Lowlands are widespread in the western and part of the southern part of the region, adyrs are widespread except in the northern part, where there are only high mountains. Almost all the territory where the high mountain systems, the eastern Tien Shan, the Karzhantau ridge, the Pskem Mountains, the Ugam ridge and the Chatkal ridge are located, is occupied by mountains. The heights in the district accordingly increase in direction from west to east and from south to north. The southern and western parts of the region are on average 1000 meters above sea level. The rest of the region where the highlands prevail, is located at an altitude of 1,200 to 4,000 meters above sea level. The highest point of the area is the peak of the Adelung Pskem ridge with an altitude of 4301 meters. In the second place in height, the mountain is another peak of the Pskem ridge - Beshtor with a height of 4299 meters. In addition to the peaks and peaks listed above, there are many high mountains and peaks in the district, which are between 1,000 and 4,000 meters above sea level. The largest and most significant peaks and peaks of the region: Aktash, Big Chimgan, Kyzylnur, Mingbulak, Pulatkhan and others. Car passes pass through many relatively high mountains. The hills are formed mainly by sandstones and loess. The foot of many mountains are mainly composed of slate and granite. The territory of the region is included in a seismic zone and annually from 5 to 8 or more earthquakes of various types occur in the region.
Watercourses (sais), some of which turn into rivers, flow down almost from all mountain ranges. The main watercourses in the district are tributaries of the Chirchiq River. The largest of them are the Beldersay, the Pskem, the Ugam, the Koksu, and the Chimgansai. The Chatkal River also flows through the district, though it is sometimes considered to be a fork of the Chirchiq. Most of the district's rivers flow into reservoirs, including the Charvak Reservoir.Their waters are used for irrigated agriculture, practiced on gentle slopes at the foot of the mountains. Groundwater is located in the district at a depth of 2-3 m to 6 to 20 meters.

With an area of 238,397 km2 (92,046 sq mi), Romania is the twelfth-largest country in Europe. Located in Southeastern Europe, bordering on the Black Sea, the country is halfway between the equator and the North Pole and equidistant from the westernmost part of Europe—the Atlantic Coast—and the most easterly—the Ural Mountains. Romania has 3,195 kilometres (1,985 mi) of border. Republic of Moldova and Ukraine lie to the east, Bulgaria lies to the south, and Serbia and Hungary to the west. In the southeast, 245 kilometres (152 mi) of sea coastline provide an important outlet to the Black Sea and the Atlantic Ocean.
Syria is located in Western Asia, north of the Arabian Peninsula, at the eastern end of the Mediterranean Sea. It is bordered by Turkey to the north, Lebanon and Israel to the west and southwest, Iraq to the east, and Jordan to the south. It consists of mountain ranges in the west and a steep area inland. In the east is the Syrian Desert and in the south is the Jabal al-Druze Range. The former is bisected by the Euphrates valley. A dam built in 1973 on the Euphrates created a reservoir named Lake Assad, the largest lake in Syria. The highest point in Syria is Mount Hermon on the Lebanese border. Between the humid Mediterranean coast and the arid desert regions lies a semiarid steep zone extending across three-quarters of the country, which receives hot, dry winds blowing across the desert. Syria is extensively depleted, with 28 percent of the land arable, 4 percent dedicated to permanent crops, 46 percent utilized as meadows and pastures, and only 3 percent forest and woodland.
Tajikistan is nestled between Kyrgyzstan and Uzbekistan to the north and west, China to the east, and Afghanistan to the south. Mountains cover 93 percent of Tajikistan's surface area. The two principal ranges, the Pamir Mountains and the Alay Mountains, give rise to many glacier-fed streams and rivers, which have been used to irrigate farmlands since ancient times. Central Asia's other major mountain range, the Tian Shan, skirts northern Tajikistan. Mountainous terrain separates Tajikistan's two population centers, which are in the lowlands of the southern and northern sections of the country. Especially in areas of intensive agricultural and industrial activity, the Soviet Union's natural resource utilization policies left independent Tajikistan with a legacy of environmental problems.
