Environmental Fluid Mechanics is devoted to the publication of basic and applied studies broadly relating to natural fluid systems, particularly as agents for the transport and dispersion of environmental contamination. Understanding transport and dispersion processes in natural fluid flows, from the microscale to the planetary scale, serves as the basis for the development of models aimed at simulations, predictions, and ultimately sustainable environmental management. Within this scope, the subject areas are diverse and may originate from a variety of scientific and engineering disciplines: civil, mechanical and environmental engineering, meteorology, hydrology, hydraulics, limnology, and oceanography.The editors welcome reviews and original articles treating the atmosphere (on all spatial scales), surface water (wetlands, rivers, lakes, estuaries and oceans), and laboratory simulations of natural flows (thermals, plumes, jets, etc.). In addition, the journal is a medium for the publication of interdisciplinary studies on the interactions between natural fluid systems and their boundaries (ex. air-water surface exchanges, bottom sedimentation and resuspension, and exchanges between surface and subsurface waters) as well as interactions between fluids and their contents (ex. chemical and biological loads). Articles reporting observational, experimental, modeling and theoretical investigations are all appropriate.
