The purpose of this study is to assess potential impacts of leakage from the base of TSF on groundwater quality both in operational and post-closure period of a mine site in western Turkey. For this purpose, analytical and 2-D and 3-D numerical models are used together. The potential leakage rate of sulphate-bearing solution from the base of TSF is determined from analytical model. 2-D finite element models (SEEP/W and CTRAN/W) are used to simulate unsaturated flow conditions and advective-dispersive contaminant transport below the TSF under steady-state and transient conditions for the operating period. The long-term impacts of leakage from the base of TSF on groundwater resources are evaluated by 3-D numerical groundwater flow (MODFLOW) and contaminant transport models (MT3DMS). The model results suggest that sulphate-bearing solution leaking from the base of TSF can reach water table in about 290 years. Hence, during the operational period (i.e. 21 years), no interaction is expected between the solution and groundwater. Moreover, long-term simulation results show that about 500 years later, the sulphate concentration in groundwater will be below the maximum allowable limits (i.e. 250 mg/L).

Groundwater vulnurability assessment with DRASTIC method : a case-study on Kırıkkale Plain, Turkey
Büyükdemirci, Ahmet Hakan; Önder, Halil; Department of Civil Engineering (2012)
The objective of this study is to achieve vulnerability assessment of the groundwater by using DRASTIC Method which is developed by United States Environmental Protection Agency (USEPA). It is most commonly used overlay and index method all over the world. Evaluation of groundwater vulnerability would be performed by using computer programs which are based on Geographical Information System (GIS) in order to facilitate data management and spatial analysis. The term vulnerability, that is used in this study,...
Assessment of dewatering requirements for Çaldağ nickel mine in Western Turkey
Cankara, Çiğdem; Yazıcıgil, Hasan; Department of Geological Engineering (2011)
The purpose of this study is to assess the dewatering requirements of planned open pit nickel mining at Çaldağ Site in Western Turkey. Dewatering is required for safe and efficient working conditions and pit wall stability. With this scope, a groundwater model of the study area is developed and used to predict the dewatering rate. The methodology mainly involves data collection, site hydrogeologic characterization and development of conceptual model, followed by construction and use of a groundwater model t...
Settlement behaviour of concrete faced rockfill dams : a case study
Özkuzukıran, Rıza Savaş; Özkan, M. Yener; Department of Civil Engineering (2005)
In this study settlement behaviour of Kürtün dam, which is the first concrete faced rockfill dam in Turkey, is investigated. Two dimensional plane strain finite element analyses are carried out in order to determine the total stresses and displacements during construction and reservoir filling conditions. Hardening soil model is used in order to represent the non-linear, inelastic and stress dependent behaviour of rockfill material. Material model parameters are selected mainly referring to the previous stu...
Hydrogeological characterization of the Alpu coal mine exploration site in Eskişehir-Turkey
Çatak, Mert Onursal; Yazıcıgil, Hasan; Department of Geological Engineering (2016)
The purpose of the study is to characterize the hydrogeological conditions at the Alpu Coal Mine Exploration Site which is located in the Eskisehir Province in Turkey. This is required to provide baseline hydrogeological information before environmental impact assessment of the planned mining operations can be done. The characterization studies included hydrogeological and hydrochemical analysis of groundwater and surface water. The spatial and temporal variations in groundwater levels are determined by mea...
Modeling of lithology induced chemical anomalies in the aquifer systems of the Kazan Trona deposit area, Ankara, Turkey
Çamur, Mehmet Zeki; Yazıcıgil, Hasan (2008-04-01)
The study was carried out in order to investigate existing hydrogeochemical relationships between groundwater environment and geological units in the Kazan trona deposit area, Ankara, Turkey. Evaluations indicate that concentrations of alkalinity, boron, chloride and sodium in the upgradient groundwater of the Eocene sedimentary units gradually increase toward downgradient by the interactions of saline minerals (searlesite, shortite, northupite and pyrite) present in the secondary structures (microfractures...
