Topics in fluid mechanics, hydrology and hydraulics

Enrolment in academic year 3.

Passed problem-solving examination is a prerequisite for the theoretical part of the examination.

Topics in hydromechanics: Groundwater flow. Darcy’s law. Flow of real fluid: dynamic similarity, laminar and turbulent flow, boundary layer, drag force. Convective – diffusion equation.

Topics in Hydrology: Circulation of water and energy in the nature, water characteristics, surface runoff, runoff coefficient, snow and snowfall, hydrometry, measurement facilities, flow curve, the accuracy of hydrological measurements and observations. Basics of stochastic processes in hydrology. Unit hydrograph, its determination and use, the regionalization of hydrological phenomena, floods and hydrological forecasting, assessment of water balance.

Selected Topics of Hydraulic: Real fluid dynamics (flow regimes), open channel flow, steady non-uniform flow (hydraulic curve classifications, water levels calculation and

software), groundwater flow.

To obtain basic knowledge of hydrology, hydraulics and hydrodynamics of watercourses in nature in relation to the precipitation, snow cover, soil wetness, etc., and the topographical and geometrical features of the river basins, aquifers, etc.

Knowledge and understanding:

A set of subjects on water in nature. For understanding of the subject basic knowledge of physics is necessary.

Application:

A knowledge gained serves student of meteorology as a base for understanding of water and water processes.

Reflection:

Use of geo-physical methods and formalisms on examples of dynamic of the water body.

Transferable skills:

Understanding of cases about developments in the liquids by physical approach: consistency of the models with the observed development in nature.

Lectures, tutorials, seminars, visit of the labs.
