Today, most researchers use remote sensing techniques to study natural hazards and identify periodic changes, and the use of these techniques has always been a useful tool for researchers due to its accuracy and ease of use. Meanwhile, the study of floods as a natural hazard is often considered as a blue zone in satellite images with the help of various indicators. This study zoned the flood-affected rural areas in Hoveyzeh city using satellite imagery and remote sensing and normalized water difference index (NDWI). Thus, after preparing Landsat 8 satellite images for 2018 and 2019, geometric and radiometric errors were performed on them in Envi 5.3 as a preprocessing of this type of data. Base (2018) was identified and finally with its output in Arc Gis, rural areas affected by floods in Hoveyzeh city were identified. The results showed that out of 137 rural points in this city, 10 villages were seriously damaged in the flood of April 2017. This number of villages includes 19% of the total population of rural areas of Hoveyzeh city, which is 38% of the total population of the studied city, which is considered a high population. Thus, with the identification of affected rural areas in the study city, planning to improve the situation of these areas is necessary for planners.
