Learning outcomes

The aim of the course is to introduce the student to the erosion, transport and deposition processes in rivers and reservoirs.
The student will acquire basic knowledges about the physical properties of sediments and deposits, the transport of sediments, the calculation of their dischrge, the possibilities of their modelling and measurement, and the prediction of the evolution of river channels and the deposition of reservoirs.
The basic skill of the graduate is the ability to process a sediment study of the river reach.


Hydraulics, hydrology, soil mechanics, dams, reservoirs, river training and weirs.

Planned educational activities and teaching methods

Teaching methods, namely lectures and exercises, are described in Article 7 of the BUT Rules for Studies and Examinations. Perhaps it is a follow-up to the assignment of the final thesis and another professional growth in doctoral studies.
The consultation hours are offered individually according to needs and possibilities of the student and the teacher.

Forms and criteria of assessment

Credit: Attendance at least 90%, elaboration and presentation of a sediment study of a selected river reach.
Examination: At least 50% of the correct answers to the questions in the written test and the successful completion of the oral exam.
