Abstract

Increasing population growth and the need of this population for agricultural products and water restriction for agricultural products has put the problem of water scarcity very seriously in our country. . Statistics show that per capita water from 4000 to 5000 cubic meters in 1330s has reached to about 1431 cubic meters in the current situation and by continuation of current trends, it would be less than 1, 000 cubic meters in 1400. While the population of the province from 1231204 in 1335 had a population growth to 4879312 in 1390. Research data were twelve elements of water quality including salinity, pH, sodium bicarbonate, dissolved solids, calcium, magnesium, potassium, sodium absorption ratio, chloride, nitrate and sulfate. Cations and anions were taken based on a survey of seven hydrometric stations on Zayandeh Rood river in Esfahan regional-water authority. The periods of data are 1385 and 1390 to 1394. Fuzzy classification analysis was used to determine the extent of water pollution in Zayandeh Rood river by forming a matrix in the row and column dimensions of 760 * 17 in MATLAB software, fuzzy clustering was performed by of fuzzy relations. Finally, the classified maps of authorized to unauthorized limit in the river were drawn by GIS software. The results of classified plots from Choom Bridge to Talab-Gavkhooni show that the amount of all elements in water except chloride and sulfate are high for drinking water, and even in some stations near shoal river, these elements are high and unauthorized for agricultural and industrial purposes
