Thèmes de recherche

Basic Issues: Transport of water, solutes, gas and heat in (real) soils :

- strong emphasis on conducting controlled field experiments that are based on clearly defined research questions
- adapting and developing models that are suitable for describing those features that govern field-scale transport processes
- key issue for the future is the dynamics of soil and rock structures and their influence on transport in those media

Environmental Issues :

- management practises and physical soil status
- mobility of chemicals in the vadose (unsaturated) zone
- transport phenomena in fractured rock as related to nuclear repositories

Methodological Issues :

- high resolution TDR-technology. Scientific partner: W. Bächtold, Microwave Electronics, ETH Zürich
- image analysis and quantification of dye tracer distributions in soils. Scientific partners: K. Seidel and G. Gerig, Image Science, ETH Zürich; H. van den Bergh, Air and Soil Pollution, EPF Lausanne

Over the past decades his research interest has revolved around the transport of water, solutes, gas and heat in real soils with a strong emphasis on conducting controlled field experiments that are based on clearly defined research questions. He has focussed equally on the development of instrumentation and models. Instrumentation techniques he has furthered include high resolution TDR-technology and image analysis techniques for quantifying dye tracer distributions in soils. Modelling concepts he has developed or contributed to represent features that govern field-scale transport processes including the dynamics of soil and rock structures.

Prix et récompenses

EGU John Dalton Medallist 2004 "for his fundamental contributions to the understanding of transport processes in soils at the field-scale."
