Environmental Fluid Mechanics provides comprehensive coverage of a combination of basic fluid principles and their application in a number of different situations, exploring fluid motions on the earth's surface, underground, and in oceans. The authors detail the use of physical and numerical models and modern computational approaches for the analysis of environmental processes. They cover novel scaling methods for a variety of environmental issues, equations of motion for boundary layers, the advection diffusion equation, sediment and associated contaminant transport in lakes and streams, mixed layer modeling in lakes, remediation, transport processes at the air/water interface, and more.
