Introduction:
River avulsion is a natural process in which a river changes its course by abandoning its existing channel and creating a new channel. It is a significant geomorphic process that shapes the landscape and can have profound impacts on the surrounding environment.

Explanation:
Let us analyze each statement to determine its correctness:

Statement 1: It is a typical feature associated with the rivers of temperate regions.
River avulsions are not limited to temperate regions; they can occur in any geographic region where rivers flow. The occurrence of river avulsions is influenced by various factors such as the river's sediment load, river gradient, and tectonic activity. Therefore, statement 1 is incorrect.

Statement 2: It occurs less frequently, only once a decade or century.
The frequency of river avulsions varies depending on the specific river and its geomorphic characteristics. While some rivers may experience avulsions once every few decades or centuries, others may undergo avulsions more frequently. The frequency of avulsions is influenced by factors such as sediment deposition, river channel stability, and human activities. Therefore, statement 2 is incorrect.

Conclusion:
Neither statement 1 nor statement 2 is correct. River avulsions can occur in any region and their frequency varies depending on multiple factors. It is important to understand the factors influencing river avulsions to effectively manage and mitigate their impacts on the surrounding environment.

  • Avulsion refers to the phenomenon of change in the course of river flow causing the abandonment of the old established river channel and formation of a new channel.
    • Rivers lining tropical and desert regions are more prone to avulsions. Hence, 1 statement is not correct.
  • Avulsions occur less frequently, only once a decade or century, or even less. Hence, statement 2 is correct.
    • The rare occurrence of avulsions makes them less discussed despite their catastrophic effects as compared to more frequent extreme weather events and the continuous effect of sea-level rise.
