Learning outcomes of the course unit

The graduate obtains knowledge about the foundations of open-channel hydraulics and learns to use in solving problems of flow in river networks program HEC-RAS. The graduate is able to:
explain basic concepts of open-channel hydraulics
describe the fundamentals of fluid flow in channels
anylyze a given problem
apply knowledge of program HEC-RAS to the calculation of flow in the channel
present the results of the individual assignment

Prerequisites

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

Co-requisites

Fundamentals of mathematical modeling.

Planned learning 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.
The course is complemented by excursions and expert presentation.

Assesment methods and criteria linked to learning outcomes

Successful conclusion of the course requires the completion of exercises with the granting of credit from the course, compliance with computing and conceptual part of the written test and the actual examination.

Aims

The aim of the course is to acquaint students with principles of hydraulics of open channels. 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.

Specification of controlled education, way of implementation and compensation for absences

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

Recommended optional programme components

It is possible collaboration on research projects in the field of floodplain.
