AbstractThe course provides theoretical and practical foundations for understanding and characterizing physical and transport properties of soils/ near-surface earth materials, and quantifying hydrological processes and fluxes of mass and energy at multiple scales. Emphasis is given to land-atmosphere interactions, the role of plants on hydrological cycles, and biophysical processes in soils.

- quantify driving forces and resulting fluxes of water, solute, and heat in soils.
- apply modern measurement methods and analytical tools for hydrological data collection
- conduct and interpret a limited number of experimental studies
- explain links between physical processes in the vadose-zone and major societal and environmental challenges

701-1315-00LBiogeochemistry of Trace ElementsO3 credits2GA. Voegelin, M. Etique, L. Winkel
AbstractThe course addresses the biogeochemical classification and behavior of trace elements, including key processes driving the cycling of important trace elements in aquatic and terrestrial environments and the coupling of abiotic and biotic transformation processes of trace elements. Examples of the role of trace elements in natural or engineered systems will be presented and discussed in the course.
ObjectiveThe students are familiar with the chemical characteristics, the environmental behavior and fate, and the biogeochemical reactivity of different groups of trace elements. They are able to apply their knowledge on the interaction of trace elements with geosphere components and on abiotic and biotic transformation processes of trace elements to discuss and evaluate the behavior and impact of trace elements in aquatic and terrestrial systems.
Content(i) Definition, importance and biogeochemical classification of trace elements. (ii) Key biogeochemical processes controlling the cycling of different trace elements (base metals, redox-sensitive and chalcophile elements, volatile trace elements) in natural and engineered environments. (iii) Abiotic and biotic processes that determine the environmental fate and impact of selected trace elements.
Lecture notesSelected handouts (lecture notes, literature, exercises) will be distributed during the course.
Prerequisites / NoticeStudents are expected to be familiar with the basic concepts of aquatic and soil chemistry covered in the respective classes at the bachelor level (soil mineralogy, soil organic matter, acid-base and redox reactions, complexation and sorption reactions, precipitation/dissolution reactions, thermodynamics, kinetics, carbonate buffer system).
This lecture is a prerequisite for attending the laboratory course "Trace elements laboratory".
701-1681-00LElement Balancing and Soil Functions in Managed EcosystemsO3 credits2GA. Keller
AbstractApplying element balances of agricultural soils and the assessment of soil functions for real applications in computer exercises to design preventive strategies against soil pollution and to support sustainable management of regional agroecosystems also in the context of spatial planning procedures.
ObjectiveThe students learn to critical assess changes in land use management on element cycles in agro-ecosystems and to assess soil services (soil functions). You design solutions for chemical problems in soil protection at the regional scale and learn to assess soil functions using different methods.
ContentThe students apply a regional balance model for Swiss regions in computer exercises and assess major soil functions of agricultural soils. You assess the sustainability of current land use and analyse management options improving nutrient and metal cycling in agro-ecosystems. The students will have the opportunity to calculate specific scenarios regarding land use management and environmental changes. Special focus we be paid on the soil services such as regulation-, production function and soil as habitat, and the assessment of these functions based on soil mapping data.
