Preface to the Special issue of Environmental Fluid Mechanics in Honour of Peter A. Davies

This special issue of Environmental Fluid Mechanics comprises a set of papers submitted in honour of Peter Davies who retired in 2020 as Professor of Fluid Dynamics at the University of Dundee (UoD), UK, after decades of service to the environmental fluid mechanics community and a founding associate editor of this journal. He spent practically all of his academic faculty career in the Department of Civil Engineering at UoD, where he established an internationally-leading research group in Environmental Fluid Mechanics and Geophysical Fluid Dynamics, with a focus on density-stratified flows, buoyancy-driven flows, rotating flows, ocean wastewater systems and remote sensing of coastal processes. During his 40 years at UoD, he served twice as Head of Department and contributed extensively to the research strategy and performance of the University.
