Abstract :
Development and establishment of settlements in direct contact with the natural base and geomorphology effects. Because of the topography and geology of the study area has certain limitations in terms of localization and development of their human settlements. In order to reduce the risks of the South West province of Khorasan Razavi and modify future plans of development and human settlements, to assess the feasibility of the study area was investigated. After studies and library and a selection of appropriate measures, using phase logic models, and GIS software to help, areas prone to develop settlements were determined. In this study was to identify suitable areas for development and the creation of settlements in the study area based on Landform, from eleven parameters, slope, aspect, elevation, soil, land use, elevation, distance to fault, distance from the river, away from the road distance from settlements, geomorphology as independent variables in recognizing the potential and geomorphological constraints in the region were selected. Finally, after zoning based on phase model, the results showed that about 61 percent of the study area is located on the floors very poor and poor, which means unfavorable geomorphological conditions in this part of the study area to develop settlements are human. About 16.40% of the study area has average conditions for the development and creation of new human settlements respectively. And about 23 percent of the area under study geomorphological area of favorable conditions for construction activity and the construction of new residential areas are.
