Objective: Rural settlements, as one of the major forms of human settlement, are directly influenced by geological, geomorphological, hydrological, and tectonic conditions in many mountainous regions of the country. The location of settlements on steep slopes, landslide-prone areas, and in proximity to active faults can increase their vulnerability to natural hazards and impose significant constraints on physical development and population safety. This study aims to investigate the location of the physical fabric of Chezi Olya Village in Andika County and identify the geomorphological hazards affecting the safety and future development of the settlement.
Method: This study employed a descriptive–analytical approach. Data were collected and examined through documentary studies, assessment of environmental characteristics, and field observations and surveys of the geological and geomorphological conditions and existing hazards within the village area.
Results: The results showed that the physical fabric of Chezi Olya Village is located in a mountainous area and has developed on materials and deposits associated with an ancient landslide. Steep slopes, cliffs and rock walls, deep and narrow valleys, an active landslide, and rockfall are among the major natural hazards and constraints in the area. In addition, the village's proximity to the active Andika Fault and its location on landslide deposits exacerbate unfavorable geotechnical conditions and limit the potential for safe physical development. Field investigations also showed that, in some parts of the village, the presence of detached rock blocks and unstable slope conditions poses a potential threat to settlement and human activities.
Conclusions: Accordingly, continued physical development of the village without considering geomorphological and geological constraints may increase its vulnerability to landslides and earthquakes. Therefore, securing the settlement, preparing maps of areas suitable and unsuitable for construction, managing surface water, avoiding development in unstable areas, and incorporating the findings of natural-hazard assessments into the village guiding plan are essential. Adopting this approach can reduce the risks associated with landslides and other natural hazards while providing a basis for directing the future development of the village toward safer areas. |
