Environmental Transport Processes: Atmosphere-Water Exchange

Understanding how chemical substances move between water bodies and the air is vital for assessing water quality and predicting the fate of environmental pollutants. This text-based course guides you through the fundamental transport equations and physical laws governing gas transfer at the air-water interface. You will learn how to analyze and estimate the exchange rates of volatile organic compounds and essential dissolved gases. By studying key mass transfer models and laboratory estimation techniques, you will develop the analytical skills needed to solve real-world environmental engineering problems. What you'll learn: Understand the physical mechanisms driving gas exchange across the air-water boundary; Calculate mass transfer coefficients using standard environmental engineering formulas; Analyze the exchange rates of volatile compounds such as chloroform and dissolved oxygen; Learn the principles of gas chromatography and electrode measurements used to track concentration changes; Apply boundary layer theory to model environmental transport processes under different wind and flow conditions. This course starts with foundational concepts of diffusion, boundary layers, and mass transfer before moving into practical mathematical modeling and estimation scenarios. Designed specifically for beginners in environmental engineering, chemistry, or hydrology, this course requires no prior advanced modeling experience.
