The Afyon Castle is a tourist destination and a historical site in the City of Afyon in Turkey. The Castle is located on a steep hill, with a height of 226 m. In close proximity to the Castle there are settlements. The hill consists of trachitic andesite. The rock contains columnar joints and flow layering. Owing to these discontinuities, blocks of varying sizes had fallen down. The settlement areas near the Castle are now in danger because of the rockfall risk. In this study, rockfall analysis was carried out along nine profiles of the hill. Fall-out distance, bounce height, kinetic energy and velocity of the rocks along each profile were investigated. The results of the analyses were evaluated, and the areas delineated as susceptible to rockfall risk are highlighted. Remedial measures including rock bolts and protective fences were suggested on the basis of the field observations and the rockfall risk evaluation.

Assessment of deterioration and collapse mechanisms of dolomitic limestone at Hasankeyf Antique City before and after reservoir impounding (Turkey) Topal, Tamer (2016-01-01) The Hasankeyf Antique City located in southeastern Anatolia (Turkey) includes several historical heritages and man-made caves. It is mainly located in dolomitic limestone. The city will be partly under water after reservoir impounding of the Ilisu dam, and the limestone will be subjected to cyclic processes such as wetting-drying and freezing-thawing. Although a new town is formed and part of the city is transported to a nearby area, this cannot be done for many existing historical and cultural values at th...
Assessment of environmental and engineering geological problems for the possible re-use of an abandoned rock-hewn settlement in Urgup (Cappadocia), Turkey Ulusay, Resat; Gokceoglu, Candan; Topal, Tamer; Sonmez, Harun; Tuncay, Ergun; Erguler, Zeynal Abiddin; Kasmer, Ozgu (2006-07-01) The Cappadocia Region of Central Anatolia having a very distinct culture is one of the attractive touristic sites of Turkey due to its spectacular and unique landforms and historical heritages. In this region, the structures carved into thick to massive tuffs survived and kept their original integrity for a number of centuries. Environmental and anthropological factors at the Cappadocia Region have been the main reasons for extensive subsurface and multi-purpose use in the past and present. In addition, the...
Evaluation of rock slope stability for a touristic coastal area near Kusadasi, Aydin (Turkey) Kaya, Yavuz; Topal, Tamer (2015-09-01) The study area, which will be open to tourism in Kusadasi (Aydin), has steep and high cliffs on the Aegean coast in Turkey. Flysch is the main lithological unit and consists of alternating sandstone-claystone-marl sequences. Some sliding and rockfall problems have occurred in the area in the past, so potential geological hazards need to be investigated to ensure the safety of tourists. The aim of this study is to mitigate geological hazards by recommending engineering solutions, which will ensure the contin...
Contrast Behavior of Sandstone from Mount Nemrut (Adiyaman-Turkey) After the Accelerated Weathering Tests Topal, Tamer (2014-09-19) Mount Nemrut Tumulus is one of nine sites in Turkey inscribed into the UNESCO World Heritage List. Geological investigation was carried out in the field between 2006 and 2009 around Mount Nemrut and its close vicinity. There are statues and horoscopes made of sandstone. The Lower Miocene sandstone covers an area of approximately 0.46 km2. The sandstone seen at Mount Nemrut is gray, thin-to medium bedded, moderately weathered, weak to moderately strong. Bedding planes are detached both in the field and on th...
Emphasizing local features for effective environmental education Environmental attitudes of elementary school students living in ancient Halicarnassus Turkey Bas, Meltem; Teksöz, Gaye; Ertepınar, Hamide (2011-01-01) Ancient Halicarnassus, the site of the Mausoleum of Halicarnassus, has become famous since the 1980s as one of the major tourism centers of Turkey. Although the contribution of Ancient Halicarnassus to Turkey’s economy increases as the number of tourists visiting the area increases, the area's historical, cultural and environmental values have been depleted. Ancient Halicarnassus still hosts the Mausoleum, but it does not get enough care it deserves as far as sustainable use of natural resource is concerned...
