Courses
ESE 1. Introduction to Environmental Science & Engineering. 9 units (3-0-6); third term. Prerequisites:Ph 1 ab, Ch 1 ab, and Ma 1 ab. An introduction to the array of major scientific and engineering issues related to environmental quality on a local, regional, and global scale. Fundamental aspects of major environmental problems will be addressed with an overall focus on the dynamic interplay among the atmosphere, biosphere, geosphere, and hydrosphere. Underlying scientific principles based on biology, chemistry, and physics will be presented. Engineering solutions to major environmental problems will be explored. Satisfies the menu requirement of the Caltech core curriculum. Not offered on a pass/fail basis. Instructor: Hering, Hoffmann.
ESE 142. Aquatic Chemistry. 9 units (3-0-6); second term. Prerequisites:Ch 1, Ch 14, or instructor’s permission. Principles of inorganic and physical chemistry applied to natural and engineered aquatic systems. Biogeochemical processes controlling the major ion composition of aquatic systems and the behavior of the trace inorganic constituents of such systems are examined. Fundamental aspects of thermodynamics and quantitative description of the composition of natural waters are stressed. Instructor: Hering.
ESE 144. Applications of Aquatic Chemistry. 9 units (3-0-6); first term. Prerequisites:ESE 142. Case studies are used to illustrate the effects of biogeochemical processes on the composition of ground and surface waters. Systems to be examined include natural waters subject to varying levels of perturbations as a result of human activities and engineered systems, such as constructed wetlands or water treatment systems. Quantitative equilibrium and kinetic modeling are emphasized. Instructor: Hering.
