কারণ ও প্রেক্ষাপট

The Ganges-Brahmaputra-Meghna basin is a transboundary river system draining the Himalaya, Tibetan Plateau, Indian subcontinent and Bangladesh delta. The governing relationship is: Monsoon rainfall, snow and glacier melt, sediment transport and tributary convergence feed a distributary delta at the Bay of Bengal.

কীভাবে কাজ করে

Monsoon rainfall, snow and glacier melt, sediment transport and tributary convergence feed a distributary delta at the Bay of Bengal.

মূল তথ্য

• The basin crosses multiple sovereign states, making water governance transboundary.
• The rivers carry enormous sediment loads that build and rebuild the delta.
• Seasonal discharge peaks strongly during the South Asian monsoon.

প্রচলিত ভুল ধারণা

• A basin boundary is defined by drainage divides, not political borders.
• The Meghna system includes major tributary flows and estuarine channels, not one isolated stream.
