Fractured rocksFractured rocksClick on elements of the model or select from the tabs below Fractured rocks (predominantly rocks with secondary porosity)Fractured rocks store and transmit groundwater through fractures within otherwise low permeability rock. Fractures, including joints and faults occur where stress exceeds the rock strength causing the rock to split along its weakest plane. Fracturing of rocks often results from tectonic movement of the Earth’s crust, which can be at a local or regional scale. Fractured rock aquifers may discharge groundwater into channels largely in the lower parts of the landscape supporting fauna and flora communities, ecological processes and delivery of ecosystem services. Channels in upper parts of the landscape usually transmit surface water run-off only. Pictorial conceptual model PDF Additional links
