Ghaggar-Hakra River Basin Landforms Explained

The Ghaggar-Hakra river basin, a significant geographical feature in North India, is often divided into distinct zones based on elevation and flood frequency. Understanding these classifications helps in analyzing the agricultural potential and settlement patterns within the basin.

Classifying River Basin Areas

River basins are frequently classified based on the characteristics of the land, particularly concerning the river's flow and potential for flooding. The Ghaggar-Hakra river basin is no exception. The primary distinction is often made between areas that are regularly inundated by floodwaters and those that remain relatively high and dry.

Understanding Bangar Land

The specific question asks about the higher area within the Ghaggar-Hakra river basin that does not typically flood during the rainy season. This type of landform is known as Bangar.

• Bangar refers to the older alluvial deposits found in river valleys.
• These areas are situated at a higher elevation compared to the riverbed.
• Because of their elevated position, Bangar lands are generally not affected by the annual floods, making them suitable for settlement and agriculture with less risk.
• They often consist of older, more consolidated soil.

Comparing Bangar and Khadar

It's useful to contrast Bangar with another related term, Khadar:

• Khadar represents the newer alluvial deposits found closer to the river channel.
• Khadar lands are located in the floodplains and are subject to frequent flooding during the monsoon season.
• These areas receive fresh layers of silt each year, making them very fertile but also prone to flood damage.

Ghaggar-Hakra Basin Classification

Therefore, within the Ghaggar-Hakra river basin:

• The higher, non-flooded regions are referred to as Bangar.
• The lower, flood-prone plains near the river are known as Khadar.

The option Bangar correctly identifies the higher area not flooded in the rainy season.

Other Options Analysis

• Banjar: This term usually refers to barren or unculturable land, which doesn't specifically describe the flood characteristics of a river basin area.
• Kalar: This term typically refers to saline or alkaline soil, often found in arid or semi-arid regions, and is unrelated to flood plain classification.
