Animation 2: Evolution of the aperture distribution for networks with high protoconduit heterogeneity (&sigma0/&mu0 = 1) and maximum recharge rates of Qmax = 10-3 m3s-1. The animation shows all 30 realisations as well as the mean at t = 0 a and during the simulation time of 30 ka. The evolution of the total inflow Qin &le Qmax is illustrated for all realisations in the inset. Thereby, strong increases of Qin approximately indicate breakthrough times.
