Geochemical modelling of groundwater 1300-TMGWP

The aim of the course is to familiarise students with:
- types of geochemical systems;
- phases and forms of substances in groundwater;
- types of reactions in hydrogeochemical systems;
- terminology used in geochemical modelling, incl. fundamentals of the chemical thermodynamics (free enthalpy, enthalpy, thermodynamic potential, activity)
- historical development and classification of geochemical models;
- importance of the range and the quality of input data (analytical field and laboratory data, thermodynamic data and their internal consistency);
- role of hydrological, mineralogical, thermodynamical and kinetics factors in geochemical modelling;
- applying isotope data in geochemical modelling, reactive transport modelling (assumptions of local equilibrium);
- application and interpretation of the results of speciation-solubility modelling (using speciation calculations in environmental issues. Constructing, application and interpretation of solubility curves, solubility diagrams, diagrams of stability fields. Saturation state);
- rules of construction of conceptual models. Calculation and verification of conceptual models;
- interpretation of case studies, mainly inverse mass balance and forward modelling;
- requirements and limitations of geochemical modelling;
- examples of the use of modelling (self-performance of calculations and discussion).
