Pretend you are the president of Egypt, a country whose sole source of fresh water is the Nile River. What actions would you take upon learning that Ethiopia, which is upstream from Egypt, had begun building water projects that would restrict the flow of the Nile ...

The Nile River provides a good example of the similarities and differences between sediments from the same river. The common origin of these Nile sediments is confirmed by the high degree of correlation in the elemental compositions between different Egyptian Nile sediment samples (2). 

In most areas of the wadi floor and the low desert area, the Nubian formation is covered by an average of 5-7 m of Pleistocene Nile silts (9). These older Nile sediments represent different episodes in the evolution of the Nile River (10-13), The oldest Nile sediments (called Protonile) in the area, exposed at high (about 125 m above sea level) Pleistocene terraces, were deposited during the Lower to Middle Paleolithic period (10). 

Averages for the 27 bulk samples are given in Table II for some of the elements measured. These averages, called Nile River Sediment Composite (NRSC), are very similar to the averages for modern Nile sediments compiled by Tobia and Sayer (2). This similarity clearly confirms that, other than the variations due to grain size (sand content), the modern Nile silts are quite uniform in composition. 

The macroarchaeometric approach has wide applicability. Climatic studies in the caves of Lascaux, France (8), and Alta Mira, Spain (9), are but two examples. This approach is now particularly useful in studies of the excavated and unexcavated ancient sites of the Nile River Valley because of the recent, accelerated deterioration of many of its monuments. It has already been applied to several ancient Egyptian archaeological sites (10-21). 

Thermal Stability of the Tomb. The self-contained hygrothermograph was left in the tomb of Nefertari in February 1981 for 1 year (34). The temperature and humidity data for the 1-year period were correlated (Figures 5 and 6) with external data taken near the Nile River at Karnak (Figure 4). The Nile River data were obtained in 1981 by M. C. Traunecker, a research chemist with the Franco-Egyptian Centre for Studies of the Temples at Karnak. 

Figure 5 shows average monthly high and low temperatures near the Nile River at Karnak and the monthly average temperatures inside the tomb. The results dramatically confirm the temperature stability of the tomb re-...
