CR053 course is part of 1 study plan

Ing. full-t. program nC > V compulsory-elective Winter Semester 2nd year 5 credits

The course provides students with information on the safety assessment of the water works during floods. N-year flows in the profile of the dam determining, design discharge, transfer the flood waves and its transforming through the reservoir. The use of emergency spillways and bottom outlets of dams for controlled transfer of flood waves. Converting of the control flood waves. The design of the emergency spillways, spaces of stilling basins and spillway channel for safe operation during floods. Designing of the multipurpose flow control structure of small dams and polder dams. Function and Designing of the surge tank of the hydropower plant. Water hammer exclusion of the direct impact in long pipelines and pumping stations circuits.

Learning outcomes

The course builds on the knowledge of the subjects of hydraulics, hydrology, dams, weirs, hydro power utilization. Introduction to the designing of appurtenant structures for dams for the safe transfer of flood flows, which include spillways, chutes bottom outlets, sewage tunnels and objects for the control of kinetic energy flow. Students will get acquainted also with hydraulic solution of the surge tanks and eliminating water hammer effect.


Hydraulic, dams, hydrology, river training and weirs, hydro power utilization. Basic knowledge of statistics.


Metal construction of hydraulic structures, mathematical modelling in water management.

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. In the course will be presented the photos and videos of converting flood on the safety of the tests on scale models and objects of their own works. Students get acquainted with the latest tests in the laboratory model parts or complete the security object of the water works.

Forms and criteria of assessment

Successful conclusion of the course requires the completion of exercises with the granting of credit for the course. The credit required protocols focused on the various proposals of the object.


Methodology and solution of hydrodynamic phenomenons including their modelling

Specification of controlled instruction, the form of instruction, and the form of compensation of the absences
