The study was conducted for the period between 2000-2013 for the months of February, April, June, August, October and December. The results received were analyzed for temperature, pH, EC, Cl<sup>-</sup>, Na, Ca<sup>2+</sup>, Mg<sup>2+</sup>, K<sup>+</sup>, , TDS, TH and SS aquaculture. The results of the analyses revealed that although the water pollution in the river showed variations throughout the year, in fact the samples obtained at various locations displayed high levels of pollutants. The “Regulation on Turkish Water Pollution Control” was made use of in classifying the parameters of the water in this study. These parameters were compared with the WHO Guidelines and TS-266. Among the 8 Dams that were included in the study, the best quality of water was measured in the Adügüzel Dam, which gave the lowest values;and the levels were measured to be higher in the Saraykoy Station than those of the other dams. There was a severe drought in Menderes Basin in 2007, and therefore the highest annual values were measured for the year 2007. In those years, the levels of the irrigation water decreased as low as 4255 m<sup>3</sup>/ha. The SPSS 21 Statistical Analysis Program was made use of in analyzing the data of the study. The One-Way Anova and Tukey Multiple Comparison tests were also used for the analyses of the data as well. The p < 0.05 level was accepted as being significant in the analyses. The distribution of the data was performed by using the Box-plot Graphs. Furthermore, the effects on fish species and the pollution in Büyük Menderes River were also examined in the study.展开更多

In this study, 16 irrigation schemes (Baklan, Irgilli, Sutlac, Cal, Cürüksu, Nazilli, Saraykoy, Pamukkale, Sultanhisar, Akcay, Aydin, Topcam, Karpuzlu, Isikli, Gümüssu ve Soke) having 166,381 hecta...In this study, 16 irrigation schemes (Baklan, Irgilli, Sutlac, Cal, Cürüksu, Nazilli, Saraykoy, Pamukkale, Sultanhisar, Akcay, Aydin, Topcam, Karpuzlu, Isikli, Gümüssu ve Soke) having 166,381 hectares, built by State Hydraulic Works (DSI), and operated by participatory irrigation managements, and 14 hydroelectric power plants (HPP) operated and built on dams, canals and rivers by the public and private sectors are examined in the Büyük Menderes basin which is an important basin in terms of the agriculture, energy and ecology projects. Integrated basin management practices and the importance and role of irrigation and hydropower plant operation in integrated basin management, how it should be, optimal use of available water resources for irrigation and hydroelectric power plant operation, irrigation relationship with canal hydropower plants, operated under integrated basin management of irrigation and hydropower plants, environment and the ecological effects have been studied, and integrated basin management with the existing basin management conditions in terms of hydropower plant and irrigation operation on the basis of data of 2015 have been compared, reached important conclusions, and made recommendations on the subject.展开更多

INTRODUCTIONMeanders are a common river channel pattern. It is generally accepted that comparatively low sediment concentration, especially when bed material load is considered, is one of the fundamental conditions for the formation of meanders. With an increased sediment concentration, the river channel pattern will be transformed from a meandering one to a braided one. However, in our opinion, this holds true only for rivers whose sediment concentration is within the normal range. In studying alluvial rivers in wide valleys on the展开更多
