Two river families with opposite habits; every dam-and-dispute question keys off the difference.
Himalayan systems
- Snow and rain fed, perennial, mature meanders, large deltas: Ganga-Brahmaputra is the largest.
- Indus system: Jhelum, Chenab, Ravi, Beas, Sutlej; Brahmaputra carries the peak discharge.
Peninsular systems
- Rain fed, seasonal, straight courses on hard rock.
- East flowing Godavari, Krishna, Kaveri build deltas; west flowing Narmada and Tapi run rift valleys to estuaries.
Treaties worth one mark
- Indus Waters Treaty 1960; Ganga treaty with Bangladesh 1996.
- Cauvery: SC 2018 formula; Krishna and Godavari tribunals under re-adjudication.
