1 Warner, J. W.; Gates, T. K.; Fahim, W.; Ibrahim, M.; Awad, M.; Ley, T. W. 1984. Hydraulic conductivity and vertical leakage in the clay-silt layer of the Nile alluvium in Egypt. Cairo, Egypt: Egypt Water Use and Management Project. ix, 88p. (EWUP technical report no.60)

Data were collected from three sites in Egypt's Nile Valley and Delta to determine saturated hydraulic conductivity in the clay-silt water table aquifer and vertical leakage to the underlying Nile River sands. Auger hole test results gave saturated horizontal hydraulic conductivities of 1103 mm/day for Abyuha in the Middle Nile Valley, 197 mm/day for Beni Magdul near Cairo, and 103 mm/day for Abu Raya in the northern Delta. Auger hole, permeameter, and consolidation tests resulted in saturated vertical hydraulic conductivities of 0.03 to 4.9 mm/day for Abyuha, 0.03 to 0.87 mm/day for Beni Magdul, and 0.03 to 0.45 mm/day for Abu Raya. Several methods were used to determine vertical leakage: Darcy's law, water table decline, water budget, pumping test, and analytical solution. Average vertical leakage rates were very low for each site: 0.59 mm/day in Abyuha, 0.64 mm/day in Beni Magdul and 0.47 mm/day in Abu Raya. These results indicate poor natural drainage characteristics in the clay-silt layer which contribute to the high water table conditions observed throughout Egypt.
