Spatial Analysis of probable maximum precipitation in Iran

Probable maximum precipitation (PMP) is a conceptual structure as the most intense rainfallto dam design, reservoirs and urban projects for our sets. The main goal of this study isdetermine the most probable precipitation and spatial analysis in Iran. Purpose of the 180synoptic stations in Iran, 94 stations have long-term statistics of rainfall (20-55 years) will beselected. Then, using statistical software such as excel and SPSS the amount was calculated.the method used for PMP is Hrshfyld. Finally, using GIS and KRGING we did spatialanalysis. Maps obtained from the maximum probable precipitation in the Iran indicates thatthe spatial distribution of annual precipitation in Iran is uneven. According to existing mapsProbable maximum precipitation related to the northern and southern Iran.thus PMP from the south coast of Iran to central of Iran decrease and from the central area tothe north coast increase.
