Recent research explored an alternative energy-centred perspective on hydrological processes, extending beyond the classical analysis of the catchment's water balance. Particularly, streamflow and the structure of river networks have been analysed in

The moving layer at the surface of a granular bed sheared by a viscous flow has been investigated experimentally. The fluid and particle velocities have been measured using particle imaging velocimetry (PIV) and particle tracking, respectively, with

In this paper, we present laboratory measurements at high Reynolds numbers of the turbulence generated by breaking internal-gravity waves of flow over Gaussian-shaped obstacles. The results confirm that the flow evolution leading to wave-breaking for

Experiments are reported on the dynamics of a bed of particles sheared by a viscous Couette flow in an annular channel, with emphasis on the distributions of particle velocities, durations and lengths of the small saltation flights, and surface densi

Experimental results are presented on the lee-wave breaking process which occurs at low Froude numbers when uniform and strongly stratified flow approaches two-dimensional and quasi two-dimensional Gaussian-shaped obstacles. It was found that the lee

An experimental investigation of the three-dimensional density structure of far-wake vortices generated by moving a sphere in a linear saline stratification has been carried out via conductivity measurements. These measurements were performed in the

This article discusses the structure of the far-wake of a towed sphere in a saline stratification. We compare very low Froude number experiments to existing results at higher Froude numbers and investigate the vertical structure of the far-wake in te

When internal waves generated by flow over mountains break under sufficiently stably stratified atmospheric conditions, a localized turbulent zone is created. This is one important example of the mechanisms which engender so-called ‘clear air turbu

Under stably stratified atmospheric conditions, standing internal waves are generated when the flow passes over an obstacle such as a mountain. When the stratification is sufficiently strong, these waves can break, leading to a localised turbulent zo
