In this study, trends in selected water quality parameters in Eymir Lake over a period of 10 years are analyzed using the Mann-Kendall test. Analyzed water quality parameters are dissolved oxygen (DO), total phosphorus (TP), total suspended solids (TSS), and secchi depth (SD). In addition, trends in the yearly averages of precipitation, lake volume, and ambient temperature are examined. According to Mann-Kendall test results, precipitation, volume and ambient temperature values exhibit decreasing trends in 1998-2008. DO and TSS exhibit increasing trends while TP and SD have decreasing trends in Eymir lake. The change in the volume of the lake has a significant impact on the trends of DO, TSS, and SD. These results indicate that, besides eutrophic conditions, water balance and drought conditions significantly impact the water quality of Eymir Lake.

Trend Analyses of Meteorological Variables and Lake Levels for Two Shallow Lakes in Central Turkey
YAĞBASAN, ÖZLEM; Demir, Vandettin; Yazıcıgil, Hasan (2020-02-01)
Trend analyses of meteorological variables play an important role in assessing the long-term changes in water levels for sustainable management of shallow lakes that are extremely vulnerable to climatic variations. Lake Mogan and Lake Eymir are shallow lakes offering aesthetic, recreational, and ecological resources. Trend analyses of monthly water levels and meteorological variables affecting lake levels were done by the Mann-Kendall (MK), Modified Mann-Kendall (MMK), Sen Trend (ST), and Linear trend (LT) ...
Spatial data analysis for monitoring and prediction of selected water quality parameters in reservoirs: Porsuk Dam reservoir case
Yenilmez, Firdes; Aksoy, Ayşegül; Düzgün, H. Şebnem; Department of Environmental Engineering (2014)
In the design of a water quality monitoring network, selection of water quality sampling locations is crucial to adequately represent the water quality of the water body when high costs of analyses and field work are taken into account. In this study, a new approach was proposed to identify the representative water quality sampling locations in reservoirs and lakes using geostatistical tools for estimation of spatial distribution of selected water quality parameters. To do so, kernel density estimation (KDE...
Fluid migration and rheological properties of different origin G-class cements in oil well drilling applications
Kök, Mustafa Verşan (2018-01-01)
In the first part of this study the effect of free water on fluid migration potential is tested for different cement slurries using standard API G-class quality tests. Static gel strength analyser is also used to measure the static gel strength of cement slurries. Three different class G type cement samples were tested according to their free fluid values which are 2.5%, 5%, 3.12% respectively, and it is found that A-type cement, with lowest free fluid content, has the lowest potential for fluid migration. ...
Water recycling and reuse in soft drink/beverage industry: A case study for sustainable industrial water management in Turkey
Alkaya, Emrah; Demirer, Göksel Niyazi (2015-11-01)
The aim of this study was to investigate water conservation and reuse opportunities in a soft drink/beverage manufacturing company. Water use analysis and benchmarking were carried out to determine the areas and processes where significant water saving potential is present. Based on evaluations, water recycling and reuse practices were realized in cooling systems. As a result of applying these practices, the total specific cooling water demand of the company was reduced from 14.4 to 1.2 m(3)/m(3) product or...
Impacts of climatic variables on water-level variations in two shallow Eastern Mediterranean lakes
Yagbasan, Ozlem; Yazıcıgil, Hasan; Demir, Vahdettin (2017-08-01)
Variations in temperature and precipitation have direct impacts on the physical, chemical and biological characteristics of the shallow lakes. This paper examines the possible linkages between climate variables and the water levels of shallow interconnected Lakes Mogan and Eymir, located 20 km south of Ankara in Central Anatolia. The variations in the lakes' water levels during 1996-2015 are studied and the impacts of climate variables on the lake levels are assessed to address the long-term consequences. T...
