Environmental geological investigations at the Van open dump site, southeastern Turkey

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 rehabilitation of the existing dump site, material availability (clay as a liner, cap, and daily cover material; granular soil as a filter material) has been researched. Based on the geological, hydrogeological, morphological and hydrological conditions of the existing waste dump site, recommendations to minimize its environmental impact are presented.


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. ...
Environmental geological and geotechnical investigations related to the potential use of Ankara clay as a compacted landfill liner material, Turkey
Met, İlker; Akgün, Haluk; Türkmenoğlu, Asuman Günal (Springer Science and Business Media LLC, 2005-01-01)
Clay-bearing Upper Pliocene red clastics and Quaternary alluvial deposits occupy the Ankara basin. The clayey levels of the Upper Pliocene deposits, referred to as Ankara clay, is considered as a source for compacted clay liners due to their low coefficients of permeability and widespread distributions throughout Ankara. This study investigates the geological, geotechnical and mineralogical properties of the founding clayey soils at two sites of the Ankara region. The geotechnical index properties along wit...
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...
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...
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...
