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.

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.
