Uttarakhand Rivers West to East Order Explained

Understanding the geographical arrangement of rivers is crucial for studying the topography and hydrology of regions like Uttarakhand. This question asks us to identify the correct sequence of four specific rivers flowing from the westernmost part of the state towards the east.

Identifying Uttarakhand Rivers and their Locations

Let's identify the key rivers mentioned and understand their general locations within Uttarakhand:

• Yamuna River: Originates in the Yamunotri Glacier in the western Garhwal Himalayas. Its basin covers the western districts of Uttarakhand, including Uttarkashi and Dehradun.
• Bhillangana River: A significant tributary of the Bhagirathi River, it originates from the Khatling Glacier. It flows through the Tehri Garhwal district, generally moving southeast.
• Alaknanda River: A major tributary of the Ganges, it originates from the Satopanth Glacier and Bhagirath Kharak Glacier in the central Garhwal Himalayas. It flows predominantly southwest through districts like Chamoli, Rudraprayag, and Pauri Garhwal before meeting the Bhagirathi River.
• Gori Ganga River: This river originates from the Milam Glacier located in the eastern Kumaon region, specifically within the Pithoragarh district. It flows through the scenic Johar Valley.

Determining the West to East River Sequence

To determine the correct order from west to east, we need to consider the geographical position of their origins and primary flow paths within Uttarakhand:

• The Yamuna River system is situated in the westernmost part of Uttarakhand, making it the furthest west among the given rivers.
• The Bhillangana River originates in the central Garhwal region. Its source area is geographically west of the main sources of the Alaknanda River.
• The Alaknanda River also originates centrally in the Garhwal Himalayas, slightly east of the Bhillangana's origin area, and flows generally southwest.
• The Gori Ganga River is located in the eastern part of Uttarakhand, in the Kumaon region (Pithoragarh district), making it the easternmost river among the options.

Based on these geographical locations, the sequence progresses from west to east as Yamuna, followed by Bhillangana, then Alaknanda, and finally Gori Ganga.

Visualizing the River Order

The relative positions of these rivers can be clearly visualized:

Therefore, the correct order of rivers from west to east in Uttarakhand, considering their geographical placement, is Yamuna, Bhillangana, Alaknanda, and Gori Ganga.
