COURSE AIM
To give the foundations of open channel flow and recipient hydraulics.
CONTENTS
Open channel flow:
Uniform and gradually varied flow: the Manning equation, hydraulic jump, sub- and supercritical flow.
Hydraulic structures: Sharp-crested weirs, Contracted weirs, Vee weirs, Control gates, Spillways (WES).
Surge waves: positive and negative waves, propagation speed.
Sediment transportation: design of stable alluvial channels, bottom load, suspended load, bottom configuration, critical shear stress, etc.
Recipient hydraulics:
Compound channels: effect of internal turbulent shear stresses, the TDMA-algorithm, open channel flow generalized in two dimensions
The atmospheric boundary layer
The Baltic sea
Dynamics of lakes: Langmuir cells, seiches, energy balance, the Coriolis force, stratification, influence of wind, etc.
Diffusion: the diffusion equation, Fick´s law, advection, one- and two-dimensional mixing, river mixing etc.
Jets and plumes
Numerical modelling: the finite volume approach, modelling of water quality.
TEACHING
EXAMINATION
The course is examined by several tests made at home. Participation in laborations and project work is compulsory.
