Abstract Bedload transport is an important factor to describe the hydromorphological processes of fluvial systems. However, conventional bedload sampling methods have large uncertainty, making it harder understand this notoriously complex phenomenon. In study, a novel, image-based approach, Video-based Tracker (VBT), implemented quantify gravel by combining two different techniques: Statistical...

[1] Observations of likely fluvial channels on the surface of Titan, along with Titan’s geologically youthful surface, motivate this study of comparative fluvial erosion rates on Titan and the Earth. The roles of bedload abrasion, suspended load abrasion, plucking, and cavitation are considered. Despite orders of magnitude differences in some of the physical parameters that control fluvial inci...

In this study, we map different types of channel geomorphic units in a sediment-starved, residual-flow reach before and after an artificial flood. Bedload particles previous sediment augmentation measure are tracked with passive integrated transponder tags, water depth flow velocity recorded across ten cross-sections. The analysis focuses on the influence bedload transport river morphology. Our...

Natural fluctuations of bedload transport under steady hydraulic conditions have been often attributed to the propagation sediment pulses in river channels, leading hysteretic patterns rating curves at both hydrograph and seasonal timescales. However, direct field observations pulse effect on rates rarely reported. Two datasets recorded a small Mediterranean badland catchment Southern French Pr...
