The major borax producer, Eti Mining Co. of Turkey, planned to construct an export stock site located near the Bandirma Harbor in the northwestern of Turkey. During this construction, some stability problems were encountered. To analyze the stability problems and to assess the engineering properties of soil in the stock site geotechnical investigations were started. As a part of geotechnical investigations one of the most common field tests, the standard penetration tests (SPT), was conducted for soil exploration. In this study, the field is geostatistically simulated to assess the uncertainty associated with the spatial variability of SPT results. Multiple probable realizations of SPT values are generated using sequential Gaussian simulation. Using 122 NSPT data in the borax stockpile site, the characteristics observed in the available data are reproduced in a manner that the heterogeneity of SPT within the field is honored. The estimated NSPT data can also be used for other purposes such as determination of bearing capacity, and estimation of soil strength parameters.

Slope stability analysis of a borax stockpile site Karpuz, Celal (2009-01-01) Stability investigations were conducted for a slope at the back of a borax stockpile site near the Bandirma Harbor in the northwestern Turkey. There was a slope failure at the site causing damage in the concrete sections of the harbour in front. Investigations started with deformation monitoring with an inclinometer. Failure mechanisms were determined with back analysis using method of slices and finite difference models. A combined failure mechanism involving a circular failure surface in the slope and a n...
Evaluation of GRACE based groundwater storage change information at Konya Closed Basin Turkey using remote sensing and in situ measurements Yılmaz, Koray Kamil; Yılmaz, Mustafa Tuğrul (null; 2016-12-12) The Konya Closed Basin (KCB) located in Central Anatolia, Turkey, is the primary grain producer in Turkey and covers an area of approximately 50000km2. The lack of sufficient surface water resources and recently changing crop patterns have led to over-exploitation of groundwater resources and resulted in significant drop in groundwater levels. For this reason monitoring of the groundwater storage change in this region is critical to understand the potential of the current water resources and to devise effec...
Sustainable management of Mogan and Eymir Lakes in Central Turkey Yagbasan, Ozlem; Yazıcıgil, Hasan (2009-01-01) Mogan and Eymir Lakes, located 20 km south of Ankara in Central Turkey, are important aesthetic, recreational, and ecological resources. Dikilitas and Ikizce reservoirs, constructed on upstream surface waters, are two man-made structures in the basin encompassing an area of 985 km(2). The purpose of this study is to quantify groundwater components in lakes' budgets and to assess the potential impacts of upstream reservoirs on lake levels for sustainable management of the system. Available data have been use...
Seismic stratigraphy of Late Quaternary deposits on the continental shelf of Antalya Bay, Northeastern Mediterranean Tezcan, Devrim (2006-09-01) The Late Quaternary sedimentation and structural features of the continental shelf of Antalya Bay (SW Turkey) have been investigated using a single channel high-resolution shallow profiling system. Two seismic units denoted as unit 1 and unit 2 bounded by two major unconformities (R-1 and R-2) have been identified. R-1 and R-2 are type-1 sequence boundaries that formed under sub-aerial conditions during the Late Quaternary sea level lowstands. An acoustic basement (AB) is recognized in the study region; it ...
Evaluation of microplastics removal efficiency at a wastewater treatment plant discharging to the Sea of Marmara Vardar, Suat; Onay, Turgut T.; Demirel, Burak; Kıdeyş, Ahmet Erkan (2021-11-15) Levels, composition and fate of microplastics (MPs) were investigated along different compartments of a secondary wastewater treatment plant (WWTP) with nutrient removal on the northern Sea of Marmara coast (Istanbul, Turkey). When all samples were combined, fibers were found to be the most dominant particles, followed by hard fragments. 500–1000 μm and 1000–2000 μm were the most common size ranges for wastewater and sludge, respectively. Rate of removal differed for sizes and shapes of the particles combin...
