Characterization of hydrogeological properties of water bearing rocks in a mine site is important for controlling groundwater flow to provide safe operating conditions. This study aims to characterize the groundwater flow in an active mine site in eastern Anatolia. Large diameter pumping wells were drilled in the surrounding carbonate rocks to determine the groundwater flow and boundary conditions along some critical cross-sections. Large diameter wells were also drilled in the mine site for hydraulic testing of the metasediments. Constant rate pumping tests and monitoring of groundwater levels were conducted at each well. Furthermore, twelve diamond core drilling were done in the mine site and a total 33 vibrating wire piezometers were installed at different depths for monitoring pore water pressures. Packer tests were applied on these wells to determine localized hydraulic conductivity of diorite and metasediments at different depths. The results obtained from these tests are used for developing hydrogeological conceptual model for groundwater flow. According to the results, the carbonate unit in the immediate vicinity on the mine site does not contain groundwater in significant amount because of diorite intrusion at the Uzundere-Zangardere area and the metasediments and diorite have low permeability and heterogeneous medium. Also, downward hydraulic gradient was observed in almost all piezometers drilled in the metasediments and diorite and it generally increases with depth. Stable isotope analysis has indicated that the metasediments-diorite are recharged by infiltration from local precipitation.

Hydrogeological and hydrochemical investigation for below-sea-level quarrying at cement raw material site (Kocaeli-Darica, Turkey)
Doyuran, Vedat; Karahanoğlu, Nurkan; Çamur, Mehmet Zeki; Topal, Tamer; Süzen, Mehmet Lütfi; Yesilnacar, Ertan (Informa UK Limited, 2003-01-01)
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 ...
Parameter study on tracer flow test
Aydın, Hakkı; Akın, Serhat (2019-02-13)
Periodic measurement of flow rate in production wells is essential to monitor performance of geothermal wells and reservoir. Tracerdilution method has been introduced as a reliable, cheap and environment friendly technique to measure mass flow rate and enthalpy intwo phase geothermal systems. In this study, Sodium Fluorescein is used to measure liquid phase mass flow rate in a two phase productionline and in a single phase liquid injection line. The study includes the effect of flow regime and flowrate on t...
Geotechnical Assessment of Compacted Sand Bentonite Mixtures to be Utilized in Underground Nuclear Waste Repositories and Barrier Design
Akgün, Haluk; Koçkar, Mustafa Kerem (2016-07-01)
This study assesses the mechanical and hydrological performance of compacted sand bentonite mixtures to be utilized in sealing underground nuclear waste repositories. In order to assess the performance of this material and to obtain an optimum sand bentonite mixture, a variety of laboratory tests, namely, compaction, falling head permeability, swelling, unconfined compression and shear strength tests were performed on sand bentonite mixtures possessing bentonite contents ranging from 5% to 15%. Sand bentoni...
Spatial Variability In Seepage Flow Through Earth-Fill Dams
Çalamak, Melih; Yanmaz, Ali Melih; Kentel Erdoğan, Elçin (2013-10-10)
Dams made of earth materials show highly variable hydraulic properties because of uncertain nature of the earthen embankment. Uncertain nature of soil properties may result in variations in flow fields in embankment dams. Determination of seepage characteristics of a dam is crucial since it directly affects the stability. Underestimation of the seepage may lead to catastrophic failures of dams. In this paper, uncertainty in the hydraulic conductivity of the embankment is evaluated through Monte Carlo simula...
Seismic Performance Evaluation of Concrete Gravity Dams by Using Pseudo Dynamic Testing and Simulations
Aldemir, Alper; Binici, Barış (null; 2017-11-24)
Dams are one of the mostimportantinfrastructure components servingfor water storage and energyproduction.Experimental studies on the seismic response of concrete gravity dams are scarce due to the complications regarding thelargescaleof dams and their interaction with the reservoir. This study presents the results of recent novel pseudo-dynamic dam tests (PSD) along with the nonlinear finite element simulations of the specimens. The test specimens were 1/75 scaled version of the highest ...
