Abstrakt: A comprehensive investigation into the geographic or geomorphic phenomena of a region is crucial for various purposes such as managing resources effectively, and applying the acquired knowledge for regional development. The foundational step in such regional assessments lies in understanding the physical characteristics of the areas under consideration. In this context, the identification of morphogenetic region(s) is particularly significant for geoscientists, geotechnical experts, and planners. This study employed the Lewis Peltier models to analyze the Paveh Rood watershed basin, focusing on two key variables: average temperature and annual rainfall. To examine and categorize the weathering and geomorphological areas within the studied region, climatic data--specifically average annual rainfall and temperature--were obtained from five synoptic stations of the General Meteorological Department of Kermanshah. Subsequently, this data was input into GIS software for analysis. The Peltier models were applied to determine regimes for each station, including the assignment of weight values. The outcomes were then recorded in a database, and relevant maps were generated using ArcMap software. The findings revealed that, among the nine morphogenetic conditions outlined in the Peltier model, five are manifested in the climatic conditions of the region. In terms of weathering processes, it was observed that the oceanic, temperate, and Selva regions undergo significant chemical weathering, characterized by a robust washing environment. In contrast, the savannah and semi-arid regions, specifically the northwestern region and the center of the basin, experience moderate and weak weathering, respectively. [ABSTRACT FROM AUTHOR]
