Introduction: Soil characteristics and water infiltration rate play a crucial role in controlling runoff and flood intensification. The reduction of soil permeability for various reasons such as: land use change, overgrazing, road construction, movement of heavy machinery, etc., will lead to increased runoff and intensification of floods in agricultural lands as well as heavy damage to villagers and farmers. Therefore, preventing these damages requires sustainable management of agricultural lands and attention to the resilience of settlements in rural areas.
Objectives: The main purpose of this study is to investigate the effective parameters on soil permeability and the factors affecting runoff and flood intensification in agricultural lands and settlements in rural areas. For this purpose, it is necessary to study and analyze the amount of water penetration in the soil, obtaining accurate and reliable information.
Methodology: The present study is an applied research using a "descriptive-analytical" method. Geographic Information Systems (GIS) and Hotspot analysis method were applied, which is one of the most important and common methods of studies in the field of geography and soil science.
Geographical Contex: In this study, 88 points of agricultural lands of Khodaafarin County, Gheez Qaleh Si to Ceylon Chay region have been selected as samples.
Result and Discussion: According to the research results, among the studied parameters, two parameters including the percentage of organic matter and soil porosity had a great effect on increasing the rate of water infiltration in the soil and other measured parameters lacked a statistically clear spatial correlation pattern. This indicates the fact that light soils is rich for organic materials as well as soils with porosity (empty space between soils), have high permeability and absorb more water than other soils.
Conclusion: Soil permeatability plays a crucial role in preventing runoff on land, intensifying floods and the reduation of damage in agricultural lands in rural areas. Also, it will contribute to the sustainable development of agriculture as well as the sustainable comprehensive development of rural areas.
