Q5. Explain how sedimentation and changing river flows are affecting the health of Indian estuaries. (10 M)
Difficulty Level: Medium
Reference: InsightsIAS
Why the question The growing concerns about sedimentation and altered river flows caused by human interventions and natural processes, which are threatening the ecological and economic health of estuaries in India. Key Demand of the question The question requires an explanation of how sedimentation and changing river flows affect the health of Indian estuaries, with a clear focus on ecological consequences, water dynamics, and associated impacts. Structure of the Answer Introduction Briefly define estuaries and their importance as transitional zones between rivers and seas, while highlighting how they are vulnerable to sedimentation and changing river flows. Body Impact of sedimentation on estuaries: Suggest how sedimentation reduces water depth, disrupts habitats, and increases turbidity, impacting biodiversity and fisheries. Impact of changing river flows: Indicate how dams and water diversions cause reduced sediment transport, salinity imbalances, and deltaic erosion, altering the ecological equilibrium of estuaries. Conclusion Suggest a solution-oriented conclusion emphasizing integrated river basin management, sustainable water usage, and habitat restoration as measures to protect India’s estuaries.
