Özet
The monuments on both banks of the Tigris River, known as the "Lower City", in the historical settlement of Hasankeyf, located in the reservoir area of the Ilisu Dam and HEPP Project, and the rocky ground of the "Inner Castle Region of Hasankeyf", known as the "Upper City", above the maximum water level of the dam (+527.86 m), will be directly affected by the water accumulating in the dam lake, while the historical monuments on them will be indirectly affected. Geotechnical investigations, supported by laboratory tests, were carried out to study the characteristics of the rock in the castle area and the rock block on which the Small Palace was built. It was found that the water accumulating in the reservoir would have a detrimental effect on these rocks in the dry state, causing fractures in the rock on the slopes due to the effects of wetting, drying and freezing and thawing. In order to protect the castle's rocks and the cultural heritage on them, natural materials were used to fill the valleys to the south, north and east up to the maximum water level of the dam, reducing the abrasive effect of the water on the limestone rocks and minimising infiltration into the interior regions. As the ground level of the Small Palace (12th-13th century) was lower than the protective embankment around the castle, a reverse dam system was constructed around it to preserve the monument in situ. However, when the water level reached +524.00 m, water seepage from the reservoir accumulated around the monument, causing further deterioration of the restored monument. Due to the potential damage to the architectural and structural integrity of the monument if exposed to water again, an interdisciplinary holistic study was carried out to implement architectural conservation, structural strengthening, and in-situ elevation, resulting in the monument being jacked-up (raised) by 6.00 metres at its current location. © 2024 Gazi Universitesi.
