River dams provide many benefits, including flood control. However, due to constantly
evolving channel morphology, downstream conveyance of floodwaters following dam …

The amount of transported sediment load by streams is a vital but high nonlinear dynamic
process in water resources management. In the current paper, two optimum predictive …

Dunes form critical agents of bedload transport in all of the world's big rivers, and constitute
appreciable sources of bed roughness and flow resistance. Dunes also generate …

At a global scale, delta morphologies are subject to rapid change as a result of direct and
indirect effects of human activity. This jeopardizes the ecosystem services of deltas …

River bars are macroscale sediment patterns, whose main geometrical features (wavelength
and amplitude) depend on the mutual interactions between hydrodynamics and sediment …

Bedload is notoriously challenging to measure and model; its dynamics, therefore, remains
largely unknown in most fluvial systems worldwide. We present results from a global scale …

The impacts of aquatic vegetation on bed load transport rate and bedform characteristics
were quantified using flume measurements with model emergent vegetation. First, a model …

River delta-front estuaries (DEs) are vital interfaces for fluxes between terrestrial and marine
environments. However, deep uncertainty exists in estimating the sedimentary pollutant flux …

Abstract The Active Yellow River (Huanghe) Delta (AYRD) is a complex landform in which
rapid deposition takes place due to its geologic formation and evolution. Continuous …

Dune dimensions in sand‐bedded rivers are often thought to scale with flow depth (h), with
height (H) scaling as 1/6h and length (L) as 5h, even though substantial scatter about the …
