10. Transport of Pollutants - Box Models in Water
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.

What we have learnt
- Box models are essential for understanding pollutant transport in water and air systems.
- Defining boundaries and conditions is critical for accurately modeling environmental systems.
- Mixing height and convection mechanisms play significant roles in pollutant dispersion.
Key Concepts
- -- Box Model
- A simplified representation used to understand the transport and reaction of pollutants in a defined system boundary.
- -- Mixing Height
- The vertical extent in which pollutants are assumed to mix uniformly in the atmosphere.
- -- Convection
- The movement of air due to density differences caused by temperature variations, impacting pollutant dispersion.
- -- Boundary Layer
- The region where friction with the Earth's surface affects air movement, leading to variations in velocity.
