Kerala's west-flowing rivers exhibit distinct hydrological characteristics compared to major peninsular rivers. Which of the following statements accurately describes a key feature of these rivers and its associated socio-economic implication for the state?

Accepted Answer

B. Originating from the high ranges of the Western Ghats, their steep descent leads to significant hydroelectric power potential, but also contributes to rapid sediment transport and vulnerability to flash floods. — West-flowing rivers in Kerala originate from the steep slopes of the Western Ghats, resulting in high gradients and rapid flow. This characteristic is highly advantageous for hydroelectric power generation, a major energy source for Kerala. However, the steep gradient and high velocity also lead to significant soil erosion, sediment transport, and make these river basins prone to flash floods, especially during intense monsoon rainfall.

Answer

A. Their long courses and gentle gradients facilitate extensive inland navigation and large-scale irrigation projects in the coastal plains.
