Animation 1: Example of typical temporal evolution of a conduit pattern in a network with high initial protoconduit heterogeneity (&mu0 = 0.5 mm, &sigma0 = 0.5 mm) and intermediate total maximum recharge rate of Qmax = 10-3 m3s-1. Filled circles represent nodes and rings mark nodes at the recharge side which reached maximum inflow rates of qmax = 5·10-5 m3s-1. Single tubes are shown as arrows indicating the flow direction. The width of the arrows correspond to the logarithm of the apertures and tildes denote regions with turbulent flow. Red colour indicates regions where first-order dissolution kinetics is active.
