Zoning of the degree of risk in the southern areas of Khuzestan province in the conditions Climate change with emphasis on industrial infrastructure

 climate change can be considered one of the biggest environmental challenges of the recent era, which indicates unusual changes in the internal climate of the earth's atmosphere and its consequences in different parts of the globe, which is a serious threat to the environment. The purpose of this research is to prepare a vulnerability zoning map of infrastructures in the southern regions of Khuzestan in the conditions of climate change.

 for this purpose, using previous sources and interviews with experts, eleven variables of total annual precipitation, average temperature of hot and cold season, the trend of maximum precipitation of more than 5 mm per day, the number of dust codes, the occurrence of heat waves above the 95th percentile, precipitation changes, displacement of coastline, underground water changes, floods and inundation and temperature changes during 2019 to 2019 were investigated. By using two trend analysis tests, i.e. Sence slope estimator trend analysis test and Mann-Kendall trend analysis test, the trend of the 32-year time series of these elements during the basic statistical period (1985-2017) was investigated.

 The southern parts of the studied region of Khuzestan had an average temperature of more than 38 degrees Celsius per year, while the northern and central parts of the studied region had a temperature of more than 38.5 degrees Celsius per year.The southern part of Khuzestan has an annual rainfall equivalent to more than 273 mm per year, while the southern parts of the studied area have less than 200 mm of rainfall per year and in some cases about 156 mm per year.

 The results show that high and very high risk areas cover 80% of the region.
