Key Points

• The Mississippi River forms a "bird-foot" delta at its mouth as it empties into the Gulf of Mexico.
• The bird-foot delta is characterized by multiple distributaries (smaller branches of the river) that extend outward, resembling the toes of a bird's foot.
• This type of delta formation occurs when sediment deposition dominates over wave erosion, allowing the river's distributaries to extend far into the body of water.
• The Mississippi Delta is one of the most well-known examples of this type of formation and plays a significant role in the ecosystem and economy of the region.

Important Points

• The "bird-foot" delta is a unique geomorphological feature and is different from triangular or arcuate deltas, which are shaped more symmetrically.
• The Mississippi River's long history of sediment deposition has created rich agricultural lands and wetlands in its delta region.
• The delta region is also critical for wildlife, serving as a habitat for numerous bird species and aquatic organisms.
• However, human activities such as dam construction and levees have impacted the natural sediment flow, leading to land loss in the delta area.

Additional Information

• Danube: The Danube River forms a delta as it empties into the Black Sea, known as the Danube Delta. Unlike the Mississippi, its delta is more triangular or arcuate in shape and is one of the most biodiverse regions in Europe.
• Niger: The Niger River forms an inland delta in Mali and a traditional delta where it empties into the Atlantic Ocean. The Niger Delta is a vast wetland area and is known for its oil resources rather than for its geomorphological structure.
• Nile: The Nile River forms a classic arcuate delta as it empties into the Mediterranean Sea. It is one of the world's most famous deltas and has been the cradle of civilization for millennia.

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.

  • (i) Sei – Padrn village of Udaipur is its origin and joins Sabarmati in Gujarat.
