The chapter discusses the air-water exchange processes, focusing on estimating the mixing length and performing Gaussian dispersion exercises. It covers the roles of mass flow, evaporation rates, and mass transfer coefficients in determining pollutant concentrations in interconnected air and water systems. The impact of assumptions, such as well-mixed conditions and initial chemical concentrations, on modeling and calculations is emphasized.
