Entry knowledge

Basic knowledge in the field of Water Management and Water Structures, basic knowledge of mathematics, physics, hydraulics and hydrology.

Rules for evaluation and completion of the course

Extent and forms are specified by guarantor’s regulation updated for every academic year.

Aims

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.


Students complete goal of this course which include getting up principles of flow in the open channels. Also students get experience in flow in the open channels through term projects.
