(i) Deltas are formed in the coastal areas where there is gentle slope, because the rivers slow down forming distributaries and channels.
(ii) The western coast bordering the Western Ghats are by and large rocky coasts having a narrow width.
(iii) Many short and swift seasonal rivers originate from the steep western slopes of the Western Ghats.
(iv) As the rivers flow through steep slopes, their velocity increases. So there is very little deposition made by them.
(v) Hence, there are no deltas on the western coast of India.
