Synopsis:

Definition of the environmental system, modelling procedure, multicompartment analysis, verification and validation. Methods of determination of submodels parameters. Chosen methods of solution of ordinary and partial differential equation. Simulations with codes modelling simple and/or complex environmental systems. Practical demonstration and exercise: contaminant sorption on natural materials, modelling population dynamics, speciation and migration codes.

Requirements:

Matematics and physical chemistry (or physics) on the bachelor-degree level.

Syllabus of lectures:

1.Physical and mathematical models, models as a management tool, models as a scientific tool

2.System, types of behaviour: dynamic, chaotic, catastrophic.

3.Basic types of ecological models: „black box“ and conceptual models, multicomartment analysis.

4.Overview of basic methods of solution of ordinary and partial differential equations.

5.Computer model, analogy and digital modelling.

6.Verification and validation of computer model, analysis of uncertainty influences.

7.Equilibrium and kinetic models of partial models, fitting of parameters of partial processes.

8.Biological and environmental models of population dynamics.

Syllabus of tutorials:

1.Solution of ordinary and partial differential equations

2.Simulation experiments: factor and optimalization modelling.

3.Contaminants sorption on a natural material.

4.Speciation of radionuclides in complex systems.

5.Modelling of diffusion in the GoldSim environment.

6.Migration of radionuclides in the near-field of repositories.

Study Objective:

The course is aimed to the formulation and keeping under review of models of complex systems. The knowledge of that enables students to obtain competence to appreciate the influence of models of partial processes on the behaviour of complex environmental systems.
