The 2004 Sumatra earthquake and the associated tsunamis are one of the most devastating natural disasters in the last century. Several fault plane models have been suggested to represent the rupture mechanism of the earthquake. During this tsuna[...]

Simultaneous measurements of three-dimensional velocity components and free-surface elevations were carried out in the lagoon of Fogliano, to investigate the statistical characteristics of turbulence produced in the flow by the action of wind ov[...]

A numerical study is presented of horizontal wind-induced mixing in shallow water basins. The shallow water equations are solved on a dynamically adaptive quadtree grid using a Godunov-type finite volume scheme to predict the wind-induced flow f[...]

The effect of flow geometry on wind-induced particle advection in non-circular shallow basins is investigated by means of a particle tracking advection model combined with a finite volume solver of the shallowwater equations. Acompanion paper de[...]

Management of coastal waters and lagoons by mathematical circulation models requires determination of the hydraulic resistance of submerged vegetation. A plant typical of sandy coastal bottoms in the Mediterranean Sea is Posidonia oceanica, whic[...]

A Reynolds stress model for the numerical simulation of partly-vegetated flows is presented. The model uses Speziale, Sarkar, and Gatski’s model for the pressure–strain correlation, Mellor and Herring’s model and Rotta’s model for the diffusion [...]

Experiments using two, three or five interacting identical round vertical turbulent buoyant jets were performed, using tap water as the jet liquid and salt water as the ambient liquid. Measurements were made of the centreline axial velocity and [...]

Based on the superposition of pertinent fluxes of single jets or plumes, a model to predict the mean axial velocities and mean concentrations of the combined field due to merging is developed. The model equations are produced by the integral equ[...]

The variation of the mechanical energy for the mean, oscillating and turbulent flows are considered. Their mean point out the contribution of the unsteadiness to the viscous losses and the turbulent production. A two-dimensional turbulent pulsat[...]

This paper investigates numerically characteristics of the fluid flow and solute transport in variable-aperture fractures under effective normal stress conditions. In order to represent a nonlinear relationship between the supported effective no[...]

By increasing the velocity of flow in coarse grain materials, local turbulences are often imposed to the flow. As a result, the flow regime through rockfill structures deviates significantly from linear Darcy law; and nonlinear or non-Darcy flow[...]

Unlike Newtonian open channel flow, not much work has been done to study the flow behaviour of non-Newtonian fluids in open channels. A scarcity of water worldwide has forced design engineers to increase the solid concentrations when designing f[...]
