Abstract EN

Irregular distribution, temporal and spatial distribution, and heavy rainfall are among the characteristics of arid and semi-arid regions, which in some cases lead to droughts and sometimes floods.

Iran has a dry and semi-dry climate, and the amount of rain is uneven, which led to climate change, especially droughts and floods, and has become a major concern for the country's authorities these days.

Accordingly, it is necessary to identify solutions to reduce the damage caused by such accidents, which we will focus on in this study, with a focus on the Yasuj region.

The main method of this research was applied, given its nature, in the form of an applied purpose and in an analytical descriptive form and accordingly, in this study, in addition to the correct depiction of crisis management and rainfall management, efforts were made to address the causes of weather hazards.

The results were determined by using precipitation data in long-range Yasug in the Excel environment during a precision test (ran test) and a compatibility test (macOS).

According to Wembley formula, 1293.5 mm of rain occurred in Yasuj during the 32-year return period.

During the 31-year statistical period (1987-19-2017), according to the SPI index for 13 years, we experienced droughts (moderate 8 years, average 3 years, severe and very severe each year.
