Two natural lakes named Eymir and Mogan are experiencing with eutrophication problem. Rehabilitation alternatives for the lake system have been studied in detail; suitable management and pollution prevention plans were established using an integrated system analysis and modelling approach. The effectiveness of different management scenarios have been evaluated.


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...
Similarity between contemporary vegetation and plant remains in the surface sediment in Mediterranean lakes
Levi, Eti E.; Cakiroglu, Ayse I.; Bucak, Tuba; Odgaard, Bent V.; Davidson, Thomas A.; Jeppesen, Erik; Beklioğlu, Meryem (2014-04-01)
Aquatic macrophytes are commonly used to assess the ecological condition of lakes. Little is known, however, about long-term macrophyte dynamics in shallow lakes. In the absence of historical data, the remains of macrophytes (fruits, seeds and vegetative fragments) found in lake sediments may provide just such information. In order to interpret confidently past change in aquatic plant communities from their sedimentary remains, it is vital to establish the similarity between the contemporary and fossil asse...
Role of hydrology, nutrients and fish predation in determining the ecology of a system of shallow lakes
Özen, Arda; Beklioğlu, Meryem; Department of Biology (2006)
In this study, the hydrology and physical, chemical and biological variables of a shallow lake system including the Lakes Mogan and Eymir between 1997-2005 were evaluated. In Lake Eymir, a biomanipulation study was conducted between August, 1998 December, 1999. Upon biomanipulation, Lake Eymir shifted to clearwater state with submerged vegetation domination during 2000-2003. However, in 2004, the lake shifted back to algae-dominated turbid state since the buffer mechanisms provided by submerged plants were...
Optimal management of a coastal aquifer in southern Turkey
HALLAJI, Khosrow; Yazıcıgil, Hasan (1996-01-01)
Seven ground-water management models were developed to determine the optimal planning and operating policies of a costal aquifer in southern Turkey threatened by saltwater intrusion. Steady-state and transient finite-element simulation models, representing the response of the system, are linked to linear and quadratic optimization models using response functions. Optimal pumpage policies were determined for 94 wells under three management objectives that maximized agricultural water withdrawals and minimize...
Use of waste pyrite as an alternative to gypsum for alkaline soil amelioration
TOZSİN, Gülşen; Arol, Ali İhsan; ÇAYCI, GÖKHAN (Informa UK Limited, 2015-05-04)
The reclamation of alkaline soils is of great interest especially in arid and semi-arid climatic regions of the world. The aim of this study was to investigate the application of pyrite from the waste materials of a copper concentration plant as an alternative to gypsum application for alkaline soil amelioration. The second aim was to assess heavy metal contamination. Waste pyrite (FeS2) obtained from a copper concentration plant and pure gypsum (CaSO4 center dot 2H(2)O) were added to soil within the column...
