Climate
Darreh Shahr County has a warm climate with hot dry summers and mild wet winters. July–August maximum daily temperature can as high as 48 °C (118 °F) during heat waves, which are frequent in summer due to proximity to the Iraqi desert. Winters are generally mild but occasionally goes below freezing.[10]
The long-term average annual precipitation is 465.1 mm (18.31 in) at Darreh Shahr Weather Station. The lowest annual precipitation happened during the farming season of 2007–2008 with a figure as low as 188.2 mm (7.41 in). The highest annual precipitation used to be 872.7 mm (34.36 in) in 1990–1991, after which, a deadly flood ensued. This record was broken in 2018–2019 with 1,046.5 mm (41.20 in), which again resulted in a heavy flooding in southwestern Iran.[10]
There is almost no precipitation through the months of June to September. Darreh Shahr used to receive snow once or twice a year in the past, but nowadays it has become less and less likely thanks to global warming.[10] Hail and lightning storms are not uncommon in Fall and Spring and have devastating effects on crops and the farming-dependent economy of the county.
Western air masses from the Mediterranean and Black Sea are cause autumn and winter rains in the province, and Sudanese and Red Sea and Saudi Arabia currents are also effective in winter and spring rains and cause warm weather in summer. The vast plains of Iraq create a low-pressure high-temperature low-humidity weather cell over the area.[11]
Seymareh landslide
In prehistoric times, a huge landslide occurred in the south eastern parts of Kabir Kuh range. The incident is described in an article on Royal Geographical Society, published in 1937 by Harrison and Falcon. Based on their observations, the landslide is 9 by 2.5 mi (14.5 by 4.0 km) in area and 1,000 to 1,500 ft (300 to 460 m) in thickness; amounting to a body of material of about 30 km3 (7.2 cu mi), some of which is found around 10 mi (16 km) from their original location. The reason for this colossal event is very likely to have been a catastrophic earthquake. Due to its enormity, the Seymareh Landslide is believed to be the largest one recorded in the eastern hemisphere.[12]

Each of its arches is placed at 5.5 m (18 ft) intervals from each other.[30] This Sassanid bridge has been constructed in the confluence of the Seymareh and Kashkan rivers. Although it has been repaired several times during the past, it is almost in a ruined state now.[31]

The earthenware objects found in the first floor are simple. Moreover, some flint blades and carved stones have been discovered there as well.[34]
Koozeh Garan Hill is about 5.5 kilometers from Tikhan Hill, and is larger and older than it. Its antiquity dates back to the late 3rd millennium BC, but its first floor dates to the Sassanid period. Some colored and engraved earthenware objects have been discovered in the basement of the building, the nature of which suggests the area to have once been involved in pottery production. Certain parts of lower floors had been allocated as burial areas. The upper graves belong to the Zoroastrian period.[35]
Cham Namesht Bridge is an 18-arch bridge constructed on the Seymareh river 4 kilometers north of Darreh Shahr facing the Chamkalan village. The antiquity of this bridge dates back to the Sassanid period, but it was used for centuries afterward. The bridge is directly connected to the remains of the Sassanid monuments in Darreh Shahr.[36]
