DOI: 10.1002/esp.4186
Abstract: Bulle-Effect is a phenomenon in which a disproportionately higher amount of near-bed sediment load at a fluvial diversion moves into the diverted channel, even for cases in which the proportion of water (with respect to… read more here.

DOI: 10.1002/esp.4260
Abstract: The permeability of river beds is an important control on hyporheic flow and the movement of fine sediment and solutes into and out of the bed. However, relatively little is known about the effect of… read more here.

DOI: 10.1016/j.jher.2018.01.001
Abstract: Abstract Pools and riffles in gravel-bed rivers have a major effect on the variables of the flow equations. Obtaining measurements of these variables requires comprehensive research conducted in rivers. Detailed measurements were taken from one… read more here.

Abstract: Abstract A linearly depth-dependent diffusivity is commonly used to model the vertical distribution of dilute, near-bed, suspended sediment in marine fluid environments, i.e., the Rouse model; this simplified form predicts unfortunately infinite concentration at the… read more here.

DOI: 10.1121/1.4987957
Abstract: Sediment entrainment, transport, and deposition over bedforms can be highly dynamic with strong spatially temporal variability. To probe the multi-scaled processes of sediment transport, there has been continuing developments of instrumentation to obtain high resolution… read more here.

DOI: 10.1155/2017/2614943
Abstract: The near-bed sediment concentration and vertical sediment flux are important in sediment transport mechanics, but they are known much less than the horizontal sediment flux, especially for fine sediment in unsteady flows. A developed two-phase… read more here.
