Abstract

In this study, appropriate interpolation methods for PRECIPITATION changes are introduced, The performance of the methods was examined by Geostatistical techniques. Geostatistical method are of the most important methods to estimate the SPATIAL DISTRIBUTION of PRECIPITATION. For this purpose, the monthly PRECIPITATION data from 16 meteorological stations and 31 synoptic stations from the East Azerbaijan Regional Water Authority in a joint 20-year period (2005-1986) was prepared. The method of simple KRIGING (SK), ordinary KRIGING (OK), and universal KRIGING (UK) were used to estimate the annual average rainfall in the North West. calculated and plotted for each model, the rooted mean squared error and determination coefficient (r) between the observed and estimated errors of the maps, and a map was selected. The results based on the criteria of RMS and RMSE showed that the geostatistics method KRIGING simple exponential model was selected due to its standard measurement error, and also a correlation coefficient (r) greater than other methods. As the most suitable method for the preparation of the map element it was determined by rainfall in the North West.
