Uncertainty of the Hydraulic and Transport Model Based on the Tunnel Inflow Observation

Popis výsledku v původním jazyce

Water inflow data were studied in a 2600m long compact-granite tunnel of the maximum depth of 150 m located in Bedrichov (the Jizera Mountains, the Czech Republic). The aim of this study was to determine granite massif properties with focus on the inflowdata assimilation and the uncertainty analyses (the inflow was measured by two different methods in the collection canal). There are 4 models used in this study. Two numerical models, (1) two-dimensional and (2) three-dimensional one , where inverse calibration of hydraulic conductivity was performed. The concentration of the natural tracers 18O and 2H from four discharges was used for modeling of transit time using (3) lumped-parameter model. Artificial pulse of concentration in the (4) advection model in the same configuration like the two-dimensional model was used for estimation of transit time. Results of these different models were compared with each other and give the range of hydraulic conductivity similar to values typical for
