In a framework of changing climate, it is important to find alternative solutions for coastal protection. Indeed, the pressure of anthropogenic origin, combined with natural forcings, has contributed both to a worsening of the environmental quality o

We present a technique for measuring the two-dimensional surface water wave elevation both in space and time based on the low-cost Microsoft Kinect sensor. We discuss the capabilities of the system and a method for its calibration. We illustrate the

Turbulence plays a major role in shaping marine community structure as it affects organism dispersal and guides fundamental ecological interactions. Below oceanographic mesoscale dynamics, turbulence also impinges on subtle physical–biological coup

Irreversibility inversions in two-dimensional turbulence

Autor: Andrew D. Bragg, Guido Boffetta, Filippo De Lillo

An analysis shows that in 2D turbulence the nature of the irreversibility of two-particle dispersion inverts when the particle inertia exceeds a certain threshold. The results also imply that in turbulent flows with an inverse energy flux, inertial p

We investigate the spatial distribution of inertial particles suspended in the bulk of a turbulent inhomogeneous flow. By means of direct numerical simulations of particle trajectories transported by the turbulent Kolmogorov flow, we study large and
