Special Issue Information

Dear Colleagues,

Turbulence is omnipresent and even common whenever dealing with fluid flows, whether considering flowing through small scales domains, such as pipes, or through large scales ones, such as in the atmosphere and the ocean-surface boundary layers. Turbulence has a significant impact on the coastal dynamics processes, where its microstructure and transport properties crucially influence the water column properties from the physical and the biogeochemistry points of view. In addition, turbulence is important when considering fluxes and processes at the ocean-atmosphere interface, while marine and atmospheric turbulence play an important role in meteorology and climatology. On the other hand, solving turbulence remains today an important issue and a theoretical challenge. In most cases, a common approach consists, in general, of parameterizing the turbulence through semi-empirical formulations.

The main goal of this Special Issue is aimed at building synergies between fundamental and applied approaches of turbulence, with special emphasis on the coastal environment in order to bring together different experts and models, including marine, atmospheric and climatological sciences. We welcome papers dealing with theoretical, modelling, applied and observational approaches of turbulence that allow a better understanding of its advancement and applications.

This Special Issue covers the following topics:

  • Turbulence in fluid dynamics: State-of-the-art;
  • Turbulence in the atmosphere and coastal water dynamics;
  • Turbulence and transport processes at the atmosphere and ocean interface: interactions;
  • Turbulence and physical and biogeochemical interactions in coastal areas;
  • Turbulence and sediments transport in coastal areas;
  • Turbulence and waves generation in coastal areas;
  • Turbulence and tidal processes in shallow coastal areas;
  • Turbulence: ocean and atmosphere models.

Turbulence modelling is an important issue when dealing with hydrodynamic and transport models for better simulation of the transport of dissolved or suspended substances in a body-water. It controls processes involving physical balances (salt and water temperature) and, therefore, the ecosystem equilibrium. The study arises from the need to model the turbulence more efficiently when dealing with extreme situations on the Ria de Aveiro (Portugal), a coastal lagoon shallow water system dominated by tidal transport. Because the turbulence model is coupled to the hydrodynamic and transport models, a correct estimation of the eddy viscosity is important in simulating the salt and the heat transports. The aim is to assess the performance of four turbulence schemes/models (k, k-ε, Smagorinsky’s, and k-ε/Smagorinsky’s (k-ε/Sma), where k is turbulent kinetic energy and ε the dissipation rate of the turbulent kinetic energy) associated to a coupled hydrodynamic and transport models to simulate the eddy viscosity, the salinity, and the temperature. Overall, the results point out that among the different models/schemes used, the is the one which provides a more realistic value of the eddy viscosity within the range (1–6) m2 s−1, but most probably (1–3) m2 s−1. The application of the sensitivity analysis to some non-universal k-ε/Sma parameters evidenced significant sensitivity for the eddy viscosity and the salinity and moderate sensitivity for the water temperature. A 100% adjustment of the parameter values relative to the reference, translated into variations within the range of (1, 4) m2 s−1, (0, 13) PSU, and (1, 2.20) °C, for the eddy viscosity, salinity, and water temperature, respectively.
