Effective Field Parameters (EFP) Conclusions

  • The results indicate that only a combined modelling strategy considering deterministic and stochastic distribution of effective parameters will allow to perform large-scale predictive modelling

     
  • Such an approach prerequisites the development of a corresponding numerical code

     
  • The up-scaling of the effective parameter set which was evaluated from the small and intermediate scale (e.g. spatial variance and correlation length of permeability and bulk porosity) remains uncertain

     
  • To overcome this lack more large scale hydrogeological investigations are necessary

     
  • Non linear sorption and desorption kinetics combined with chemical reaction characterise the near field of a source, whereas, in the far field the matrix diffusion and the KD concept will ensure a sufficient prediction capability.

25 Years experience
2009 marked a significant milestone in the history of the Grismel Test Site with the running of experiments which have spanned more than 25 years. Read more about the 25 years of scientific exploration in the 25 Years of History at the Gimsel Test Site section. Full details of our 25 year celebration events will be posted shortly


The GTS underground facilities are also available to interested 3rd parties for underground testing and research. The GTS offers cost-effective access to a fully developed, well characterised underground research facility with round the year logistical support - please contact Dr. Ingo Blechschmidt, Head of the Grimsel Test Site, for further details.
