Environmental Turbulence: From Fundamental Physics to Critical Applications explains how to understand environmental and geophysical turbulence, both at a theoretical level and in engineering applications. Sections cover the effects of these new features on the fundamental flow dynamics in relatively simple domains. That is, how the turbulence statistics and structure are modified by the stabilizing or destabilizing effects of buoyancy and rotation is surveyed. Scalar transport is also described in detail. Flow in more complex domains is then described, focusing on vegetated and urban canopies, wind farms, air-sea interfaces, the upper ocean and clouds.

Turbulence in environmental media is strongly modulated by buoyancy forces at all scales and by rotation at the largest scales, in contrast to canonical turbulent flows. It is rarely steady, which can give rise to non-equilibrium effects, and the domains such as wind farms or cities are often quite complex, leading to more intricate dynamics than in classic wall-bounded or free shear flows.

Professor Elie Bou-Zeid is the Director of the Program in Environmental Engineering and Water Resources in the Department of Civil and Environmental Engineering at Princeton University. He is also director of the Metropolis Project (https: //metro.princeton.edu/) of the School of Engineering and Applied Science. He is an associated faculty member in the Department of Mechanical and Aerospace Engineering and in the Program in Atmospheric and Oceanic Sciences. His work focuses on the integration of theoretical, numerical and experimental approaches to flow and turbulence in environmental systems, with a particular focus on applications related to the built environment, complex and heterogeneous terrain, and wind energy. He is the recipient of the "Fondation Latsis Internationale" University Award (2009) and the E. Lawrence Keyes Jr. / Emerson Electric Co. Faculty Advancement Award from Princeton University (2011).

Professor Sutanu Sarkar is a Distinguished Professor, holder of the Blasker Chair of Environmental Engineering, and Affiliate Professor of the Scripps Institute of Oceanography. His honors include a NASA group achievement award (1994), Friedrich Wilhelm Bessel Research Prize (2001) from the Humboldt Foundation, Fellow of the American Physical Society (2006), Associate Fellow of the American Institute of Aeronautics and Astronautics (2010) and Fellow of the American Society of Mechanical Engineers (2010). His work uses computational fluid dynamics to study multiscale, unsteady flow problems. His recent research concerns flows in the natural environment where he brings techniques of modern computational science to predict turbulence, transport of pollutants and tracers, and submersible wake dynamics and wind turbine interactions with the atmospheric boundary layer.
