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.
