Abstract: | Summary The results of temperature measurements in six boreholes, drilled near the west shores of the Lake Nasser in the Aswan region
in the Nubian Desert, are reported. Temperature-depth profiles, complemented by thermal conductivity determinations of surface
rock samples, were used to calculate the existing range of heat flow density in the region as 40 ÷ 60 mWm−2, which is consistent with the values from the adjacent areas, reported in the literature. The extrapolated mean annual ground
surface temperatures amount, on the average, to 30°C, which is 3 K higher than the mean annual air temperature in the region. |
