The chapter discusses the modeling of pollutant transport using box models, focusing on water and air quality. It emphasizes defining the system domain, boundary conditions, and initial conditions necessary for accurate modeling. Complexities such as system dimensionality and mechanisms of mixing, including convection and boundary layer effects, are also highlighted.

Term: Box Model
Definition: A simplified representation used to understand the transport and reaction of pollutants in a defined system boundary.
Term: Mixing Height
Definition: The vertical extent in which pollutants are assumed to mix uniformly in the atmosphere.
Term: Convection
Definition: The movement of air due to density differences caused by temperature variations, impacting pollutant dispersion.
Term: Boundary Layer
Definition: The region where friction with the Earth's surface affects air movement, leading to variations in velocity.
