Course handbook


This course introduces students to the notions of mixing, diffusion and dispersion modelling. It extends the theories presented in CIVL2310 Fluid Mechanics to include methods of modelling surface water flows. It also presents modelling of surface water transport processes using convection-diffusion equations and particle tracking methods and describes aquatic chemical and biological processes and examines their kinetics using a range of models. The course introduces methods of estimation of parameters in water quality or ecosystem models.

Learning outcomes

On successful completion of the course students will be able to:

1. Formulate hydrodynamic, mixing and dispersion problems in aquatic environments

2. Formulate chemical and biological problems in aquatic environments

3. Apply and optimise state-of-the-art entry level hydrobiological models in defined applications

4. Estimate parameters in selected predictive models

5. Summarise and interpret the research literature and apply it to practical problems.


1. Introduction to models. 2. Types of models. 3. Transport concepts and definitions. 4. Modelling the diffusion equation. 5. Physical processes in water bodies. 6. Dispersion processes. 7.
