Which season does the Teesta River experience its highest flow due to ...
The Teesta River's highest flow occurs during the summer months, specifically from June to September. This is primarily due to the heavy monsoon rains that contribute significantly to the river's water volume, along with the melting of glaciers in the Himalayas. Notably, this season can lead to increased flooding and changes in the river's course, which are vital considerations in managing water resources and navigation in the region. Interestingly, the Teesta is also known for its diverse ecosystem, supporting various flora and fauna along its banks.

Understanding the Teesta River Flow
The Teesta River, which flows through India and Bangladesh, experiences its highest flow during the summer months primarily due to two key factors: monsoon rains and glacial melt.
Monsoon Rains
- The Indian summer monsoon typically begins in June and lasts until September.
- During this period, the region receives heavy rainfall, significantly increasing the river's volume.
- The intense precipitation in the catchment area contributes to rapid runoff, leading to elevated water levels in the river.
Glacial Melt
- The Teesta River originates from the glaciers in the Himalayas.
- As temperatures rise during the summer, the melting of glaciers adds substantial water to the river.
- This meltwater, combined with monsoon runoff, results in the highest flow rates.
Seasonal Impact
- The combination of monsoon rains and glacial melt peaks in the summer, making it the season with the highest discharge.
- This seasonal flow is crucial for agriculture, hydropower generation, and maintaining the ecological balance in the river basin.
Conclusion
In summary, the Teesta River's highest flow occurs in summer due to the synergistic effects of monsoon rains and glacial melt. Understanding this pattern is essential for various sectors, including agriculture, water resource management, and disaster preparedness.
