Huge voluminous debris supplies that are transported because of the extreme rainfall events and glacial lake outburst floods has resulted in the accumulation of excessive sediments, thereby depleting the capacities of desilting chambers in the downstream hydropower projects. Therefore, the present article is focused on understanding the textural facies, bulk mineralogical composition, and environmental magnetic properties of suspended sediments to highlight the transport characteristics within the Chorabari glacierized catchment. Sediment representatives were analyzed by the X-Ray diffraction (XRD) and routine mineral magnetic parameters for the ablation seasons (June-September) of 2009, 2011, and 2012. Results reveal that monthly and seasonal fluctuations in the runoff magnitude exhibit significant influence on the linked-conduit system resulting in the enlargement of transport pathways. Flemming's (sand/silt/clay) trigon reflects the dominance of silty sand facies with little clay content implying that the influence of hydrometeorological conditions transport the glacial debris to the downstream areas. Proglacial meltwater stream transported more than 60% of the total weight percentages of hard mineral aggregates such as quartz and feldspar fractions indicating high intensity of physical disaggregation that occurs at the high-altitude environment. Environmental magnetic properties reflect unimodal source showing combined signatures of weak ferrimagnetic and high nonmagnetic minerals. Analysis of Pearson correlation coefficient (PCC) revealed heterogeneity in the production and transportation of silt-and sand-sized sediments for each ablation season. These findings conclude that considerable percentages of fine glacial debris gets entrained into the linked-conduits from where they get exported as suspended sediments along with glacier meltwater through the subglacial opening.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
