Experimental evidence for statistical scaling and intermittency in sediment transport rates
[1] Understanding bed load transport fluctuations in rivers is crucial for development of a transport theory and for choosing a sampling interval for “mean” transport rates. Field-scale studies lackExpand
On the influence of gravel bed dynamics on velocity power spectra
A series of flume experiments were conducted to study the effect of bed form dynamics on the flow over a gravel bed comprising a wide distribution of grain sizes. Instantaneous high-frequencyExpand
Microbial mat records in siliciclastic rocks: Examples from Four Indian Proterozoic basins and their modern equivalents in Gulf of Cambay
Abstract Microbial mat-related structures (MRS) in siliciclastics have been investigated from four Proterozic formations in India, namely the Marwar Supergroup, the Vindhyan Supergroup, theExpand
Multiscale statistical characterization of migrating bed forms in gravel and sand bed rivers
Received 14 October 2010; revised 24 October 2011; accepted 25 October 2011; published 20 December 2011. (1) Migrating bed forms strongly inuence hydraulics, transport, and habitat in riverExpand
On the homogenization of turbulent flow structures in the wake of a model wind turbine
The structure of flow turbulence, measured experimentally, in the wake of a model wind turbine is investigated here through higher order scale-dependent statistics of the velocity increments andExpand
Spectral description of migrating bed forms and sediment transport
This paper considers the problem of spatiotemporal bed topography evolution and sediment transport estimation in rivers with migrating bed forms of different types and sizes, in statisticalExpand
Coupled dynamics of the co‐evolution of gravel bed topography, flow turbulence and sediment transport in an experimental channel
A series of flume experiments were conducted in a large experimental channel at the St. Anthony Falls Laboratory to understand the coupled dynamics of flow and bed forms above the sediment-waterExpand
Subordinated Brownian motion model for sediment transport.
TLDR
This work proposes an extension of Brownian motion, called fractional Laplace motion, as a model for sediment transport which acknowledges the fact that the time over which the gravel particles are in motion is in itself a random variable and reproduces the multiscale statistics of sediment transport rates as quantified via a large-scale laboratory experiment.

Effect of Migrating Bed Topography on Flow Turbulence: Implications for Modelling Sediment Transport
Include a brief (<300 words) abstract, by itself, on p.2. Abstracts may not be published in the printed book but will be used in review and editing and may be used in web presentations of the bookExpand
