India is situated north of the equator between 8°4' north to 37°6' north latitude and 68°7' east to 97°25' east longitude. It is the seventh-largest country in the world, with a total area of 3,287,263 square kilometres (1,269,219 sq mi). India measures 3,214 km (1,997 mi) from north to south and 2,933 km (1,822 mi) from east to west. It has a land frontier of 15,200 km (9,445 mi) and a coastline of 7,516.6 km (4,671 mi).
The Indus is a transboundary river of Asia and a trans-Himalayan river of South and Central Asia. The 3,180 km (1,980 mi) river rises in mountain springs northeast of Mount Kailash in Western Tibet, flows northwest through the disputed region of Kashmir, bends sharply to the left after the Nanga Parbat massif, and flows south-by-southwest through Pakistan, before emptying into the Arabian Sea near the port city of Karachi.
In geography, a plain, commonly known as flatland, is a flat expanse of land that generally does not change much in elevation, and is primarily treeless. Plains occur as lowlands along valleys or at the base of mountains, as coastal plains, and as plateaus or uplands. Plains are one of the major landforms on earth, being present on all continents and covering more than one-third of the world's land area. Plains in many areas are important for agriculture. There are various types of plains and biomes on them.
Alluvium is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations.
The Indo-Gangetic Plain, also known as the Northern Plain or North Indian River Plain, is a fertile plain spanning 700,000 km2 (270,000 sq mi) across the northern and north-eastern part of the Indian subcontinent. It encompasses northern and eastern India, eastern Pakistan, southern Nepal, and almost all of Bangladesh. It is named after the two major river systems that drain the region–Indus and Ganges.
The Punjabis are an Indo-Aryan ethnolinguistic group associated with the Punjab region, comprising areas of northwestern India and eastern Pakistan. They generally speak Standard Punjabi or various Punjabi dialects on both sides.
The Ravi River is a transboundary river crossing northwestern India and eastern Pakistan. It is one of five rivers associated with the Punjab region.
Doab is a term used in South Asia for the tract of land lying between two confluent rivers. It is similar to an interfluve. In the Oxford Hindi-English Dictionary, R. S. McGregor defines it as from Persian do-āb "a region lying between and reaching to the confluence of two rivers."
An alluvial plain is a plain created by the deposition of sediment over a long period by one or more rivers coming from highland regions, from which alluvial soil forms. A floodplain is part of the process, being the smaller area over which the rivers flood at a particular time. In contrast, the alluvial plain is the larger area representing the region over which the floodplains have shifted over geological time.
The geology of India is diverse. Different regions of the Indian subcontinent contain rocks belonging to different geologic periods, dating as far back as the Eoarchean Era. Some of the rocks are very deformed and altered. Other deposits include recently deposited alluvium that has yet to undergo diagenesis. Mineral deposits of great variety are found in the subcontinent in huge quantities. Even India's fossil record is impressive in which stromatolites, invertebrates, vertebrates and plant fossils are included. India's geographical land area can be classified into the Deccan Traps, Gondwana and Vindhyan.
Jhang District is a district of Faisalabad division in the Punjab province, Pakistan. Jhang city is the capital and administrative seat of the district.
Doaba, also known as Bist Doab or the Jalandhar Doab, is the region of Punjab, India that lies between the Beas River and the Sutlej River. People of this region are given the demonym "Doabia". The dialect of Punjabi spoken in Doaba is called "Doabi". The term "Doaba" or "Doab" is derived from Persian دو آب meaning "land of two rivers". The river Sutlej separates Doaba from the Malwa region to its south and the river Beas separates Doaba from the Majha region to its north.
Majha is a region located in the central parts of the historical Punjab region, currently split between the republics of Pakistan and India. It extends north from the right banks of the river Beas, and reaches as far north as the river Jhelum. People of the Majha region are given the demonym "Majhail". Most inhabitants of the region speak the Majhi dialect, which is the basis of the standard register of the Punjabi language. The most populous city in the area is Lahore on the Pakistani side, and Amritsar on the Indian side of the border.
Montgomery District was an administrative district of the former Punjab Province of British India, in what is now Pakistan. Named after Sir Robert Montgomery, it lay in the Bari Doab, or the tract between the Sutlej and the Ravi rivers, extending also across the Ravi into the Rechna Doab, which lies between the Ravi and the Chenab. The administrative headquarters was the town of Montgomery, present-day Sahiwal. In 1967, the name of Montgomery District was changed to Sahiwal District.
Rachna Doab can be classified as one of the main regions of Punjab, Pakistan. Punjab historically has been divided into regions based on its various rivers, since the name Punjab is based on its five main rivers. Rachna doab includes all the area between the Chenab and Ravi Rivers, all the way from the Jammu Division till their confluence in Punjab, Pakistan. It lies between 30° 35' and 32° 50' N. and 71° 50' and 75° 3' E. The name was given by the Mughal emperor Akbar, by combining the first syllables of the names of the two rivers.
Marala Headworks is a headworks situated on the Chenab River near the city of Sialkot in Gujrat district in Punjab, Pakistan. A weir was first built during 1906–1912 in the British India to feed the Upper Chenab Canal, as part of the 'Triple Canals Project'. A new Marala Barrage was constructed in 1968 to feed the Marala–Ravi Link Canal in addition to the original Upper Chenab Canal.
Renala Khurd is an administrative subdivision (tehsil) of Okara District in the Punjab province of Pakistan. It is administratively subdivided into 18 Union Councils, two of which form the tehsil capital Renala Khurd.
Khādir or Khadar and Bangar, Bāngur or Bhangar are terms used in Hindi, Urdu, Punjabi and Sindhi in the Indo-Gangetic plains of North India and Pakistan to differentiate between two types of river plains and alluvial soils. Bangur and Khadir areas are commonly found in the doab regions. Some villages may have both Khadar and Bangar areas within their revenue boundaries. Bhangar soils are less fertile as they are above flood level whereas Khadar soils are more fertile as they are below the flood level. Bhanger is full of kankers while khadar soil is composed of fine silt and clay. It is fertile land as it contains alluvial soil deposited by rivers.
The topography of Pakistan is divided into seven geographic areas: the northern highlands, the Indus River plain, the desert areas, the Pothohar Plateau, Balochistan Plateau, Salt Range, and the Sistan Basin. All the rivers of Pakistan, i.e. Sindh, Ravi River, Chenab River, Jhelum River, and Sutlej River, originate from the Himalayas mountain range. Some geographers designate Plateau as to the west of the imaginary southwest line; and the Indus Plain lies to the east of that line.
Madhopur Headworks is a barrage on the Ravi River in Madhopur, just 14 km from Pathankot city in Pathankot district in the Indian state of Punjab. It is located on the border with Jammu and Kashmir. The Upper Bari Doab Canal (UBDC) off-taking from Madhopur irrigates agricultural lands in Punjab and provides water to the cities of Pathankot, Gurdaspur, Batala and Amritsar.
