Concept notes: Kolkata, the capital of West Bengal, has an extensive network of canals that serve as a crucial part of its drainage system. During heavy rains, these canals can become overwhelmed, leading to various issues, including the clogging of canals by garbage, which exacerbates flooding and pollution.
Explanation: Kolkata, the capital city of West Bengal, is known for its extensive network of canals that serve as a vital part of its drainage system. These canals are designed to manage the flow of water during the monsoon season, which is characterized by heavy rainfall. However, the canals face significant challenges during these periods, particularly due to the accumulation of garbage and debris.
The primary issue with the canals during heavy rains is the clogging caused by garbage. This garbage can include plastic waste, discarded household items, and other debris that are washed into the canals. The accumulation of this waste can obstruct the flow of water, leading to a buildup of water in the canals and exacerbating flooding in the surrounding areas. This clogging not only affects the drainage capacity of the canals but also contributes to environmental pollution, as the stagnant water can become a breeding ground for mosquitoes and other pests.
The clogging of canals by garbage is a significant environmental and public health issue in Kolkata. It highlights the need for better waste management practices and regular maintenance of the canal system. Efforts to clean the canals and prevent the accumulation of garbage are crucial to maintaining the effectiveness of the drainage system and reducing the risk of flooding during the monsoon season.
In contrast, options such as people swimming in the canals, riding jet skis, or planting rice are not practical or common uses of the canals. The primary function of the canals is to manage water flow and prevent flooding, and recreational activities or agricultural use would not align with this purpose. Additionally, the presence of garbage and pollutants in the canals makes them unsuitable for such activities.
Understanding the challenges faced by the canal system in Kolkata during heavy rains is essential for addressing urban drainage issues and improving the overall quality of life in the city. Effective waste management and regular maintenance of the canals are key strategies to mitigate the problems associated with clogging and flooding.
