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 continuation of the nature-friendly appearance of the slopes. To accomplish these tasks, a geological survey was performed. It involved gathering information on rock discontinuities by means of scan-line surveys and collection of rock samples. Furthermore, in situ and laboratory tests were also carried out. The data collected from the field and laboratory test results were used to perform slope stability and rockfall (2-D and 3-D) analyses for different slope conditions along 43 profiles. Based on the analyses, rockfall was found to be the main slope instability problem in the study area. Under the light of these studies, rock removal, drainage, greening (vegetation), filling of caverns, protective wall building and erosion prevention are offered as remedial measures.

Assessment of rockfall hazard around Afyon Castle, Turkey Topal, Tamer; Ozden, Utku Ahmet (2007-09-01) 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 ...
Assessment of rock slope stability for a coastal area near Kuşadası, Aydın, Turkey Kaya, Yavuz; Topal, Tamer; Department of Geological Engineering (2013) The study area, which will be open to tourism in Kuşadası (Aydın), has steep and high cliffs near the Aegean coast. In the area where some slidings and rockfall problems occurred in the past the geological hazards should be investigated and nature-friendly remedial measures should be taken. The aim of this study is to perform engineering geological studies to:(i) search geological hazards, (ii) reveal the slope stability problems, (iii) recommend nature-friendly solutions in order to prevent/minimize the ha...
The impact of economic and social development in Safranbolu Kasap Akpınar, Sibel; Berkman, Gülden; Uzun, Cemile Nil; Department of City and Regional Planning (2011) Safranbolu is among the many other tourism destinations of Turkey practicing sustainable and cultural tourism. Like many tourism centers in Turkey, it had been negatively influenced from economic fluctuations of the 1980s period. However, in spite of other tourism centers, it has not much changed and it has been well protected. The reasons for this protection can be explained that Safranbolu entered the World Heritage List in 1994, and so environmental and sustainable planning approaches are adapted to deve...
Assessment of degradation and stability of a cut slope in limestone, Ankara-Turkey Oztekin, B; Topal, Tamer; Kolat, Çağıl (2006-03-30) Due to the rapidly growing population of the city of Ankara (Turkey) and increased traffic congestion, it becomes necessary to widen the Ankara-Eskisehir (E-90) highway, connecting the newly built areas west of the city to the city center. During widening, several cut slopes were formed along the highway route. As a result, some instability problems (small-sized rock falls/sliding, sloughing, raveling) produced detachment zones along a cut slope in highly jointed, folded and sheared limestone, causing local...
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...
