Energy and Water Saving on the Pumping Stations of Karshi Main Canal

Background

The western half of the Kashkadarya region of Uzbekistan is occupied by a vast sand-bordered plain with large reserves of irrigable land called Karshi steppe.

The Karshi steppe occupies the plain of South-Western Uzbekistan, with a total area of ​​13.6 thousand km². The Karshi steppe in the north and northeast runs along the foot of the Terek-Baba and Zirabulak Mountains; in the west, approximately along the route of the Amu-Bukhara Canal to Lake Karabulak; in the south-west and south along the border between Turkmenistan and Uzbekistan, and in the south-east and east about along the route of the Karshi Main Canal to the city of Karshi and further north (skirting from the west of Mount Kongurtau), almost along the meridian to the Zirabulak mountains.

On the territory of the Karshi Steppe, due to the relief, there are the Karshi Steppe itself in the north, the Nishan Steppe in the south and the irrigated oasis on the Kashkadarya River.

In the southwest, the steppe passes into vast areas of sand. This is the southern tip of the Kyzylkum – the sandy desert of Sundukli, used as pasture land for Karakul sheep.

The Karshi Steppe is characterized by a very short cold winter with little atmospheric precipitations and a long hot summer. Spring is relatively unstable, with a small amount of precipitations per year. Autumn is warm, mostly dry. In the Karshi steppe, there is intense wind activity in the form of wind and dust storms, blowing mainly from the north and north-west.
