How are the floods in Eastern India different from the ones in Western India?
The floods in Eastern India and Western India differ significantly in their nature and causes.
In Eastern India, states like Assam, West Bengal and Bihar experience flooding rivers that cause frequent inundation of agricultural land and human settlements. These are regular, seasonal floods that affect high flood-prone areas.
In contrast, Western India including Rajasthan, Gujarat, Haryana and Punjab experience flash floods in recent decades. These are caused partly by the pattern of the monsoon and partly due to blocking of streams and river channels by human activities. Flash floods are sudden and different from the regular flooding seen in eastern regions.
Explanation
The textbook clearly distinguishes between flood types in different regions. Eastern states like Assam, West Bengal and Bihar face traditional river flooding, while western states face flash floods - a more recent phenomenon linked to monsoon patterns and human interference with natural drainage. This distinction is important for understanding regional flood management strategies.
Solution Steps
Step 1: Identify flood types in Eastern India (flooding rivers in Assam, West Bengal, Bihar)
Step 2: Identify flood types in Western India (flash floods in Rajasthan, Gujarat, Haryana, Punjab)
Step 3: Compare causes - regular flooding vs flash floods due to monsoon pattern and human activities blocking river channels
