Learning outcomes

Introduction to erosion, transport and sedimentation processes in rivers and reservoirs.
Basic knowledge about sediments in the channel.
Ability to create the study of sediment transport.
Knowledge of issues of the reservoirs sedimentation.

Prerequisites

Hydraulics, hydrology, soil mechanics, river regulations and weirs, open channel hydraulics.

Planned educational activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. Links to the final thesis and the possibility of further professional growth for example in doctoral studies.
Consultations are offered in response to a valid schedule of the teacher and students can also negotiate individually according to the needs and opportunities for students.

Forms and criteria of assessment

Attendance 90%, development of study. Successful completion of written test and oral exam.
