Learning outcomes of the course unit

The result is the ability of graduates to classify problems in water management in terms of modelling, to demonstrate approaches at deriving governing equations in water related disciplines (mass and energy balance, momentum conservation, equations of state) and to specify boundary and initial conditions. The course deals with strain-stress problems, seepage hydraulics, dam break modelling and pollution transport in open channels.

Prerequisites

Mathematics, Hydraulics, Statics, Strain and stress analysis

Co-requisites

Numerical methods, statistics

Aims

The aim is to classify hydrodynamical problems in terms of mathematical modelling, to demonstrate approaches at deriving governing equations in fluid mechanics (mass and energy balance, momentum conservation, equations of state) and to specify boundary and initial conditions. The course deals with laminar and turbulent modelling, open channel and floodplain hydraulics and groundwater flow.
