Gujarat, situated on the western coast of India, is endowed with a network of rivers that significantly contribute to its geographical, cultural, and economic landscapes. The rivers of Gujarat are categorized into three main river systems based on their origin and flow: west-flowing rivers, east-flowing rivers, and seasonal rivers. Despite being a semi-arid region, these rivers play a pivotal role in sustaining the agrarian economy, promoting biodiversity, and supporting the livelihoods of millions.
Geographical Distribution of Rivers in Gujarat
Western Flowing Rivers
These rivers drain into the Arabian Sea, defining the western coastline of Gujarat.
Major rivers in this category include the Narmada, Tapi, Mahi, and Sabarmati.
Eastern Flowing Rivers
These rivers drain toward the eastern regions and are relatively smaller.
Rivers like Damanganga and Par contribute to this category.
Seasonal Rivers
Found primarily in the arid regions of Kutch and Saurashtra, these rivers flow during the monsoon and dry up afterward.
Examples include the Shetrunji, Bhadar, and Saraswati rivers.
