Evaluation of Tracer Transport Into a Tunnel by Various Numerical Models
Popis výsledku v původním jazyce
Paper in proceedings without ISBN on memory media, 4 pages: We study the water flow in fractured granite between the surface and the tunnel, using a numerical model to interpret data from natural tracers (described in a separate paper by Sanda et al. [1]). The main features are the distinction of the shallow permeable zone and a permeable fracture/fault from remaining compact rock is included in the 3D model variant. First, we solve the pulse transport and compare the mean residence time with the lumpedparameter model results (both the stable isotopes 2H and 18O and the 3He/3He data). Second, we input and fit the real stable isotopes concentration sequences in the surface and the tunnel respectively, for the shallow parts of the tunnel. In both cases,mobile water volume (porosity of permeable structures) is estimated together with hydraulic parameters from the inflow rates.
