Fig. 2From: Modelling of flow through naturally fractured geothermal reservoirs, Taupō Volcanic Zone, New ZealandPossible pathways when fluid tracer particles reach the intersection of two fractures (horizontal and vertical black lines). Green arrows represent inflows to the intersection and the red arrows outflows. The arrow thickness represents magnitude of flows. For any fluid particle entering the intersection, the probability of it leaving by any outflow pathway is proportional to the flow in that pathwayBack to article page
