Turbidity currents are important ocean dynamic processes that influence sediment transport,
ocean engineering, and marine environments. As a turbidity current evolves, its macroscopic …

We perform the linear and weakly nonlinear stability analyses of longitudinal sediment
waves triggered by the interaction of turbidity currents with an erodible bed. The …

Understanding gravity currents developing on complex topography, which involve
turbulence and mixing processes on a wide range of spatial and temporal scales, is of …

We report experimental results on the injection of a heavy fluid into a light one in a closed-
end pipe, inclined at intermediate angles. The injection of the heavy fluid is made using an …

A large-scale experimental study has been conducted at the Coriolis Rotating Platform to
investigate the dynamics of uni-and bi-directional exchange flows along a channel with a …

We propose a mathematical model describing the mixing and propagation of nonlinear long
waves in a shear three-layer flow of a stratified fluid under a lid. The shallow water equations …

The present work investigates the use of physics-informed neural networks (PINNs) for the
three-dimensional (3D) reconstruction of unsteady gravity currents from limited data. In the …

Settling of solid particles in the fluid is one of the most basic forms of sediment transport.
However, due to the complex particle–particle and particle–fluid interactions, the mechanism …

Gravity currents produced by a lock-exchange flow are studied using high-resolution
molecular tagging techniques. Instead of employing salt to produce density stratification, an …

The Schmidt number, defined as the ratio of scalar to momentum diffusivity, varies by
multiple orders of magnitude in real-world flows, with large differences in scalar diffusivity …
