The correct answer is Radial.

Key Points

• Radial Pattern
  • The tributaries from a summit follow slope downwards and drain down in all directions.
  • The radial drainage pattern develops around a central elevated point and is common to conically shaped features such as volcanoes.
  • Examples: Streams of the Saurashtra region, the rivers originating from the Amarkantak Mountain, Central French Plateau, Mt. Kilimanjaro.
  • The Narmada, Son and Mahanadi originate from Amarkantak Hills and flow in different directions.

Additional Information

• Dendritic
  • This is an irregular tree branch shaped pattern that develops in a terrain that has uniform lithology and where faulting and jointing are insignificant.
  • Examples: Indus, Godavari, Mahanadi, Cauvery, Krishna.
• Trellis
  • In this type of pattern, the short subsequent streams meet the mainstream at right angles, and differential erosion through soft rocks paves the way for tributaries.
  • Examples: The old folded mountains of the Singhbhum and Seine and its tributaries in the Paris basin have drainage of trellis pattern.
• Centripetal
  • In a low-lying basin, the streams converge from all sides.
  • Examples: Streams of Ladakh, Tibet, and the Baghmati and its tributaries in Nepal.

The correct answer is The Indus.Key Points

• Panchnad comprises five rivers located on the left bank of the Indus.
• They are also tributaries of the Indus river.
• They originate across the Himalayas.
• They are Ravi, Jhelum, Satluj, Beas, and Chenab.  

Additional Information

•  Indus River system:
  • It originates from a glacier near Bokhar Chu in the Tibetan region.
  • Other tributaries are the Shyok, the Gilgit, the Zaskar, the Hunza, the Nubra, the Shigar, the Gasting and the Dras.
  • In Tibet, the Indus river is known as ‘Singi Khamban'.

The drainage systems of India are mainly controlled by the broad relief features of the subcontinent. Accordingly, the Indian rivers are divided into two major groups:

1. The Himalayan rivers; and
2. The Peninsular rivers

The Brahmaputra, one of the Himalayan rivers is characterized by frequent shifting in its channel.

The Brahmaputra River System:

• The Brahmaputra rises in Tibet east of Mansarovar lake very close to the sources of the Indus and the Satluj.
• It is slightly longer than the Indus, and most of its course lies outside India.
• It flows eastwards parallel to the Himalayas.
• On reaching the Namcha Barwa (7757 m), it takes a ‘U’ turn and enters India in Arunachal Pradesh through a gorge.
• Here, it is called the Dihang and it is joined by the Dibang, the Lohit, and many other tributaries to form the Brahmaputra in Assam
• Every year during the rainy season, the river overflows its banks, causing widespread devastation due to floods in Assam and Bangladesh.
• Unlike other north Indian rivers, the Brahmaputra is marked by huge deposits of silt on its bed causing the riverbed to rise.
• The river also shifts its channel frequently.

Hence, option 2 is the correct answer.

The correct answer is Godavari.

• The largest river in peninsular India is Godavari and thus it is named Vriddha Ganga.

The correct answer is meanders.

Key Points

• Meandering River:
  • The formation of successive bends of reverse order may lead to the formation of a complete S curve called Meanders.
  • When consecutive curves of reverse order connected with short straight reaches called crossings are developed in a river reach, the river is stated to be a Meandering river.
• The meandering of a river is due to the erodibility of the bed and banks of streams.
• Causes
  • Extra turbulence is generated by excess river sediment during floods. When the silt charge is in excess of the quantity required for stability, the river starts building up its slope by depositing the silt on its bed.
  • The increase in bed slope tends to increase the width of the channel if the banks are not resistant. The banks are attacked by river water and in the process one bank is likely to be attacked slightly more than the other, causing a slight deviation in flow.
  • This slight deviation from the uniform axial flow helps in improving more and more flow towards one bank than towards the other.
  • This process continues causing one bank to be convex and another to be concave. Hence, increasing slope is also a reason for meandering.

Additional Information

• Meander parameters:
• Meander Length: It is the axial length of one mender, i.e. tangential distance between the corresponding points of the meander.
• Meander Belt: It is the distance between the outer edges of clockwise and anticlockwise loops.
• Meander Ratio: It is the ratio of the meander belt to the meander length.
• Tortuosity: It is the ratio of length along the channel (actual length) to the direct axial length.
• Crossings or cross-over: It is the shortest reach of the river, connecting two consecutive clockwise and anticlockwise loops.
