The landscape of the province is diverse; there are a lot of river valleys, foothills, 
mountains and rivers. The main rivers are the Surkhandarya, Sherobod, Tupalang, 
Sangardak rivers. Termez city lies on the right bank of the Amudarya river, which is the main 
surface water source. Annual run-off of this river varies from 3,050 m3/sec to 1,410 m

approximately 5 g/l, of which 40% are sand particles (1.0 to 0.05 mm). Average sediment 
transport is 2 to 4 kg/m3, with summer peaks up to 10 kg/m3. The main hydro-geographical 
network consists of manmade irrigation and drainage canals. All irrigated croplands in the 
province are served by this irrigation system, which is fed from the Amudarya river. 
Underground water of the South Surkhandarya groundwater deposit is used for the water 
supply of Termez district. The water salinity is 0.4 g/l.
Soils
259. 
Surkhandarya province occupies the extreme southern position within Uzbekistan. 
The system of mountain ranges separates the region from the eastern and northern parts of 
Central Asia. The best contact of air flows occurs from the west and south. All this determines 
the specific climate of the region. A t the same time, natural conditions are very diverse within 
the province. There are areas with a mountainous, semi-desert climate. According to the 
adopted soil-climatic zoning scheme, the zones of light brown high mountain soils, mountain- 
brown soils, gray soils (dark, typical, light) in the vertical zoning system and an arid zone in 
the latitudinal zoning system are distinguished within the boundaries of the Surkhandarya 
province.
