Learning Outcomes

The course material includes the basic concepts related to the study of Environmental Hydraulics problems. Emphasis is placed on the fundamental processes of transport and mixing of pollutants in water bodies.

With the successful completion of the course, the student will be able to:

• Use appropriate equations to determine the velocity field.
• Recognise the basic processes of transport and mixing of pollutants in water recipients.
• Determine the extent of pollution in water bodies.
• Study laminar flows and turbulent buoyant flows.
• Analyse the mixing and turbulent diffusion of veins and plumes.
• Design liquid waste disposal systems.
