    Anthropogenetically triggered landslide factors of the Varyant landslide area at Buyukcekmece, NW Turkey
    (Gebruder Borntraeger, 2006) Ertek, T. A.; Erginal, A. E.
    Since early 1950s many natural conditioning factors and interference have given rise to landslides near heavily populated settlement areas at the western part of Istanbul, NW of Turkey. Both human involvement and heavy rainfall have a great impact as triggering factors over the Varyant landslide area (VLA). The onset of the landslide activity ill VLA began in 1950's after the construction of E-5 motorway, at the east of Buyukcekmece Lake. A linkage way to E-5 motorway was built near the drainage divide of Cakmakli Creek catchment has already been causing some disturbance to the slope stability. Excavation activities were carried out in order to get materials for building of the Buyukcekmece Dam, do form one of the important drinking water sources of Istanbul. A great amount of materials were derived from the accumulation zone of the above-mentioned old landslide area with nearly 1 km length and the excavations heightened the slope failures. Following the construction of the Buyukcekmece Dam in 1989, a water pipe-line was installed within a landslide body, resulted in some new slope movements. Finally, a pipe-line-induced destructive landslide occurred on 2(nd) February 2000, causing a great economic damage of nearly US $ 5.5 million. In the present study, both natural conditioning factors and human-induced processes creating slope failures have been discussed. Considering all effective factors, the human interference and rainfall impact have together been evaluated as two dominant triggering factors.

    Investigation of land use and coastline changes on the Kepez delta using remote sensing
    (2008) Akbulak, C.; Erginal, A. E.; Gönüz, A.; Öztürk, B.; Çavuş, C. Z.
    Bu çalışma, hava fotoğrafları ve uydu görüntüleri temel alınarak, 1962-2005 yılları arasındaki periyotta, Kepez Deltasındaki arazi kullanım özellikleri ve kıyı çizgisi değişimlerini ortaya koymaktadır. Kepez kasabasının nüfusu, 1935-2000 yılları arasında hızlı bir artışla 24 kat büyümüş, bunun sonucunda yerleşim alanları da verimli tarım arazileri üzerine doğru (yaklaşık 23 kat) genişlemiştir. Tarım alanlarını ve kıyı ekosistemini büyük ölçüde tehdit eden ikincil konutlar ise, sahanın güneyindeki Dardanos mevkiinde, 1980’li yıllardan itibaren yayılış göstermektedir. Son 43 yıl içinde, kıyı zonundaki doğal morfodinamik süreçler ve beşeri etkenlerin etkisiyle kıyı çizgisi değişimleri meydana gelmiştir. Bu değişimler kıyının farklı kesimlerinde, yaklaşık 40 m’lik progradasyon (sediman birikimi) ve 20 m’lik kıyı gerilemesi (kıyı erozyonu) ile karakterize edilmektedir.

    LUMINESCENCE DATING OF PREHISTORIC SITE OF SMINTHEION (GULPINAR) IN NW TURKEY
    (Univ Agean, Dept Mediterranean Stud, 2010) Kiyak, N. G.; Takaoglu, T.; Erginal, A. E.; Ozcan, H.
    This study aims to place the prehistoric settlement of Smintheion in northwestern Turkey in its temporal setting on the basis of the dating of the quartz from pottery and sediments collected from the site employing Optically Stimulated Luminescence and Thermoluminescence techniques. The site belongs to the problematic Middle Chalcolithic period in western Anatolia. This period represents a cultural upheaval in western Anatolia as it has a completely different material culture when compared to that of the preceding Early Chalcolithic period. The pottery and sediment samples were collected from two different locations of the Middle Chalcolithic settlement at Smintheion for dating study. The fact that this examined settlement is represented by a single cultural level provides an opportunity to obtain secure and reliable dates for the settlement. Results of this study show that the site can be dated to a period between 4800 and 4500 B.C.
