Text of Note

Numerous remnants of major old and ancient civilizations throughout the world are now undergoing rapid and accelerated degradations. Because many of the monuments are located in developing countries that face a multitude of new and unexpected challenges and because basic physicochemical processes are normally site-specific, the reasons for these deteriorations are often complex and poorly understood. In this dissertation, degradation of the Karnak Temple Complex is studied using computer modelling of the water flow through the Karnak system from the irrigated fields towards the Nile. The Karnak Temple Complex which occupies an area of approximately one square mile on the bank of the river was constructed over 2000 years starting about 2000 B.C. and is one of the most important archaeological sites in the world. The conductivity function in the unsaturated region was calculated using the following equations: S = (1 + usd\vert \alpha\psi\vert\sp{\rm n})\sp{\rm -m}usd where usd\psiusd is the suction potential, n and m are interdependent constants and K = Ksat S (1 S where S is the degree of saturation. It is concluded that the principal cause for recent deterioration of Karnak is the evaporation of saline groundwaters under the Temples which leads to the deposition of large quantities of salts at the foundations of the monuments. The decay of the monuments is therefore progressive, rapid and cumulative. (Abstract shortened by UMI.)
