Learning outcomes of the course unit

The graduate obtains knowledge about the foundations of hydrostatics, hydrodynamics and hydrology. The student is able to:
- Explain basic concepts of hydrostatic
- Describe the fundamentals of fluid flow
- Explain the phenomena arising from the flow of water in pressure systems and open channels
- Describe the water cycle in nature
- Explain the parameters describing the qualitative and quantitative parameters of water in nature

Prerequisites

Basic knowledge of mathematics, physics, mechanics and statics.

Co-requisites

Concrete and metal structures, soil mechanics.

Planned learning activities and teaching methods

Course lectures are supplemented by presentations of mathematical and physical research of flow (eg modeling of the flooded area, etc.). During the semester, students watch demonstrations of hydraulic models in the laboratory of the institute.

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.

Course curriculum

1.-2. Hydraulics, fluid properties, hydrostatic, pressure forces on plane and curved surfaces, floatation.
3. Hydrodynamics, continuity and momentum equation, Bernoulli equation, application of impulse theorem.
4.-5. Water flow in pressure pipeline systems, laminar and turbulent flow. Calculation of hydraulic long and short pipes and combined pipes. Inverted siphon, sucker, pump design.
6.-7. Steady uniform flow with free surface in open channels. Energetic head of profile. Critical flow. Supercritical and subcritical flow.
8. Overflow of water on overfalls. Orifice discharge and overfalls with reservoirs.
9. Hydraulic jump with bottom regime. Connection of water surface of two pools, design of rectangle stilling basin.
10. Hydraulic computation of typical communication objects, bridges and culverts.
11. Basics of groundwater flow (Darcy’s formula, filtration velocity, filtration coefficient, Dupuit theorem, groundwater flow in surrounding of a well)
12. Hydrology: occurrence of water and water cycle, hydrological balance, definition and characteristics of watershed, precipitation, evaporation, measurement of hydrological variables.
13. Surface runoff from watershed and its determination. Flow regimes in open channels. Maximum and minimum discharges, M-day and N-year discharges, winter regime, influence on runoff regime, influence of reservoirs on regulation of outflow from watershed, etc.

Aims

By attending the course students will get basic information on behaviour of fluids, phenomenons generated in water flow in pressure system and open channels. The students will also learn the information on water cycle in nature and measuring of related qualitative and quantitative parameters.

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 hydraulics.
