Influence of a Soil Pipe Network on Catchment Hydrology
Water flow in natural soil pipes (pipe flow) is recognized as a potentially significant mechanism in subsurface flow contributions to stream flow (Whipkey, 1969; Jones, 1975). It is a phenomenon known to occur in both humid and arid climates and is not restricted to a particular soil type. Enough measurements of pipe flow under different environmental conditions have not been made to actually quantify the significance of pipe flow in generating contributions to storm and drought hydrographs. However, there are a few reports on the limited measurements that have been made (Jones, 1975; Jones, 1978; Gilman and Newson, 1980).
