Synopsis:

The course focuses on numerical modelling of free surface water flow and its application in practical hydraulic problems of river hydraulics. In terms of dimensionality, it focuses mainly on the problems of one-dimensional and two-dimensional modelling. The theoretical part of the course is devoted to the general possibilities of investigating flow characteristics, mathematical description of flow, classification of numerical models of water flow with a focus on the mathematical formulation of the initial system of governing equations, approaches to turbulence modelling, spatial schematisation, discretization and numerical solution of the problem using the most used methods of solving governing equations (finite difference method, finite element method, finite volume method). On a practical level, the course covers the conditions for practical application of models, requirements for input data and their accuracy, including the use of modern remote sensing data, specification of boundary conditions, calibration of models, and methods of evaluating results and presenting outputs.

Requirements:

The interrelationship between the student's study focus and the anticipated content of his/her dissertation and the content of the course. Knowledge from previous studies (mathematics, hydraulics).
