A research has been carried Out to investigate the effects of below sea level mining on the cement raw material quality of a limestone quarry located adjacent to the shoreline near Darica-Kocaeli-Turkey. Field studies involved rock mass characterization through discontinuity surveys performed at the working benches of the quarry as well as on the core samples, monitoring of groundwater levels, performance of water pressure tests, and in-situ hydrochemical measurements. Hydrogeological data suggest that the carbonate sequence forms a poor unconfined aquifer having hydraulic conductivity values ranging between 10(-6) m/s and 10(-8) m/s. In the quarry, water seepages can only be observed at the shear zones. Electrical conductivity profiles taken from the boreholes located at various distances from the shore line indicated the present position of the salt water wedge.

Stability Charts for the Collapse of Residual Soil in Karst DRUMM, Eric C.; Akturk, Oezguer; Akgün, Haluk; Tutluoğlu, Levend (American Society of Civil Engineers (ASCE), 2009-07-01) Collapse of the residual soil over bedrock cavities often occurs during construction in karst terrain, particularly when the thickness of the residuum is reduced during excavation. Even if an estimate of the strength of the residual soil is known, uncertainty with respect to the size/geometry of the subterranean voids makes a detailed analysis difficult, and straightforward methods to check the stability are needed. In this study, numerical analyses were performed to develop a stability chart expressed in t...
Levels and sources of polychlorinated biphenyls in Ankara creek sediments, Turkey Ozyurek, Nazan Akduman; Gedik, Kadir; Sıltu, Esra; İmamoğlu, İpek (Informa UK Limited, 2013-06-01) The spatial distribution, degree of pollution and major sources of polychlorinated biphenyls (PCBs) were evaluated in surficial sediments of Ankara Creek, located in the capital of Turkey and serving as one of the tributaries in the third largest watershed in Turkey. Sediment sigma PCB concentrations analyzed on Aroclor and congener basis (seven indicator congeners) range from 5.5 to 777.6ng g1 and 3.7 to 743.3ng g1 dw as Aroclor and congener based concentrations, respectively. High concentrations of sigma ...
Contamination of the cement raw material in a quarry site by seawater intrusion, Darica-Turkey Çamur, Mehmet Zeki (Springer Science and Business Media LLC, 2008-02-01) The open pit mining nearby shoreline is planned to be extended into below sea level in order to use additional reserves of the cement raw material (marl). The raw material is currently contaminated by seawater intrusion below a depth of 20 m up to the distance of 90 m from shoreline. Seawater intrusion related contamination of the material used for the cement production was investigated by means of diffusion process for the future two below sea level mining scenarios covering 43 years of period. According t...
Slope stability assessment of a re-activated landslide on the Artvin-Savsat junction of a provincial road in Meydancik, Turkey Topsakal, Ebru; Topal, Tamer (Springer Science and Business Media LLC, 2015-03-01) The purpose of this study is to determine the most suitable remediation techniques for an active landslide area in Turkey, using a geological engineering assessment of a re-activated landslide that occurred during the construction of the Artvin-Savsat Junction on the Meydancik Provincial Road, at Km: 12 + 200. For this, the geotechnical parameters of the mobilized geological material-which is colluvium along the sliding surface-were determined by back analyses of the landslide at three geological sections. ...
Measurement and evaluation of the hydrodynamics and secondary currents in and near a strait connecting large water bodies - A field study Gueler, Isikhan; Yueksel, Yalcin; Yalçıner, Ahmet Cevdet; Cevik, Esin; Ingerslev, Christian (Elsevier BV, 2006-09-01) The straits connect two large water bodies show highly strong and stratified currents related to meteorological, morphological and hydrodynamic conditions. In some cases, spatial and temporal changes of the stratified currents and their thickness, direction and magnitude are so complex. This complexity directly affects the circulation pattern in the region, water exchange between both ends of the straits and migration of fish species. In order to understand general characteristics of this kind of straits an...
