In urban geomorphology, the important factor of urban areas’ development is considered to be the artificial change and transformation of the ground’s crust and the effect of human activities on the crust, as well as natural factors. Consequently, the daily growth of cities caused by the population growth and migration has led to unplanned constructions and vast changes in the spatial structure, specially the physical development of city in unfavorable natural locations, which calls for conscious guide and major organization.
Unbridled and inconsistent development of urban areas due to human activities with the aim of urban development, directly changes vast areas of ground crust in a very short period of time, which is apart from the long- geomorphologic effect and its natural process. These facts lead to the appearance of dangers that are, according to experience, sometimes hard to predict and accompanied by life and property losses. Accordingly, in this paper the deficiencies and natural dangers in the city of Hashtrud are displayed through geomorphologic examination.
