Bedload-to-suspended load ratio and rapid bedrock incision from Himalayan landslide-dam lake record
About 5400 cal yr BP, a large landslide formed a N400-m-tall dam in the upper Marsyandi River, central Nepal. The resulting lacustrine and deltaic deposits stretched N7 km upstream, reaching a thickness of 120 m. C dating of 7 wood fragments reveals that the aggradation and subsequent incision occurred remarkably quickly (∼500 yr). Reconstructed volumes of lacustrine (∼0.16 km) and deltaic (∼0....
متن کاملBankfull Discharge Recurrence Interval in Gravel-bed Rivers
Bankfull discharge was identified in some 30 gravel-bed rivers representing in total c. 40 gauging stations. The catchment sizes vary from 4km2 to nearly 2700km2. Bankfull discharge value increases with basin size. In the case of gravel-bed rivers developed on an impermeable substratum, the following equation emerges: Qb=0·087 A 1·044. Bankfull discharge recurrence interval was determined by fi...
متن کاملMultiscale statistical characterization of migrating bed forms in gravel and sand bed rivers
[1] Migrating bed forms strongly influence hydraulics, transport, and habitat in river environments. Their dynamics are exceedingly complex, making it difficult to predict their geometry and their interaction with sediment transport. Acoustic instrumentation now permits high-resolution observations of bed elevation as well as flow velocity. We present a space-time characterization of bed elevat...
متن کاملA new sampler for extracting bed material sediment from sand and gravel beds in navigable rivers
Grain-size distributions of bed material sediment in large alluvial rivers are required in various scientific and management applications, but characterizing gravel beds in navigable rivers is hampered by difficulties in sediment extraction. The newly developed and preliminarily tested sampler reported here can extract sediment from a range of riverbeds. The 36 × 23 × 28 cm stainless steel toot...
متن کاملVariation in the reference Shields stress for bed load transport in gravel-bed streams and rivers
[1] The present study examines variations in the reference shear stress for bed load transport (tr) using coupled measurements of flow and bed load transport in 45 gravel-bed streams and rivers. The study streams encompass a wide range in bank-full discharge (1–2600 m/s), average channel gradient (0.0003–0.05), and median surface grain size (0.027–0.21 m). A bed load transport relation was form...
