2. Objectives and learning outcomes
2.1 Objectives
The aim of the course is to introduce the main questions and concepts of environmental system modelling: model identification, calibration, validation and sensitivity analysis. As part of this, different topics and various modelling approaches are presented, such as deterministic vs. empirical mathematical formulation of processes, distributed vs lumped parametrization, integrated hydrological modelling, soft computing methods for environmental problems, coupling of water and material flow models to describe complex pollution transport issues.
Air, surface and subsurface waters as well as artificial systems are among the described media. The introduced problems include the spread of air pollutants from point sources, hydrological processes of lowland watersheds, modelling of diffuse water pollution from nonpoint-sources, the design of infiltration beds in urban environment, the fate of groundwater pollution, etc.
