1. Introduction to open channel flow
2. Basic theory of open channels flow
3. I. Mathematical formulation of 1D flow problem
4. II. Mathematical formulation of 1D flow problem
5. Saint-Venant equations
6. Mathematical formulation of the problem of transportation and dispersion
7. Numerical solution
8. The movement of sediment load
9. The issue of determining the open channel roughness
10. Practical problems the flow calculation
11. Structures on streams (weirs, bridges, culverts)
12. Hydraulic solutions crossing bridges and culverts with watercourses
13. The issue of ice phenomena on rivers
The aim of the course is to acquaint students with principles of hydraulics of open channels. In this course solves water flow in open channels, ie consistently uniform and non-uniform flow, sediment movement. The content of the course is also hydraulic solution of buildings on watercourses such as weirs, bridges and culverts. For solving hydraulic task is used 1D Software HEC-RAS. The course includes specific examples of completed projects.
The students will obtain knowledge about nonuniform steady flow and unsteady flow, about transport and dispersion of conservative component in rivers and about transport of sediment.
