiotemporal variability hydrology dynamics basin its implications flood hazard dynamics. The study revealed that ∼56% discharge at Chatara (where all major tributaries meet) is contributed from western part even though this constitutes only 34% total area. In contrast, central eastern constitute 57% 8% area but contribute ∼38% ∼16% Chatara, respectively....
Sediment connectivity, defined as the degree of linkage between sediment sources to downstream areas, is one most important properties that control landscape evolution in river basins. The linkages amongst different parts a catchment depends mainly on hinterland characteristics (e.g. morphology, slope, shape, relief, and elevation), channel stream network density, valley confinement), combined effects vegetation land use changes abandonment). This paper evaluates connectivity upper Kosi...
Northwestern India has been identified as a significant hotspot of groundwater depletion, with major implications for sustainability caused by excessive abstraction. We know relatively little about the detailed spatial and temporal changes in storage this region, nor do we understand interplay factors controlling these changes. Groundwater managers policymakers require such information to monitor development make strategic decisions sustainable management groundwater. Here, characterise...
