WATER QUALITY TENDENCY OF AKARÇAY RIVER BETWEEN 2006-2011

In this study, water quality trends from 2006-2011 of akarcay river were analyzed. in river, physical and inorganic chemical parameters defined in water quality control regulation have been measured by state hydraulic works since 1991. measured physical and inorganic chemical parameters in araplı river, afyon sewage output, sugar factory output and bolvadin bridge of river were used. statistical properties of data and to understand the variation in time, parameters –time correlation and regression analysis and also parameter-discharge correlations were calculated. according to these analyses results, current pollution status for last five years, variation of quality parameters and interaction among them were determined. moreover, analysis results were interpreted to define the effect of pollution sources on quality variation.
