Abstract
The INTRAVAL test case 4 is based upon the Stripa 3-D experiment performed at the Stripa mine in central Sweden. This 3-D experiment provides a unique opportunity to examine tracer transport through a three dimensional block of granite above the drift, containing the boreholes. This report summarizes the modelling and model validation programmes of the four project teams who have analyzed the available data as part of INTRAVAL. The individual modeling approaches taken provide a range of analyses that are both complementary and stimulating. The experiment was over a large spatial scale and enabled the collection of data on tracer transport through a three dimensional block of fractured rock. The underlying fracture geometry was also investigated against the background of the observed flow rates prior to the selection of injection sites. The subsequent tracer breakthrough data was highly heterogeneous and represented a formidable challenge to the validity of existing conceptual and mathematical models for tracer migration and dispersal within fracture rock systems. Four project teams employed four diverse approaches: numerical simulations/synthesis; uniform continuum models investigating dispersive effects due to a range of possible processes; models based upon the variable aperture concept analysing the dispersive effects of local fluctuations in fracture
