These crises are increasing because of human activities in urban areas. Therefore, in this study, the constraints and the capabilities of Maragheh have been assessed by identifying of the geomorphological processes and phenomena in the developed parts of Maragheh during the yeas of 1984 to 2017. Geomorphologic constraints in this study have been discussed in two categories of constraints due to hillslope, and flood processes. For this purpose, the needed data were gathered from different sources, as well as distant evaluation. Then, these data were changed into the necessary information layers by using the Geographical Information System (GIS), which included the geological, tectonic, seismicity, temperature, humidity and rainfall, soil erosion, the application of the land and vegetation, height classes, slope, the distance from the water ducts, and soil type information layers. Later, to align the information layers with each other, the layers were standardized by using Fuzzy Logic Theory. To get the relative value of each layer in determining the geomorphological areas, the analytic hierarchy process (AHP) was used. The results obtained from the analytic hierarchy process indicates that in the studied region, the role of the geological structures in the geomorphological events is remarkable. After the relative evaluation of the information layers, the super-positioning of the layers was done by using Simple Additive Weighing (SAW). The findings reveal that the northeastern part of Maragheh has more possibility of hillslope process and flooding point of view than the other parts. In addition, in order to study the hazard extent in the developed parts in the recent decades, firstly, the extent of the physical development of the city during the years of 1984 and 2017was extracted through Landsat Satellite Pictures. Then, after matching with the land application maps, the process of the physical development of the city was studied in the above-mentioned period. The Crosstab Table Method was used for this purpose. The obtained results from the study of the process of the city development in the above-mentioned period showed that the most city development has been occurred in the areas that possess the higher geomorphological hazards and this needs better management of directing the physical development of Maragheh in the less hazardous areas. %U https://jhsci.ut.ac.ir/article_64893_8b856d825d23bad5c13370122892678c.pdf
