Rivers originating from Western ghats are short and swift and hence they form Deltas.
Answers
Answer:
Points to remember:
The Western Ghats are just close, continuous and parallel to the western coast.
The Deccan Plateau slopes gradually towards east.
Deltas are formed due to accumulation of sediments brought by the rivers.
Stream velocity decreases as the slope decreases.
The rivers that originate in the Western Ghats (WG hereafter), either flow eastwards or westwards.
Map of Western Ghats, source: Down to Earth . To your right is East.
The west flowing rivers are shorter than the east flowing rivers. There is a high gradient for the west flowing rivers than the east flowing rivers. Therefore, being very close to coast and with high gradient, there are less opportunities for rivers to become wide (spread out) towards the sea unlike east flowing rivers.

Rivers originating from the western ghats are short and swift, and hence they form estuaries and not deltas.... Many east flowing Rivers using from the western and Eastern ghats meet this coast. since the slope of the land is gentle, Rivers flow at lower velocities and deposit the sediments brought with them at the coast.
