Thermal fluid circulation around the Karliova triple junction: Geochemical features and volcano-tectonic implications (Eastern Turkey)
(Elsevier, 2019)The Karlıova triple junction (KTJ) in eastern Turkey has been subjected to incremental deformation resulting in complex kinematic and mechanical interactions throughout the upper crust. These interactions have generated ... -
Thixotropy and structural breakdown properties of self consolidating concrete containing various supplementary cementitious materials
(Elsevier, 2015-05)Abstract In this study, thixotropy and structural breakdown of 57 self-consolidating concrete (SCC) mixtures containing various supplementary cementitious materials (SCM) were investigated by different approaches. The ... -
Three dimensional grain boundary modeling in polycrystalline plasticity
(American Institute of Physics, 2018-05)At grain scale, polycrystalline materials develop heterogeneous plastic deformation fields, localizations and stress concentrations due to variation of grain orientations, geometries and defects. Development of inter-granular ... -
Time-dependent physicochemical characteristics of Malaysian residual soil stabilized with magnesium chloride solution
(Springer, 2016-01)The effects of non-traditional additives on the geotechnical properties of tropical soils have been the subject of investigation in recent years. This study investigates the strength development and micro-structural ... -

Tracing the relative distribution of arsenic species in groundwater and its association with soil arsenic levels in the Simav Graben area, Turkey
(Taylor & Francis Group, 2016)A comprehensive hydrogeochemical assessment was conducted in the Simav Plain, Turkey where major health concerns were reported and elevated arsenic (As) levels were previously found. Boreholes drilled in the plain were ... -
Trait-based heterogeneous populations plus (TbHP+) genetic algorithm
(Elsevier, 2009-02)This study developed a variant of genetic algorithm (GA) model called the trait-based heterogeneous populations plus (TbHP+). The developed TbHP+ model employs a memory concept in the form of immunity and instinct to provide ... -
Transport capacity models for unsteady and non-equilibrium sediment transport in alluvial channels
(Elsevier, 2012-08)This study investigates transport capacity models based on different dominant variables-shear stress, stream power, unit stream power, flow discharge, flow velocity, and energy slope - in a model of unsteady and non-equilibrium ... -
Türkiye’de asit maden göllerine Çan (Çanakkale) Havzası’ndan güncel birkaç örnek
(Jeoloji Mühendisleri Odası, 2013)Madencilik faaliyetinin su kirliliğine neden olan birincil kaynağı asit maden drenajı/gölleridir. Peki, bu önemli çevresel sorun Çan havzasında nasıl oluşmaktadır? -
Türkiye’nin yeraltısuyu potansiyeli, yönetimi, kullanımı ve etkileyen faktörler
(TMMOB Jeoloji Mühendisleri Odası, 2015)Türkiye’nin tarımsal, sanayi ve içme suyu ihtiyacı önemli oranda yeraltısularından karşılanmaktadır. Ülkenin kırsal ve kentsel alanlarındaki içme suyunun yarıdan fazlası, ülke tarımsal sulamalarının yaklaşık üçte biri ... -
Two-dimensional finite elements model for boron management in agroforestry sites
(Springer, 2010-01)Agroforesty systems, which are recommended as a management option to lower the shallow groundwater level and to reuse saline subsurface drainage waters from the tile-drained croplands in the drainage-impacted areas of Jan ... -
Two-dimensional finite elements model for selenium transport in saturated and unsaturated zones
(Springer, 2010-10)A two-dimensional finite element model was developed to simulate species of selenium transport in two dimensions in both saturated and unsaturated soil zones. The model considers water, selenate, selenite, and selenomethionine ... -

Types of the scaling in hyper saline geothermal system in northwest Turkey
(Elsevier, 2014-04)Tuzla is an active geothermal area located in northwestern Turkey, 80km south of the city of Canakkale and 5km from the Aegean Coast. The geothermal brine from this area, which is dominated by NaCl, has a typical temperature ... -
The use of cokriging algorithm for arsenic mapping in groundwater systems
(American Society of Civil Engineers, 2012)Accurate mapping of the spatial distribution of arsenic in groundwater is an important but equally difficult task to complete due to a number of uncertainties. Classical univariate interpolation algorithms could sometimes ... -
Use of electrospun fiber mats for the remediation of hypersaline geothermal brine
(Desalination Publications, 2017-02)Geothermal brines display high contents of various metal ions that can adversely affect surface and groundwater resources. Nevertheless, it is possible to sequestrate these metals and use some of them in certain engineering ... -
