## Geography
### Location

The southernmost part of the province is where the county of Kahnuj is situated. Jiroft County to the north, Hormozgan Province to the west and south, Jazmourian and Sistan-Baluchestan regions to the east, and Hormozgan Province to the west and south.

### Overview

The elevation of Kahnuj is 5.5 meters above sea level. The Beshagard Mountains, a section of the Zagros Mountains that extend towards Jazmourian and divide Kahnuj from Hormozgan Province, are situated in this county's mountainous region. In general, Kahnuj has a hot climate. Although precipitation is rare, it can occasionally take the form of torrential rain.
The only continuously flowing river in this county flows in the north and is called the Helil River. The Komsafid River, which rises in the Beshagard Mountains, is one of the seasonal rivers and descends into the Chaleh Chah Reza cavern
The unfavorable climate and neglect of agriculture have resulted in a low population in this county. However, there has been a slight increase in population and a decline in migration recently, thanks to the improvement of health, cultural, and economic conditions as well as the development of agricultural facilities. After Iran's Islamic Revolution, the Jihad-e Sazandegi (Construction Jihad), in particular, attracted the attention of officials, and effective measures were taken to improve the region's economic situation. With its rich soils and nearby underground water sources, Kahnuj County is ideal for farming and raising livestock.
