摘要
Naqsh-e-Rostam is known as an ancient periphery which is located in northwest of Persepolis in Fars Province, lran. The oldest relief at Naqsh-e-Rostam is severely damaged and dates to 1,200 B.C.. There is a rock relief thought to be elimate, originally. Four tombs belonging to Achaemenid kings are carved out of the rock face and seven oversized rock reliefs at Naqsh-e-Rostam depict the monarchs of the Sassanid Period. These works are located in orographic mountains which are exposed to the interaction with their surrounding environment. Therefore, existing deterioration as well as erosion process is mainly observed due to climatically conditions and geo-environmental factors which have caused such challenges. Transverse and micro cracks are most kinds of damages that will result in erosion in whole of these works. The focal sources which cause ground cracks have been studied with hydro geological survey. Actually considering the storage volume changing and the calculation of hydrological budget for aquifer, this conclusion drown that the ground crack in this site is the direct result of land subsidence resulting from ground water extraction.
