Q2. Illegal riverbed mining disrupts the geomorphic equilibrium of riverine systems. Explain how this affects river morphology. Assess its impact on groundwater recharge and natural springs. (10 M)
Difficulty Level: Medium
Reference: DTE
Why the question: Ongoing ecological degradation in Kashmir’s rivers like Doodh Ganga and Sukh Nag, highlighted in recent NGT rulings and environmental studies. Key Demand of the question: The question requires an explanation of how illegal mining alters river morphology and a linked assessment of its impact on groundwater recharge and natural springs, particularly in fragile Himalayan zones. Structure of the Answer: Introduction: Briefly introduce the concept of geomorphic equilibrium and highlight its disruption through anthropogenic pressures like illegal mining. Body: Mention how mining alters natural fluvial processes, causing changes in riverbed depth, bank stability, and sediment dynamics. Show how these geomorphic disturbances affect groundwater movement, reduce aquifer recharge, and sever the linkage with natural springs. Conclusion: End with a concise line on the urgent need for hydrological sustainability through scientific mining practices and stronger regulatory frameworks.
