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 to the results, chloride concentrations higher than the tolerable limit of a cement raw material would be present in the material about 10-25 cm inward from each discontinuity surface, controlling groundwater flow, located between 170 and 300 m landward from the shoreline at below sea level mining depths of 0-30 m. The estimations suggest that total amounts of dilution required for the contaminated raw material to reduce its concentration level to the tolerance limit with uncontaminated raw material are about 113- to 124-fold for scenario I (13 years of below sea level mining after 30 years of above sea level mining) and about 126- to 138-fold for scenario II (43 years of simultaneous above and below sea level minings).

Development of a geotechnical and geophysical database for seismic zonation of the Ankara Basin, Turkey Koçkar, Mustafa K.; Akgün, Haluk (Springer Science and Business Media LLC, 2008-07-01) Engineering geological and geotechnical site characteristics were assessed and seismic hazard studies performed for the Upper Pliocene to Pleistocene fluvial and Quaternary alluvial and terrace deposits for a site west of Ankara, Turkey. Sediment conditions were determined and a soil profile was characterized by surface geophysical methods. These studies were integrated with existing in-situ characterization studies to create a seismic and geotechnical database for the site. A seismic zonation map of the si...
Environmental geological investigations at the Van open dump site, southeastern Turkey Akgün, Haluk (Springer Science and Business Media LLC, 2000-04-01) This study evaluates the geological, hydrogeological and hydrological conditions at the I waste dump site of the Van municipality in eastern Anatolia, Turkey. A geological map and a three-dimensional view of the project site have prepared. All lithological units exposed at and near the dump site have been determined and their boundary relationships identified. Drainage basin characteristics of the dump site along with the water bearing properties of different lithological units have been assessed. For the r...
Quality assessment of armourstone for a rubble mound breakwater (Sinop, Turkey) Topal, Tamer (Springer Science and Business Media LLC, 2004-10-01) Helaldi is a fishing town in the central Black Sea region where construction of a rubble mound breakwater is being planned. The construction of the breakwater requires good quality durable armourstone. Several laboratory tests are performed for the quality assessment of the two potential armourstone, namely, limestone and sandstone. The quality evaluation of the stones is done on the basis of CIRIA/CUR criteria, saturation coefficient, wet-to-dry strength ratio, and the rock durability index. The quality ev...
Remediation of the geotechnical problems of the Hasankeyf historical area, southeastern Turkey Akgün, Haluk (Springer Science and Business Media LLC, 2003-08-01) The castle, palaces and man-made historical and recent cave dwellings of Hasankeyf will be partly flooded by the reservoir of the Ilisu dam which is planned to be constructed over the Tigris River. Hasankeyf is entirely within the Germik formation which is composed of whitish to light gray and/or beige, medium strong, fresh to slightly weathered, thick to very thick bedded, locally massive, almost horizontal or gently dipping silty, sandy limestone. The major geotechnical concerns in the area consist of the...
Composite landfill liner design with Ankara clay, Turkey Met, İlker; Akgün, Haluk (Springer Science and Business Media LLC, 2005-04-01) This study presents an overview of the geotechnical properties of the clayey soils, referred to as "Ankara clay", at two sites of the Ankara region in an attempt to design a landfill profile composed of a high density polyethylene (HDPE) geomembrane/clay composite liner through the Hydrologic Evaluation of Landfill Performance (HELP) model and the Water Balance Method. The geotechnical properties of the landfill layers along with the water balance factors (i.e., evapotranspiration, precipitation, temperatur...
