Investigating the age distribution of fracture discharge using multiple environmental tracers, Bedrichov Tunnel, Czech Republic

Popis výsledku v původním jazyce

The transit time distribution (TTD) of discharge collected from fractures in the Bedrichov Tunnel, Czech Republic, is investigated using lumped parameter modelsand multiple environmental tracers. We utilize time series of d18O, d2H and 3H along with CFC measurements from individual fractures in the Bedrichov Tunnel to investigate the TTD, and the uncertainty inestimated mean travel time in several fracture networks of varying length and discharge. We compare several TTDs,including the dispersion distribution, the exponential distribution,and a developed TTD which includes the effects of matrix diffusion. The effect of seasonal recharge is explored by comparing several seasonal weighting functions to derive the historical recharge concentration. Weidentify best fit mean ages for each TTD by minimizing the error-weighted, multi-tracer chi-2 residual for each seasonal weighting function. We use this methodology to test the ability of each TTD and seasonal input function to fit the observed tracer concentrations, and the effect of choosing different TTD and seasonal recharge functions on the meanage estimation.
