Physical and chemical characteristics of lake w a t e r s a n d t h e i r v a r i a t i o n s g o v e r n t h e environmental, ecological, and biological status of the lakes. Lakes are also subjected to a high human impact. Many studies examined the physical and chemical status of the lake water and demonstrated which factors controlled the water quality, ecologic status and eutrophication patterns [1-6]. Lake Uluabat is one of the most important wetland area in Turkey and is increasingly threatened by pollution [1]. Organic and inorganic pollution has also affected the nutrient status of the lake, and in this respect, the greatest concern deals with eutrophication [7-8]. Intensive agricultural activities, industrial activities, and mining in the lake basin have adversely influenced the water quality in the lake. Water quality of the lake is somewhere limited. It is therefore essential to prevent and control water pollution and to implement regular monitoring programs for water quality management [9]. Lake Uluabat is one of the richest lakes in terms of aquatic plants besides fish and bird populations in Turkey. For this reason, the Lake was placed under protection by the RAMSAR agreement in 1998 and the living lakes partnership program of 2002. The aim of this study was to examine water quality variables in Lake Uluabat each month between August 2013 and July 2014, to classify the lake water quality according to the "SWQMR". Also, eutrophic level of the lake has also been identified. This study will provide baseline data for future water quality and management studies.

“…Water quality model combined with hydrodynamic model has made great progress not only for two dimensional analysis in the past few decades but also towards adding more complex interactions between physical, chemical and biological processes [7]. Most numerical models of water quality were established for regular monitoring indicators such as BOD, DO and nutrients [8]because of their limited monitoring data [9]and their crucial influence on the water quality [10] and [7]. Several studies showed that water quality models were applied to continuous organic pollutants in which adsorption was considered to be an important process.…”

“…This modeling suite was developed by Deltares can perform a simulation of both hydrodynamic and water quality and also solve the coupling situation related to different time and spatial scales used in both compartments. In particular, the mathematical model Delft-FLOW is used for hydro-dynamic simulation [10]and Delft-WAQ for water quality simulation [12]since there are many studies that show this modeling suite has a good performance for hydrodynamic and water quality modeling [13] and [14]. In this study, Delft software model is applied to simulate emerging contaminants in the last reach of Rosetta branch from a thermal source of cooling water from a power plant.…”

The present study was conducted to evaluate the environmental impact of thermal effluent sources on the main water quality parameters at the low flow conditions. The low flow causes the flow velocity to be low which causes accumulation of any pollutant source. The study was performed by creating a 2-d model of the last reach of Rosetta branch at winter closure. Delft 3d software is used to create a hydro-dynamic model to simulate the flow pattern within a 5 km of the branch upstream Edfina regulator. Water quality model is coupled afterwards to simulate the water quality parameters. A base case scenario of the current state at the low flow condition is set up and calibrated. Another scenario is performed after adding a thermal pollutant source. Thermal power plant is used as an application of thermal pollutant source. Cooling water is with drawled from an intake and discharged back to the water source with a relatively higher temperature downstream the intake. A case study of Dairut thermal power plant which is planned to be constructed at this area is used. Hydrographic survey is performed to collect essential hydraulic data for the model. Field measurements are performed to collect water quality along the area. A numerical model was set up and the area was simulated. Results showed accumulation of thermal plume. The higher temperatures lowered the dissolved oxygen in the thermal plume area. On the other hand, BOD and NO3 values increased with different rates. Ammonium was positively affected and was lowered.
