Arrange the following left-bank tributaries of the Ganga River in sequence according to the location of their confluence points with the Ganga, moving from West to East:

  1. 1Ramganga River
  2. 2Gomti River
  3. 3Ghaghara River
  4. 4Gandak River
  5. 5Kosi River

Cevap

The correct sequence from West to East is: Ramganga River → Gomti River → Ghaghara River → Gandak River → Kosi River.
The Ganga receives several major left-bank tributaries originating from the Himalayas and the northern plains. Following the flow of the Ganga from west to east across Uttar Pradesh and Bihar, the confluence points occur in the order: Ramganga River (Kannauj, UP), Gomti River (Saidpur/Ghazipur, UP), Ghaghara River (Chhapra, Bihar), Gandak River (Sonepur/Patna, Bihar), and Kosi River (Kursela/Katihar, Bihar).

Adım Adım Çözüm

1
Identify the regional positions and points of origin for each Ganga left-bank tributary.
Ramganga originates in Uttarakhand; Gomti in Pilibhit (UP); Ghaghara in Tibet/Nepal Himalayas; Gandak in Nepal Himalayas; Kosi in Tibet/Nepal border region.
Tracking origins helps establish the general longitudinal layout of the rivers across northern India.
2
Trace the confluence location of each tributary with the main stem of the Ganga River.
Ramganga meets Ganga at Kannauj (UP); Gomti meets Ganga near Saidpur/Varanasi (UP); Ghaghara meets Ganga near Chhapra (Bihar); Gandak meets Ganga at Sonepur/Patna (Bihar); Kosi meets Ganga at Kursela (Katihar, Bihar).
Confluence points provide precise spatial anchors along the west-to-east flow of the Ganga River.
3
Order the confluence locations by their longitudes from West to East.
Kannauj (~79.9° E) → Saidpur (~83.2° E) → Chhapra (~84.6° E) → Sonepur (~85.2° E) → Kursela (~87.2° E).
This spatial alignment matches the requested West-to-East direction.
