“…Bu sucul bitkiler öldüğünde organik maddeler taban suyuna çöker ve mikroorganizmalar (bakteri gibi) tarafından -proseste oksijen tüketerek-hipoksiya ya da ekstrem durumlarda anoksiyaya neden olabilirler [6]. Göl ötrofikasyonu, uzun yıllardır Dünya çapında sucul ekosistemlerin sağlığına bir tehdit olarak kabul edilmiştir [8][9][10]. Besin maddeleri sucul ortamların içine iki modda (statik ve dinamik olarak) salınırlar.…”

ÖZÖtrofikasyon göl, haliç, rezervuar, kıyı alanları, yavaş hareket eden akarsular ya da Baltık Denizi gibi aşırı besin maddesi alan denizlerin yapısındaki su kütlelerinde meydana gelen ve plankterlerin aşırı büyümesi/artışını tetikleyen bir süreçtir. Ötrofikasyon kıyı alanlarda tür dağılımını ve ekosistem fonksiyonunu etkileyen bir çevre sorunudur ve özellikle iki ana besin maddesi (azot ve fosfor) bu süreci harekete geçirir. Ötrofikasyon etkilerini mikroskobik fitoplankterler, filamentli algler ve sucul bitkilerin çoğalması sonucu su ortamında berraklık azalması ile yansıtır. Ötrofikasyonun ileri aşamaları mavi-yeşil algleri (siyanobakteriler) içeren alg patlamaları ve balık stoklarında dramatik değişikliklerle sonuçlanır. Günümüzde ötrofikasyon durumu değerlendirilmeleri, ötrofikasyon izleme verilerine dayanır. Bu çalışmada, Dünya ve Türkiye'deki ötrofikasyon durumu ve senaryoları iklim değişikliği, kirleticiler, besin maddesi artışları gibi faktörler göz önünde tutularak genel çerçevede incelenmiştir.Anahtar Kelimeler: Besi maddesi, çevre, ötrofikasyon, sucul ortam, su kirliliği EUTROPHICATION STATUS AND SCENARIOS IN AQUATIC ENVIRONMENTS ABSTRACTEutrophication is a process that occurs in the water columns such as lakes, estuaries, reservoirs, coastal areas, slow-moving rivers or the Baltic Sea that receive excess nutrients, triggering the overgrowth of plankton. Eutrophication is an environmental issue that affects species distribution and ecosystem function in coastal areas, and in particular the two main nutrients (nitrogen and phosphorus) are involved in this process. The effects of eutrophication are reflected by microscopic phytoplankton, filamentous algae and aquatic plants with a decrease in clarity in the water. Further stages of eutrophication result in algal bloom containing blue-green algae (cyanobacteria) and dramatic changes in fish stocks. Today, assessment of eutrophication status is based on eutrophication monitoring data. In this study, eutrophication situation and scenarios in the World and Turkey have been assessed in the general framework considering factors such as climate change, pollutants and nutrient increase.

The characteristics of water in the Turawa reservoir, one of the important storage reservoirs in Poland, were thoroughly studied. The reservoir and also the rivers flowing into the reservoir were monitored in the period 2004-2006 with respect to the basic physico-chemical parameters determining the quality of water such as water temperature, specific conductance, pH, biochemical oxygen demand (BOD 5 ) and chemical oxygen demand (COD Mn ), water hardness, content of typical ions (sodium, potassium, sulphates, phosphates and chlorides), heavy metals, and so on. The observed seasonal and long-term changes of the parameters measured were discussed and the processes responsible for the changes suggested. The causes of the observed deterioration of the ecological status of the Turawa reservoir were given and the remedial operations proposed. The latter included improvement in the management of solid wastes and wastewater in the area, reducing the runoff of nutrients in the catchment, decrease in discharge of pollutants into the rivers flowing into the reservoir, removal of bottom sediments and also increasing the average water table and decreasing its fluctuations. The effect of the remedial operations will be further studied.

“…The lake located at 1887.4 m above sea level, has a surface area of more than 300 km 2 and an average depth of only 4.4 m (Tanaka et al 2013). Since the 1980s, following rapid economic growth and urban expansion of Kunming, the external nutrients inputs have been larger than the tolerance limitation of Lake Dianchi, which has resulted in the problems of water quality deterioration and severe eutrophication (Liu et al 2014). Thus, it is necessary to mitigate the external nutrients inputs.…”

“…Due to the complexities of multi-period mitigation guidelines, the mitigation rates may vary with the preference of local authorities, which would lead to various possibilities in nutrient load emission permits. For better reflecting the flexibility of the decisions, TN and TP emission permits can be treated as fuzzy sets (He et al 2008 (Gao et al 2014;Liu et al 2014). Accordingly, we set the TN emission permit for urban drainage as (7720, 7810, 7900), (6940,7030,7110), and (6250, 6325, 6400) tonnes/year during periods 1, 2, and 3, respectively.…”

In this study, interval mathematical programming (IMP), m λ -measure, and fuzzy chance-constrained programming are incorporated into a general optimization framework, leading to a generalized interval fuzzy chance-constrained programming (GIFCP) method. GIFCP can be used to address not only interval uncertainties in the objective function, variables and left-hand side parameters but also fuzzy uncertainties on the right-hand side. Also, it can reflect the aspiration preference of optimistic and pessimistic decision makers due to the integration of m λ -measure. The developed method is applied to the long-term planning of a domestic wastewater management system in the city of Kunming, China, with consideration of the eco-environmental protection of downstream water body. The solution results of the GIFCP method can generate a series of optimal wastewater allocation patterns and WTPs capacity expansion schemes under different risk levels, provide in-depth insights into the Water Resour Manage (2015) 29:3015-3036 effects of uncertainties, and consider the proper balance between system cost and risk of constraint violation.
