KurzbeschreibungComputational modelling of biogeochemical processes and transport of water and solutes in soils and aquifers.
LernzielRationale:
The content of the course builds on the students' basic knowledge in soil and aquatic chemistry as well as in soil physics (see below: Prerequisites).
This course addresses the modelling of impacts by pollutants on terrestrial and aquatic environments. It helps to acquire to model hydrological, geochemical and microbial processes in soils and aquifers in order to predict the mobility of contaminants in heterogeneous environmental systems. Computer models used will be provided by the internet platform PolyQL (http://www.polyql.ethz.ch).

Aims:
- Conveying the fact that there are different modelling approaches
- Learning how to parameterize physically-based models
- Developing skills for critical judgement of modelling results
- Applying theoretical models to real systems
- Gaining competence with web-aided learning
Inhalt- Applying computer models for biogeochemical and transport processes
- Chemical equilibria, speciation in aqueous systems
- Chemical kinetics, biogeochemical processes, redox processes
- Steady-state approach, serial-box models, sensitivity analysis
- Basic concepts in modelling water flow and solute transport
- Hydraulic processes in variably saturated soils
- Using models for pollutant transport in soils and aquifers
SkriptAvailable as hardcopy and on-line material.
