The purpose of this study was to determine the changes in concentrations of phosphorus and iron in pondwater and porewater in the littoral zone of Sakaryabasi-Kirkgiz pond in central Turkey. The pond supplies water to the Rainbow Trout Fish Culture and Research Station in four months in which temperatures do not show a strong variation (16degreesC-22degreesC). Concentrations of soluble reactive phosphorus were 4- to 5-fold higher in porewater than in pondwater; thus, diffusion of SRP from porewater to pondwater might be possible. Water content of the sediment was high, although loss on ignition ranged from 13 to 18% and iron content ranged from 0.16 to 0.22 mg/gdw. The total phosphorus content of the sediment was high, with a range 0.64 to 1.70 mg/gdw, and organic phosphorus was the dominant sedimentary phosphate pool in October, January, and April. Despite having calcerous sediment in the drainage area, a relatively low quantity of phosphorus was bound to calcium and aluminium. In April and October, sediment phosphorus and SRP in porewater and overlying water were greater than in other months. Our results suggest that it would be more appropriate to control phosphorus concentration in spring and autumn than in the warm summer months.


Composition of atmosphere at the Central Anatolia
Yörük, Ebru; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2004)
Concentrations of elements and ions measured in samples collected between February 1993 and December 2000 at a rural site in central Anatolia were investigated to evaluate the chemical composition of atmosphere at central Anatolia, to determine pollution level of the region, to study temporal variability of the pollutants and to investigate the sources and source regions of air pollutants in the region. Level of pollution at central Anatolia was found to be lower than the pollution level at other European c...
Assessment of management policies for lake Ulubat basin using avswat
Bulut, Elif; Aksoy, Ayşegül; Department of Environmental Engineering (2005)
This thesis assesses phosphorus loads and management practices to control nutrient transport to Lake Uluabat. It analyzes nonpoint sources of pollution, especially agricultural pollution, throughout Uluabat Basin (watershed). AVSWAT (ArcviewTM Interface of Soil and Water Assessment Tool 2000) was used in determination of phosphorus and sediment loads to Lake Uluabat. Contribution of soluble phosphorus (SOLP) loads from agricultural sites was discussed. Seven scenarios were applied through watershed area to ...
Levels and sources of polychlorinated biphenyls in Ankara creek sediments, Turkey
Ozyurek, Nazan Akduman; Gedik, Kadir; Sıltu, Esra; İmamoğlu, İpek (Informa UK Limited, 2013-06-01)
The spatial distribution, degree of pollution and major sources of polychlorinated biphenyls (PCBs) were evaluated in surficial sediments of Ankara Creek, located in the capital of Turkey and serving as one of the tributaries in the third largest watershed in Turkey. Sediment sigma PCB concentrations analyzed on Aroclor and congener basis (seven indicator congeners) range from 5.5 to 777.6ng g1 and 3.7 to 743.3ng g1 dw as Aroclor and congener based concentrations, respectively. High concentrations of sigma ...
Soil erosion risk mapping using geographic information systems : a case study on Kocadere creek watershed, İzmir
Okalp, Kıvanç; Akyürek, Sevda Zuhal; Department of Geodetic and Geographical Information Technologies (2005)
Soil erosion is a major global environmental problem that is increasing year by year in Turkey. Preventing soil erosion requires political, economic and technical actions; before these actions we must learn properties and behaviors of our soil resources. The aims of this study are to estimate annual soil loss rates of a watershed with integrated models within GIS framework and to map the soil erosion risk for a complex terrain. In this study, annual soil loss rates are estimated using the Universal Soil Los...

The organic carbon contents and textural composition of a total of 166 surficial sediment samples (from 10 to 1226 m water depths) together with data on primary productivity rates and dissolved oxygen concentrations have been studied to investigate the main controls on the distribution of organic carbon buried within the modern sediments across the Sea of Marmara.
