Course content

Sediment transport theory, the theory of physical hydraulic modelling and the use of water resources in sediment loaded rivers. Extended discussion on reservoir sedimentation, planning and design of headworks for run-of-river hydropower plants, sediment handling techniques, sediment sampling and analysis of sediment data.
