Rough surfaces are ubiquitous in nature. Near-surface processes both encounter and create
surface roughness. Recent advances in surveying have improved the resolution, extent and …

ABSTRACT A wind tunnel experiment has been performed to quantify the Reynolds number
dependence of turbulence statistics in the wake of a model wind turbine. A wind turbine was …

We develop a coupled hydro-morphodynamic numerical model for carrying out large-eddy
simulation of stratified, turbulent flow over a mobile sand bed. The method is based on the …

The deployment of in-stream flow-energy converters in rivers is an opportunity to expand the
renewable energy portfolio and limit carbon emissions. Device performance and lifetime …

Riverbed elevations play a crucial role in sediment transport and flow resistance, making it
essential to understand and quantify their effects. This knowledge is vital for various fields …

Knowledge of hydraulic resistance of single-valued self-affine fractal surfaces remains very
limited. To advance this area, a set of experiments have been conducted in two separate …

In gravel bed rivers, bed load transport exhibits considerable variability in time and space.
Recently, stochastic bed load transport theories have been developed to address the …

This paper reports an experimental investigation of open channel turbulent flow between
two inline surface mounted hemispherical obstacles in tandem arrangement. A series of …

Understanding how landscapes respond to climate dynamics in terms of macroscale
(average topographic features) and microscale (landform reorganization) is of interest both …

Migrating bed forms strongly influence hydraulics, transport, and habitat in river
environments. Their dynamics are exceedingly complex, making it difficult to predict their …
