The drainage network of Punjab is characterized by seasonal fluctuations tied to precipitation patterns in the Himalayas. Which physiographic process is primarily responsible for the formation of bluffs and meanders along the lower courses of rivers like the Sutlej and Beas within the state?

💡 Solution & Explanation

As rivers enter the flat alluvial plains of Punjab, their gradient decreases significantly, causing them to shift from vertical downcutting to lateral erosion and sediment deposition, which naturally creates meandering channels and river bluffs. Rift valley faulting does not characterize the tectonic setting of the Punjab alluvial plains. Lacustrine wave action is irrelevant since Punjab rivers flow through open fluvial channels rather than large static lakes. Glacial processes are confined to the distant Himalayan source regions and do not operate in the plains where meandering occurs. River morphology studies assist in civil engineering and flood forecasting.
