Abstract It is aimed to determine the water quality and pollution parameters which are carried by Gumuscay and Curuksu Creek's to River Buyuk Menderes (RBM). Cause and effect relations of measured parameters are investigated by SPSS 15.00 statistical software \"Factor Analyze\" approach. Temperature, pH, conductivity, salinity, total dissolved solid material, dissolved oxygen demand, chemical and biological oxygen demand values of water samples which are taken from designated measurement stations, are investigated in the light of Water Pollution and Management Regulation. Water samples taken from 6 different location of RBM, Curuksu and Gumuscay, are measured monthly throughout whole year. It is obtained that Gumuscay and Curuksu is 4th, RBM (about Saraykoy Bridge) is 3th class of water quality according to the organic matter concentration values. Total dissolved solid material vales of water samples shows that Curuksu and RBM (about Saraykoy Bridge) is 2nd class of water quality. According to the results, 16 % salinity ratio of Curuksu is due to Gumuscay and approximately 70 % salinity ratio of RBM is due to waters mix from Curuksu.

Abstract Traditional water quality evaluation methods use discrete form that involve upper and lower limits, and the concentrations values are equally important when the values are near to or far away from the limits. Moreover, each quality parameter might belong to one of the four classes; therefore differences of the classes of the parameters may be vagueness. In this study, an index model is purposed for quality evaluation of water quality classification using fuzzy logic. For that purpose, a data set (12 months, total 180 measurements) about several heavy metals such as Copper (Cu), Zinc (Zn), Manganese (Mn), Lead (Pb), Nickel (Ni), Cadmium (Cd) and Iron (Fe) was collected from 5 monitoring stations in Karasu River. After that, fuzzy logic assessment method was used to quality evaluation for heavy metal pollution in Karasu stream. In conclusion, it was supposed that fuzzy logic evaluation method may also be used as an alternative tool for decision-making in environmental management.","PeriodicalId":11598,"journal":{"name":"Ekoloji","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70620540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Examination of the Level of Bacteriological Pollution in the Discharge Area of the Ayamama Stream to the Marmara Sea Abstract In this study seawater samples were taken from Ayamama stream's discharge point and from around of its six different areas every 15 days, and were examined in terms of bacteria such as faecal coliform, total coliform, faecal streptococci, Salmonella spp. and total mezophilic aerobic heterotrophic bacteria from May 2007 to April 2008.

It is found that the area in the best condition is station 6 which is far away 1 km from discharge point and the worst one is station 1 which is discharge point of the Ayamama stream to Marmara sea. Also, it is determined that the number of indicator bacteria show difference depending on months and seasons.
