Environmental Fluid Mechanics

Module aims

  • To develop topics in fluid mechanics and hydraulics of broad interest to environmental engineers and hydrologists, and demonstrate the link between theoretical studies and their practical application in river and environmental engineering.

Learning outcomes

On successfully completing this course unit, students will be able to: 

  • Understand the fundamental properties of fluids.
  • Calculate pressures and forces exerted by fluids at rest.
  • Understand how fundamental equations of mass balance, momentum balance, energy balance, and friction losses are used to derive engineering equations that describe steady flow of water in open channels, associated water levels, pressures and forces.
  • Understand how channel expansions and contractions, and lateral inflow and outflow affect open channel flow behaviour.
  • Use that understanding to solve simple steady state open channel flow problems, including hydraulic jumps and flow profile sketching.
  • Understand how to apply the principles of fluids to solve simple problems of pressurized flow in pipes.
  • Understand how to apply the principles of fluids to solve simple problems of flow through porous media (EE only).
  • Distinguish between the alternative types of sediments in rivers and methods for estimating their transport (Hydrology only).
  • Recognise the links between the theory of fluid mechanics and the theories and practices taught in other related modules in this MSc (e.g. urban water, flood hydrology, hydrological processes, hydrogeology, water distribution systems, hydroinformatics). 

Module syllabus
