Learning objectives:
The aim of the course is to provide students with the basis for the analysis of river systems and of the hydraulic
structures regulating them. The course provides a deeper insight in the phenomena of rapidly varied flow,
unsteady flow and sediment transport, and provides them with a methodology for problem analysis and design,
using physical and/or numerical models.
Course description:
1. Methodology of hydraulic studies; data needs and sources;
2. Principles of similitude:
fixed bed models; mobile bed models; thermal models;
3. Rapidly varied flow in open channels:
hydraulics of spillways; hydraulic jump and energy dissipation; flow in channels; nonprismatic channels;
4. Unsteady flow in open channels:
derivation of the equations of continuity and of motion for unsteady free surface flow (Saint Venant
equations); solution by the method of characteristics, physical interpretation of the characteristic directions;
finite difference solutions by explicit and implicit schemes; parabolic and diffusion approximations;
Muskingum-Cunge approximation; kinematic wave approximation. Computer based exercises: Two
didactic computer programs and two professional softwares are used to illustrate the principles of unsteady
flow analysis, the application of flood routing in large streams and the modeling of flow propagation in
small upland watersheds.
5. Sediment transport:
physical basis of flow in eroding channels; mechanical and hydraulic characteristics of riverbeds and
sediment transport; mechanism of sediment transport; and
6. Channel processes:
hydrodynamic and hydromorphological approach to the channel processes theory; basic riverbed processes
produced by the construction of hydraulic structures, channel stabilization and dredging.
The practical work consists of:
- Design of physical models;
- Spillway design;
- Flood routing models: FLDWAV (Hydrologic Research Laboratory, National Weather Service, USA),
- Simulation of flows in upland watersheds: KINEROS ( Agricultural Research Service, USA)
- Sediment transport.
