The study of the Earth and the environment requires an understanding of the physical processes within and at the surface of the Earth. This book will allow the student to develop a broad working knowledge of mechanics and its application to the earth and environmental sciences. The mathematics are introduced at a level that assumes only an understanding of first-year calculus. The concepts are then developed to allow an understanding of the basic physics for a wide range of natural processes. These are illustrated by examples from many real situations, such as the application of the theory of flow through porous media to the study of groundwater, the viscosity of fluids to the flow of lava, and the theory of stress to the study of faults. The breadth of topics will allow students and professionals to gain an insight into the workings of many aspects of the Earth's systems.6.10 Dispersion by flow One of the main practical reasons for the study of groundwater is to ensure that water pumped from ... We consider first the general question of how tracers are carried by a flow, and then some aspects peculiar to flow through porous media. ... Two small parcels of fluid, originating in two adjacent pores, are constrained by the pore geometry to split, spread out and mix flow pathsanbsp;...
