Crossing Sutlej Rail bridge near Ludhiana: Amritsar- Sealdah Express on-board
The 12380
Amritsar -
Sealdah Superfast (
Jalianwala Bagh/
W.B. Sampark Kranti) Express headed by 22565
Howrah shed WAP-4E (Medha
Vigilance Control Device, i.e.
VCD fitted and steam engine type honk) crosses the massive Sutlej (Sutudri) river near
Ludhiana Junction station enroute.
Here is some facts about this river-
The
Sutlej River (alternatively spelled as
Satluj River) (
Punjabi: ਸਤਲੁਜ, Sanskrit: शुतुद्रि, Śutudri,
Urdu: ستلج, and Hindi: सतलज) is the longest of the five rivers that flow through the historic crossroad region of
Punjab in northern
India and Pakistan. It is located north of the
Vindhya Range, south of the
Hindu Kush segment of the Himalayas, and east of the
Central Sulaiman Range in
Pakistan.
The Sutlej is sometimes known as the
Red River. It is the easternmost tributary of the
Indus River. Its source is near
Lake Rakshastal in
Tibet, China, near
Mount Kailas, and it flows generally west and southwest entering
India through the Shipki La pass in
Himachal Pradesh. In
Pakistan, it waters the ancient and historical former
Bahawalpur state. The region to its south and east is arid, and is known as
Cholistan a part of
Bahawalpur Division. The Sutlej is joined by the
Beas River in Hari-Ke-Patan, Amritsar, Punjāb, India, and continues southwest into Pakistan to unite with the
Chenab River, forming the
Panjnad River near
Bahawalpur. The
Panjnad joins the Indus River at
Mithankot.
Indus then flows through a gorge near
Sukkur, flows through the fertile plains region of
Sindh, and terminates in the
Arabian Sea near the port city of
Karachi in Pakistan.
The waters of the Sutlej are allocated to India under the
Indus Waters Treaty between India and Pakistan, and are mostly diverted to irrigation canals in
India. There are several major hydroelectric projects on the Sutlej, for example, the 1,
000 MW
Bhakra Dam, the 1,000 MW Karcham-Wangtoo and the 1,530 MW
Nathpa Jhakri Hydroelectric Dam. There has been a proposal to build a 214-kilometre (133 mile) long heavy freight canal, known as the
Sutlej-Yamuna Link (
SYL), in India to connect the Sutlej and
Yamuna rivers. However, the proposal met obstacles and was referred to the
Supreme Court.
The Sutlej was known as Śutudri in the
Vedic period, and along with all of
the Punjab rivers, is thought to have drained east into the
Ganges prior to 5 mya.
There is substantial geologic evidence to indicate that prior to
1700 BC at the latest, Sutlej was an important tributary of the
Ghaggar-Hakra River (possibly through the
Saraswati river) rather than the Indus with various authors putting the redirection from 2500-2000 BC or 5000-3000 BC Geologists believe that tectonic activity created elevation changes which redirected the flow of Sutlej from the southeast to the southwest. The mighty Saraswati then began to dry up, causing desertification of Cholistan and the eastern part of the modern state of Sindh. The desertification resulted in abandonment of numerous ancient human settlements along the banks of Saraswati. There is some evidence that the high rate of erosion caused by the modern Sutlej River has influenced the local faulting and rapidly exhumed rocks above
Rampur. This would be similar to, but on a much smaller scale then, the exhumation of rocks by the Indus River in
Nanga Parbat, Pakistan. The
Sutlej river also exposes a doubled inverted metamorphic gradient.
The source of the Sutlej is just west of
Mt. Kailash in western
Tibet. This is a roadless area, and was first explored by kayak and raft by
Russian and
German teams in 2004. The largest modern industrial city along the Sutlej banks is Ludhiana.
