A methodology providing new insights into the flow patterns of karst aquifers: an example from SW Türkiye Maramathas, Athanasios; Katsanou, Konstantina; Sağır, Çağdaş; Baba, Alper; Lambrakis, Nikolaos (2024-10-01) This paper presents a new and innovative methodology for the investigation of karst systems using spring discharge. The behaviour of springs in phase space is investigated by plotting the measurements of spring discharge v...
Numerical and Experimental Approach to Evaluate Microplastic Transport in Saturated Porous Media Okutan, Hande; Sağır, Çağdaş; Kurtuluş, Bedri; Özmen, Hasan Burak; Pekkan, Emrah; Razack, Moumtaz; Le Coustumer, Philippe (2024-09-01) Under varying flow rate conditions, the transport and retention of polydisperse microplastics (MPls), with an average particle size of 16 ± 6 µm, were investigated in saturated porous media. First-order reversible and irre...
Block Rotations in NW Iran in Response to the Arabia-Eurasia Collision Constrained by Paleomagnetism Niknam, Ali; van der Boon, Annique; Rezaeian, Mahnaz; Kaymakcı, Nuretdin; Langereis, Cor (2024-08-01) Northwest Iran is a seismically active region dominated by NW-SE trending strike-slip faults, such as the North Tabriz and Qosha Dagh faults, and smaller NNE-SSW striking faults. The Bozgush Mountains are shaped by these f...

Classification and modification of slake durability test for different types of rocks Ersöz, Timur; Topal, Tamer (2024-04-01) Rocks exposed to atmospheric conditions are subjected to weathering processes driven by numerous factors especially precipitation. The slaking behavior attributed to water-induced weathering particularly affects rocks cont...
A Novel VS30 Prediction Strategy Taking Fluid Saturation into Account and a New VS30 Model of Türkiye Okay, Hakan Bora; Özacar, Atilla Arda (2024-04-01) The averaged shear-wave velocity of the top 30 m (VS30) is widely used in earthquake engineering as a proxy to represent site responses. However, the spatial availability of measured VS30 is rather limited, and, so far, a ...
İzmir Kent Merkezinin Toprakları İçin Sağlık Riski Değerlendirmesi Kılıç, Atilla; Toksoy Köksal, Fatma (2024-03-08) The geochemical characteristics of soil horizons and specific rock types in the vicinity of Izmir city center were studied for interpretation to see the possible health risk associated with geogenic control. The purpose of...
