East Flowing Rivers Draining into the Bay of Bengal

Introduction:
East flowing rivers in India are those rivers that originate from the western ghats and flow towards the east, eventually draining into the Bay of Bengal. These rivers are known for their large size and extensive drainage basin.

Large Drainage Basin:
The east flowing rivers have a comparatively large drainage basin due to the presence of the Western Ghats. The Western Ghats serve as a natural barrier that captures the rainfall from the southwest monsoon, resulting in the formation of numerous rivers. The rivers originating from the Western Ghats have a wide catchment area, which contributes to their large size.

Topography and Slope:
The topography and slope of the land also play a significant role in the size of these rivers. The Western Ghats have steep slopes, which facilitate the rapid flow of water. As a result, the rivers flowing from these ghats carry a substantial volume of water, making them larger in size.

Monsoon Rainfall:
The east flowing rivers receive heavy rainfall during the southwest monsoon, which further adds to their size. The southwest monsoon winds blow from the Arabian Sea towards the Indian subcontinent, bringing abundant rainfall to the region. This rainfall replenishes the rivers and contributes to their increased flow.

Examples of East Flowing Rivers:
Some prominent examples of east flowing rivers are the Godavari, Krishna, Kaveri, Mahanadi, and Brahmaputra. These rivers have extensive drainage basins and contribute significantly to the freshwater inflow into the Bay of Bengal.

West Flowing Rivers Draining into the Arabian Sea

Introduction:
West flowing rivers in India are those rivers that originate from the western slopes of the Western Ghats and flow towards the west, eventually draining into the Arabian Sea. These rivers are relatively smaller in size compared to their east flowing counterparts.

Small Drainage Basin:
The west flowing rivers have a smaller drainage basin compared to the east flowing rivers. The Western Ghats act as a barrier that captures most of the rainfall, resulting in fewer rivers flowing towards the west. The smaller number of rivers contributes to the smaller size of their drainage basins.

Topography and Slope:
The topography and slope of the land also influence the size of these rivers. The western slopes of the Western Ghats have gentler slopes compared to the eastern slopes. This gradual descent leads to a slower flow of water and reduced volume, resulting in smaller rivers.

Less Rainfall:
The west flowing rivers receive comparatively less rainfall compared to the east flowing rivers. As the southwest monsoon winds bring most of the rainfall to the east coast, the western slopes of the Western Ghats receive less precipitation. The reduced rainfall results in a lesser volume of water in these rivers, contributing to their smaller size.

Examples of West Flowing Rivers:
Some examples of west flowing rivers are the Narmada, Tapi, and Sabarmati. These rivers have smaller drainage basins and drain into the Arabian Sea in western India.

Conclusion:
In conclusion, the east flowing rivers draining into the Bay of Bengal have larger drainage basins, receive higher rainfall, and have steeper slopes, resulting in their larger size. On the other hand, the west flowing rivers draining into the Arabian Sea have smaller
