Which of the following best explains why the West Coastal Plains of India are characterised by numerous estuaries instead of extensive deltas?
Rivers are short, steep, and fast-flowing
The West Coastal Plain is a narrow strip (about 50-100 km wide) lying between the Western Ghats and the Arabian Sea.
Rivers such as the Narmada, Tapi, Mandovi, Zuari and Periyar originate close to the coast, descend the steep western scarp of the Ghats and reach the sea over very short distances with high gradient and swift flow.
Because of this short, steep, fast-flowing character they have neither the time nor the low-gradient tract needed to drop sediment and build up broad deltas; instead their mouths are drowned by tidal action, forming estuaries and rias.
Rivers of the east coast (Ganga, Godavari, Krishna, Kaveri, Mahanadi) are long, slow and sediment-laden and therefore build extensive deltas – the exact opposite of the west-coast situation.
Hence, the answer is that the rivers are short, steep, and fast-flowing.
