Q2. Examine the role of monsoons in shaping India’s hydrological regimes. Analyse how spatial and temporal variability in rainfall affects surface and groundwater systems. What measures can be taken to mitigate the impacts of uneven rainfall on regional water availability? (15 M)
Difficulty Level: Medium
Reference: TH
Why the question: IMD report showing above-normal but highly uneven monsoon rainfall across Indian regions, which has direct implications on India’s water availability, hydrology, and regional imbalances. Key Demand of the question: The question requires explaining how the monsoon drives India’s hydrological systems, analysing how spatial-temporal rainfall variations affect surface and groundwater, and suggesting practical ways to mitigate the impact of such uneven rainfall on regional water resources. Structure of the Answer: Introduction: Briefly introduce India’s monsoon-dependent hydrology and the high seasonal concentration of rainfall shaping its water systems. Body: Role of monsoons in shaping hydrological regimes – Mention seasonal river flows, aquifer recharge, and reservoir filling cycles. Impact of spatial and temporal variability – Note runoff inefficiency, groundwater stress, crop disruption, and regional imbalances. Mitigation measures – Suggest steps like water harvesting, micro-irrigation, watershed development, and hydro-data integration. Conclusion: End by stressing the need for a region-specific hydrological strategy to build long-term resilience to monsoon unpredictability.
