High water application uniformity is essential for an effective irrigation. Clogging of emitters in drip irrigation systems is one of the most important factors decreasing uniformity. In this study, the possible effect of magnetization of water on chemical clogging of dripline emitters was investigated. Separate experiments were conducted with three different saline waters (W-1: 0.314 dS m(-1), W-2: 0.665 dS m(-1), W-3: 0.937 dS m(-1)) having a high pH and a positive Langelier saturation index (LSI). Discharge rates, electrical conductivity (EC) and pH's of discharge water from emitters in driplines were measured. Uniformity of driplines was evaluated by using the statistical uniformity coefficient (U-c) and the emission uniformity coefficient (E-u). The pH and EC values of discharge water from emitters in driplines were found to be slightly lower when operated with magnetized water. However, discharge rates under non-magnetized water were lower than those of magnetized water. Magnetic effect was observed to be decreased as the water salinity increased. The U-c and the E-u values indicated that when the medium saline water was magnetized before its release into the system, a better uniformity due to a lower emitter clogging rate can be achieved. When higher saline water was magnetized, lower U-c and the E-u values were observed.

Assessment and prediction of water quality parameters in Lake Köyceğiz using artificial neural network approach Özçelik, Oya; Alp, Emre; Aksoy, Ayşegül; Department of Environmental Engineering (2015) Water quality monitoring plays a significant role on water resources management and planning. European Union (EU) Water Framework Directive aims to achieve “good status” for all waters.. Within the adaptation period to EU, Turkey aims to improve its water quality monitoring network; however, this will lead to time, budget and human resources problems. Purpose of this thesis is the application of a method that will provide water quality assessment (WQA) under limited budget and data conditions. The method wa...
Using cosmic-ray neutron probes in validating satellite soil moisture products and land surface models Duygu, Mustafa Berk; Akyürek, Sevda Zuhal (MDPI AG, 2019-01-01) Soil moisture content is one of the most important parameters of hydrological studies. Cosmic-ray neutron sensing is a promising proximal soil moisture sensing technique at intermediate scale and high temporal resolution. In this study, we validate satellite soil moisture products for the period of March 2015 and December 2018 by using several existing Cosmic Ray Neutron Probe (CRNP) stations of the COSMOS database and a CRNP station that was installed in the south part of Turkey in October 2016. Soil moist...
Investigating the applicability of water sensitive urban design techniques for Güzelyurt, Northern Cyprus Elham, Jahani; Akıntuğ, Bertuğ; Sustainable Environment and Energy Systems (2017-2) Water Sensitive Urban Design (WSUD) is a method used to mitigate the negative effect of urbanization on the water cycle. Due to a high percentage of impervious surfaces in urban area and reduction in the share of infiltration and evaporation, a considerable amount of rainfall is converted to runoff. This increase in runoff portion in urban areas causes serious problems for public and private properties. Moreover, the impact of climate change on more intensive rainfall events would cause serious problems tha...
Use of cadA-Specific Primers and DNA Probes as Tools to Select Cadmium Biosorbents with Potential in Remediation Strategies İçgen, Bülent (Springer Science and Business Media LLC, 2016-05-01) Biosorption, using cadmium-resistant bacterial isolates, is often regarded as a relatively inexpensive and efficient way of cleaning up wastes, sediments, or soils polluted with cadmium. Therefore, many efforts have been devoted to the isolation of cadmium-resistant isolates for the efficient management of cadmium remediation processes. However, isolation, identification and in situ screening of efficient cadmium-resistant isolates are primary challenges. To overcome these challanges, in this study, cadA, c...
Modeling natural attenuation of petroleum hydrocarbons (btex) in heterogeneous aquifers Uçankuş, Tuğba; Ünlü, Kahraman; Department of Environmental Engineering (2005) Natural Attenuation can be an effective cleanup option for remediation of Groundwater contamination by BTEX. One of the important aspects of the methodology that has been recognized recently is that mass removal rates, the most important parameters used to determine effectiveness of the methodology, is controlled by groundwater flow regime, which to a large extent controlled by aquifer heterogeneity. Considering this recognition, the primary objective of this research is to quantitatively describe the relat...
