Q. Consider the following:

1. Kosi River
2. Genhua River
3. Kamla River

Which of the above rivers is known for frequent flooding events affecting agricultural lands in Bihar?
Answer: Only 1
Notes: The Kosi River is notorious for its flooding, particularly in Bihar, where it has caused agricultural damage. It has a history of changing course and breaching embankments. The river's seasonal monsoon floods often inundate low-lying areas, affecting crops and livelihoods. Its floodplain is densely populated, making the impact on communities severe. In contrast, the Genhua and Kamla rivers are less known for such destructive flooding events.
