Question 8

Kerala's west-flowing rivers are crucial for the state's ecology and economy. However, their characteristics make them particularly vulnerable to certain environmental challenges. Which of the following is the most significant environmental challenge faced by these rivers due to their inherent nature?

Accepted Answer

B. High susceptibility to pollution from industrial and urban waste coupled with low dilution capacity during lean seasons. — Kerala's west-flowing rivers are relatively short, have steep gradients, and are predominantly monsoon-fed, leading to significant fluctuations in water volume. During the lean seasons, their reduced flow significantly lowers their dilution capacity, making them highly susceptible to pollution from the dense urban and industrial settlements along their banks. While hydroelectric potential exists due to steep gradients and salinization occurs in lower reaches, pollution due to low dilution is the most pervasive and significant challenge.

Answer

A. Limited potential for hydroelectric power generation due to their short length and steep gradient.

Answer

C. Excessive siltation and delta formation at their mouths, causing navigation difficulties for large vessels.

Answer

D. Rapid salinization of their upper reaches due to tidal ingress from the Arabian Sea throughout the year.
