Determining Boundaries of Morphogenetic and Morphodynamic Regions in the Last and Present Glacial Stage of Wurm in Kermanshah Province

Kermanshah province has various morphogenic regions due to its special topographic and climatic features. The aim of this article was determining and identifying the morphodynamic and morphogenetic regions of Wurm glacial stage and the present status of Kermanshah province using Peltier model. The correlation coefficient and regression line equation of temperature and precipitation with elevation were calculated in the region and then the temperature and precipitation of Wurm last and present glacial stage were obtained using data analysis in SPSS, Excel and ArcGIS. The results showed that the elevation factor is the main controlling parameter of the intensity of the weathering process in the region by changing temperature and annual precipitation parameters. Studying morphogenesis and morphoclimatic areas in two periods indicates that the ocean area has been eliminated at the present time and there was no dried area in Wurm period and also the changes in the boundaries of different areas have not been the same. The highest and the lowest changes have happened in Sawn with 1200 meters and in semi-arid with 384 meters. Glacial regions boundaries were 800 meters lower than present. In a comparison between Wurm stage and present, the most decrease and increase extent of morphogenic regions have happened respectively in glacial areas with 127 times decrease and semi-arid area with 53 times increase.
