When compared to the 1960s, the number of floods has grown by nearly tenfold in the previous decade. A flash flood occurred in numerous areas of Iran in March 2019, including Golestan Province, particularly Aq Qala County, as a result of heavy and unexpected rain, causing financial and human losses. This study is in applied form, using a descriptive-analytical technique based on field studies. According to the 2016 census, the statistical population of the current study is the homes of six villages in the central area of Aq Qala County, which total 4639 households. Cochran's algorithm was used to choose 270 persons as a sample. The Cronbach-alpha coefficient, which is equivalent to 0/82, was used to determine the dependability of the research components. The findings of the Chi-square correlation study show that each of the investigated parameters has a 99 percent association with flood damage in the communities under investigation. Furthermore, the Friedman test findings demonstrate a significant difference up to a 95% confidence level. According to the Kruskal-Wallis test findings, there is no difference in the amount of damage between villages in terms of natural components, but there is a substantial difference between villages at the level of 95 percent for the component of encroachment on the river and development in its region. The ANOVA test demonstrates that there is a significant difference of 99 percent between the villages in the amount of damage in their distinct portions when the average damage across the six analyzed villages is compared. Different communities were categorized based on this, which explains the extent of damage, using Duncan's post hoc test. The cause of numerous types of damage to settlements is determined by the land's slope, the village's elevation above sea level, and, most importantly, the village's closeness to the Qarah Su and Gorganrud river floods Although the villages of Sahne Sofla, Dugunchi, and Yampi were flooded as a result of significant rainfall in a short period, the villages of Qanqormeh, Yolmeh Khandan, and Chensouli sustained less damage. After all, the lack of river dredging, progressive expansion on river land, and random degradation of riverbeds have all contributed to the severity of flood damage in the communities investigated.
