Particle size characteristics of suspended sediment transported in meltwater from the Gangotri Glacier, central Himalaya — An indicator of subglacial sediment evacuation

摘要: Abstract Proglacial meltwater streams draining out of the Himalayan glaciers carry considerable amounts suspended sediment, with a variety particle sizes, because supraglacial, englacial, and subglacial debris, as well formation sediments from erosion by movement ice. This paper examines size transported in proglacial stream Gangotri Glacier for seven consecutive melt seasons (May–October, 2000–2006) order to provide information on (i) temporal variations distribution, (ii) texture mineralogy sediments, (iii) origin evacuation pattern sediments. Our results indicate dominance silt (0.002–0.06 mm) particles (71%) followed sand (0.06–0.6 mm) (24%) clay (
