Prerequisites
Working knowledge in topics such as Hydrology, Applied Hydraulics, River Dynamics
Learning objectives
- Familiarize participants with structure of equation systems, numerical solution techniques and their representation in modelling systems and practical use of these.
- Provide participants practical experience with standard models and develop an understanding of steady flow modelling in rivers.
- Introduce participants with the use and design of hydraulic model studies as a tool for improving hydraulic engineering solutions.
Syllabus
Computational Hydraulics (I. Popescu)
The course aims to introduce numerical aspects
of modelling, so that students become aware of the limitations and characteristics
of hydrodynamic numerical models. The course starts with a short
overview of the differential equations used in hydraulics, principles of
discretisation of shallow water equations in 1D. Further the concept of
Courant number, stability and accuracy, will be introduced for both implicit
and explicit schemes. Emphasis will be on river applications and
short wave propagation.
Physical Models (M. Sterling)
Physical laws and modeling. Application area
of physical models. Application of dimensional analysis in theory of similarity.
Derivation and use of scale laws, and conditions. Scale effects,
accuracy of measurements and costs as determining factors for scale selection.
Design, calibration and verification of hydraulic scale models. Reproduction
of various hydraulic phenomena like 2D and 3D flows in rivers, over and
through the hydraulic structures, sediment transport, morphology, air entrainment
and local scour.
Modelling Practical (I. Popsecu and L.
Beevers)
Through a case-study approach practical experience
with computational numerical models will be gained by students. This
will take the form of either lake or river modelling. The objective
of this component will be the application of the theory gained in the theoretical
components of the course.
