Which technology enables real-time flood forecasting using rainfall data and river gauge measurements?
- Hydrological Modeling
- Weather Radar
- Satellite Altimetry
- All of these
Answer: All of these
Flood forecasting integrates: hydrological models (rainfall-runoff simulation), weather radar (precipitation estimation), satellite altimetry (river levels), and IoT sensors (real-time gauges). CWC and IMD operate systems for major river basins. Critical for early warning and disaster risk reduction questions.
