Abstract
Materials and methods:
In the present review research, articles and reports related to flood and drought phenomena in Kerman Province (located in Iran) have been collected and studied, and in this regard, 49 practical articles in Persian (2004‒2024) and 9 articles in English (2012‒2023) were analyzed. In a general classification, Kerman province was divided into four regions based on the average latitude and longitude; respectively, the northwest and southeast regions accounted for 35% and 34% of the citations and accounted for the largest amount of studies, and 73% of the sources of this research are related to studies of drought in the province, which shows the age of this phenomenon. In this research, 27% of the reviewed studies used questionnaires, and the most commonly used statistical software and analytical software were statistical-based (26%) (e.g., SPSS software) and GIS-based software (24%), respectively.
Results and discussion:
Flood and drought phenomena in Kerman Province have been increasing in intensity and frequency in recent years compared to the past, and their impact on societies cannot be denied.
Conclusions:
The summary of the obtained results shows that the biggest threat to Kerman Province is the drought phenomenon, that the whole province suffers from drought and its effects, and according to the results, the slope of the drought trend line of the Standardised Precipitation-Evapotranspiration Index (SPEI), during the statistical period of 1990‒1996 was equal to +0.046, which indicates a decrease in drought in the province, and in the statistical periods of 1997‒2010 and 2011‒2018, respectively, it was equal to -0.031 and -0.01, which indicates an increase in the severity of drought in recent years. Also, the occurrence of floods is increasing, and this phenomenon has caused the most damage in the northwest-southeast belt of the province and in the high areas.
