Inherited drainage - paleochannels and preferential groundwater flow
It is suggested that in a localized remnant of Kalahari sand at Dufuya, central Zimbabwe, groundwater flows in an integrated pattern inherited from the paleochannel network of the underlying gneiss. Contact springs occur at discrete localities along the Kalahari sand/gneiss boundary and are associated with spring sapping and land surface subsidence. Subsidence is presumed to be due to preferent...
متن کاملConnectivity due to preferential flow controls water flow and solute transport at the hillslope scale
Understanding the major controls on water flow and solute transport at the hillslope scale remains a major topic of research despite numerous hillslope experiments at different sites around the world. For example, the influence of lateral preferential flow due to pipes or macropores in the subsurface flow is still unresolved. Experiments show the often paradoxical finding of fast entry of event...

متن کاملSolute transport along preferential flow paths in unsaturated fractures
Laboratory experiments were conducted to study solute transport along preferential flow paths in unsaturated, inclined fractures. Qualitative aspects of solute transport were identified in a miscible dye tracer experiment conducted in a transparent replica of a natural granite fracture. Additional experiments were conducted to measure the breakthrough curves of a conservative tracer introduced ...
