Abstract

In this research, the goal of evaluating the accuracy of interpolation methods is the prediction of spatial distribution of some of the quality indices of groundwater in Urmia plain. At first, the water quality data of 20 wells in the years of 2001-2014 were analyzed. The Kolmogorov-Smirnov test showed that the data were not normal and therefore the conversion of the box-cox was used to normalize them. Then, using the GIS software, the best semivariogram model was fitted to the spatial structure of the data. The results showed that for water quality parameters, circular, spherical, and exponential models are the best models for semivariogram. Then, the spatial variations of parameters were studies using different interpolation methods such as KRIGING and Inverse Distance Weight with power of one to three. Then, the ZONING maps of qualitative parameters were drawing with the most appropriate method in the ArcGIS software. Plain aquifer was also examined considering WILCOX and SCHOELLER standards for agricultural and drinking purposes. The results of the Wilecox and SCHOELLER standard showed that 40% of the wells in the plain have brine water to use for agriculture. Also the wells above are of good quality and acceptable for drinking.
