    KADEMELİ POMPALAMA TESTLERİ İLE KUYU PERFORMANSININ ZAMAN İÇİNDE DEĞİŞİMİNİN İNCELENMESİ
    (2018) Türkkan, Gökçen Eryılmaz; Korkmaz, Serdar
    Bu çalışmanın amacı, kademeli pompalama testi ile kuyu performansının yıllar içerisindekideğişimini incelemektir. Çalışmada Neojen Mühendislik tarafından Bursa Küçük Sanayi bölgesindekiserbest akiferde açılan 27 metre derinliğindeki kuyu kullanılmıştır. İlk olarak 2 Kasım 2012 tarihinde biradet kademeli pompalama testi yapılmıştır. Kademeli pompalama testi, aynı kuyuda 23 Mart 2017tarihinde tekrar yapılmıştır. Arazi çalışması sonucu elde edilen kademeli pompalama test verileriHantush-Bierschenk ve Rorabaugh analitik metotları ile çözülüp kuyu performans parametreleri eldeedilmiştir. İki testin uygulandığı tarih arasında kuyu verimindeki ve özgül kapasitedeki değişimincelenmiştir. Kuyu performansının artırılması için öneriler sunulmuştur

    Relationship between hydraulic and geoelectrical parameters for alluvial aquifers in Bursa, Turkey—a case study
    (Springer Science and Business Media Deutschland GmbH, 2021) Eryılmaz Türkkan, Gökçen; Korkmaz, Serdar
    This research aims at analyzing the relationship between the hydraulic conductivity and the formation factor in alluvial aquifers. The study was conducted on the alluvial aquifers within the province of Bursa, Turkey. Field surveys were carried out on 12 different locations each having alluvial formation. Initially, slug tests were applied at the wells and hydraulic conductivity values were calculated by using Bouwer-Rice and Dagan analytic methods. Afterwards, vertical electrical sounding method with Schlumberger array was applied on these locations to obtain apparent resistivity. These values were then converted to real resistivity under IPI2WIN software. Water samples were taken from the wells, and their electrical conductivity values were measured in the laboratory which were converted to water resistivity. Finally, formation factor was calculated as a ratio of real resistivity to water resistivity. The variations of hydraulic conductivity and transmissivity values against the formation factor were examined, and a linear relation was observed. Furthermore, their variations against modified formation factor and modified aquifer resistivity were also investigated and similarly linear relationships were observed. The graphs obtained conform to the results of similar studies in literature and will serve as a guideline for prospective groundwater research in the study area. © 2021, Saudi Society for Geosciences.
