Nilufer River is the main receiving body of water for the industrial and domestic wastes of 1.000.000 populated Bursa metropolitan area and it combines with Kocasu River before entering the sea at the south Marmara region, Turkey. Variations in concentrations of Na, K, Ca, Mg, Fe, Cl, SO4, PO4, NH4, NO3, NO2, BOD5, COD, polyaromatic petroleum hydrocarbons (PAH), pH and some heavy metals (Hg, Cd, Cr, Zn, Pb) were seasonally determined in 1991-94 period. The results showed that these rivers are included in the heavily polluted class of waters.


Evaluation of the alternatives to improve water quality in Gürdük watershed using swat model.
Kabal, Cevdet; Alp, Emre; Department of Environmental Engineering (2019)
Gürdük Watershed is a part of Gediz Watershed and it is located is in Aegean Region. The Watershed covers an area of approximately 3,200 km2. Within the boundaries of Gürdük Watershed, there are 10 districts of Manisa. Since Gürdük Watershed has fertile soil and a suitable climate for agriculture, the region is at the forefront of agricultural production in Turkey. More than 50 % of the watershed consists of areas with agricultural lands. Within of the scope of this thesis, the current pollution status of t...
Evaluation of eutrophication control strategies for the Keban Dam reservoir
Soyupak, S; Mukhallalati, L; Yemisen, D; Bayar, A; Yurteri, C (1997-04-15)
The reservoir of the Keban Dam in eastern Anatolia is a very deep and large water body subject to significant seasonal water level fluctuations within a given hydrological year. At the present time, different sections of the reservoir have different trophic status and the upper portion of the reservoir, in particular, is eutrophic. In this regard, there is a need for the assessment of alternative strategies to be implemented for phosphorus and thus eutrophication control in this segment of the reservoir. In...
Estimation of diffuse pollution loads of pesticides in tersakan sub-basin of Yeşilirmak river
Ayyıldız, Ceren; Ünlü, Kahraman; Department of Environmental Engineering (2019)
Tersakan Creek is one of the highly polluted tributaries of Yeşilırmak River because it receives pollution loads both from discharges of the industrial facilities and run-off water of the agricultural areas in the sub-basin. A monitoring program was implemented to determine the water quality status of the sub-basin in accordance with the EU Water Framework Directive (WFD). The results of the water sample analyses revealed that concentrations of 22 pesticides, out of the detected 57 pesticides, exceeded the ...
Monitoring of Aquatic Environments with Innovative Sampling Techonologies - Semipermeable Membrane Devices (SPMD):A Case Study at Yeşilırmak Basin
İkizoğlu, Z Rana; Avaz, Gülsen; Canlı, Oltan; Olgun, Elmas Ö; Yetiş, Ülkü (null; 2018-12-06)
Yeşilırmak River Basin ranks 3rd in the 25 river basins in terms of surface area across the country. In this huge land area, agricultural, industrial and animal feeding activities are the most significant sectors for the socio-economic progress especially in the last few decades. Due to the rapid increase in this activities and legal requirements arised from Water Framework Directive (WFD) , water quality deterioration risk sourced from micropollutants has been gradually gaining more significance. In line w...

The Bafra alluvial plain, where the Kızılırmak River discharges into the Black Sea, is one of the most critical examples of severe coastal erosion problems in Turkey. The amount of sediment carried by the Kızılırmak River has decreased from approximately 23 million ton per year to 0.46 million tons/year starting from 1960s as a result of construction of flow regulatory structures in the following years. This drastic decrease in the amount of sediment carried by the river resulted in a severe shoreline retre...
