چکیده
Prediction of annual average precipitation over a regin is one of important issues in watersherd management and natural resources planning. Geostatistics is one of the useful methods for precipitation prediction which varies based on type of the variable. This study was conducted in Karoon and Dez Basins located in southwertern of Iran. The data set including 20 years of annual precipitation of stations were used. At first normality and homogeneity of data are examined. Then variographic analysis using three techniques including kriging, co-krigining and Weighted Moving Average (WMA) were applied for predicting annual precipitation. Finally compaction of the results using statistical techniques showed that kinging method has the highest accuracy and provides more accentuate results
