For earth dams, generally granular soil is used as a filter material. However, in recent years, in Turkey, there are difficulties in finding granular filter material which has the desired properties, in sufficient amounts and at close distances to the project area. Therefore, alternative filter materials are being considered instead of granular soil. The use of geotextile filters is preferred in many different construction and infrastructure applications, in particular for the protection of the environment and natural resources, sustainability, reducing the carbon footprint of the project and reduction of cost. Geotextile filters can be used to provide filtration in chimney drains, trench drains, blanket drains, and heel drains. There are two important and conflicting criteria a filter material should satisfy: (1) the permeability criterion, (2) retention criterion. The filter should have small opening size so as not to allow the transfer of the fine particles with the water flow, but should also have enough and large opening size to be permeable enough and allow free water flow. In this study, a comparative evaluation of the filter criteria in the international standards for granular filter and geotextile filter is carried out.

An experimental study on geotextile-soil filter system Gül, Sevil; Huvaj Sarıhan, Nejan; Department of Civil Engineering (2020-10-21) Filters have been used in earth structures such as retaining walls, earth dams etc. to prevent the loss of particles induced by seepage of water. Traditionally granular filter materials are used, however, they are becoming more difficult to obtain and transport to the construction site and transportation of granular material raise the cost of construction and carbon footprint of the project. Therefore, the need for an alternative filter material arises, and geotextiles can be considered as one of the best o...
Replication of geomembrane interfaces using 3d printing (fused deposition modelling) technique Uragan, Semkan; Huvaj Sarıhan, Nejan; Department of Civil Engineering (2020-12-22) Geomembrane – soil interface is a critical consideration in geotechnical engineering applications such as liners and covers in landfills, canals or mine tailing dams. In some cases, lack of sufficient shear strength in these interfaces leads to poor performance, uneconomical design (such as requiring a longer geomembrane in an anchor trench), or may even lead to failure. To eliminate such problems, geometrical features known as asperities (or protrusions) are used on the geomembrane's interfacing faces. The...
A Preliminary study on construction of a high capacity tensiometer and its use in measurement of matrik suction in unsaturated soils Köksalan, Ali Okan; Toker, Nabi Kartal; Department of Civil Engineering (2013) Soil suction is one of the main state parameters that governs unsaturated soil behaviour. Tensiometers are the only type of probe that can measure soil suction directly, but only up to 90 kPa. In the past two decades, a new type of tensiometer with much greater measurement range (up to 2 MPa) has appeared in the literature. The measurement range (i.e. capacity) of a tensiometer is limited by (i) how well it is saturated, and (ii) the air entry value of its porous interface. In this study, the first high cap...
Active microwave remote sensing of soil moisture : a case study in Kurukavak Basin Yılmaz, Musa; Şorman, Ali Ünal; Department of Civil Engineering (2009) Soil moisture condition of a watershed plays a significant role in separation of rainfall into infiltration and surface runoff, and hence is a key parameter for the majority of physical hydrological models. Due to the large difference in dielectric constants of dry soil and water, microwave remote sensing and particularly the commonly available synthetic aperture radar is a potential tool for such studies. The main aim of this study is to produce the distributed soil moisture maps of a catchment from active...
3D modeling of salt related structures in the friesland platform the Netherlands Yücel, Kıvanç; Kaymakcı, Nuretdin; Özacar, Atilla Arda; Department of Geological Engineering (2010) Southern North Sea Basin is one of the mature hydrocarbon basins in NW Europe and is shaped by a number of phases of tectonic deformations during the Phanerozoic. In addition, mobilization and halokinesis of thick Permian Zechstein Salt has enhanced and contributed to the deformation of the region since Triassic, which further complicated the geology of the region. The Friesland Platform, which is a stable platform area located in northern Netherlands, experienced the main deformation phases that Europe has...
