Physical Principles of Sedimentology is a textbook devoted to the physics of sedimentological processes. The applicability of fundamental principles, such as Newton''s Three Laws of Motion, Law of Conservation of Energy, First and Second Laws of Thermodynamics, and of other physical relations in hydraulics and groundwater hydrology is illustrated by discussions of natural processes which form sediments or sedimentary rocks. The author''s educational background as a major in physics and geology, and his 40-year experience in teaching and research help him bring together physics and geology in this enjoyable and highly readable form.
