This study presents the dewatering assessment of a marl quarry with the future pit lake level predictions. The objectives of the study were; (1) to determine the dewatering requirements that would allow for the continuation of the quarrying operations in the deeper parts of the quarry, (2) to design an optimum dewatering system compatible with the site hydrogeological conditions and quarrying plans, (3) to assess the environmental impacts of dewatering on the local water (surface and ground water) resources and users, and (4) to predict the future pit lake level and flooding period for different meteorological conditions. To these ends, previous investigation reports and maps have been compiled and reviewed and field investigations have been conducted. During the field investigations pumping and observation wells were drilled and installed. After installation, in situ tests were conducted to determine aquifer parameters. It was found that properties of the material is conducive to the dewatering activities that will be necessary for the deepening of the open pit of the marl quarry. A groundwater model was developed based on the field data gathered. According to this model dewatering trenches will be needed to dewater the pit. The model predicted that operating these dewatering trenches would create an elongated cone of depression that will sufficiently lower the groundwater table so that quarrying operations can proceed. Lowering of the water table may produce a negative impact on groundwater resources within the aerial extent of the cone of depression. This potentially negative impact was investigated with model simulations and has been found that the impact to the resources would be negligible. Three scenarios were evaluated as possible dewatering discharge disposal solutions. The preferred scenario included the discharge of this water to the stream, which is

Geoarchaelogical investigation of central anatolian caravanserais using gis Ertepınar Kaymakcı, Pnar; Toprak, Vedat; Department of Geological Engineering (2005) This study comprises analysis of geological, geomorphological constraints that played role in the site selection of caravanserais. In order to do this, 15 caravanserais located along a route from Nevşehir-Aksaray-Konya to Beyşehir were used. The data used in the study include a caravanserai database, lithological maps, and digital elevation model of the area. GIS analyses performed in the study are proximity, visibility, and probability distribution (PDA). The first step is the generation of the ancient tra...
Hydrogeochemical evaluation of heavy metal loadings to waters and sediments by leachate: A case study from the Golbasi waste disposal site, Ankara, Turkey Canpolat, F; Camur, MZ; Yazıcıgil, Hasan (Informa UK Limited, 2001-10-01) At sites of groundwater contamination. predictions of contaminant behavior and evaluation of remedial strategies depend on identification and characterization of the geochemical processes affecting contaminant migration. Heavy-metal loadings to waters and sediments by leachate from the Golbasi waste disposal site in Ankara, Turkey, have been evaluated quantitatively using hydro-geochemical modeling. The groundwater of the waste disposal area. characterized by high concentrations of Ca, K, Cl, Cd, Pb, Zn, Cu...
Geotechnical rock-mass evaluation of the Anamur dam site, Turkey Ozsan, A; Karpuz, Celal (Elsevier BV, 1996-03-01) This paper describes a feasibility-level geotechnical evaluation carried out at Anamur dam site, in terms of stability analysis of dam foundation, excavation slopes and a diversion tunnel. The proposed Anamur dam will be built across the Anamur river on the Alanya metamorphic series which consists of phyllite, schist and slate units at the site. Geotechnical investigations included drilling for core, pumping tests, sampling for laboratory testing, and a detailed discontinuity survey.
An analysis of the relationship between settlements, water resources and rock types in Çankırı province Bayraktaroğlu, Cüneyt; Toprak, Vedat; Department of Geological Engineering (2005) This study introduces an approach that seeks a possible relationship between settlement locations, water resources and rock types. The method is applied to Çankiri province (central-north Anatolia) which covers approximately an area of 8380 km2. Three main data sets used in this study. These are settlement, water and rock type data.The methodology of the study is composed of five steps. The first step is the conversion of all water data into a standardized point data. Total number of point data for water is...
GIS based geothermal potential assessment for Western Anatolia Tüfekçi, Nesrin; Süzen, Mehmet Lütfi; Department of Geological Engineering (2006) This thesis aims to predict the probable undiscovered geothermal systems through investigation of spatial relation between geothermal occurrences and its surrounding geological phenomenon in Western Anatolia. In this context, four different public data, which are epicenter map, lineament map, Bouger gravity anomaly and magnetic anomaly maps, are utilized. In order to extract the necessary information for each map layer the raw public data is converted to a synthetic data which are directly used in the analy...
