- A joint CBAS and IRDR China team compared domestic and international satellite imagery from 12 and 26 August 2026 to delineate water-covered areas, backflow, and river-channel widening.
- Provenance
- Produced by the International Research Center of Big Data for Sustainable Development Goals and the IRDR National Committee of China and published by IRDR.
- Validation
- Provider Published
- Uncertainty
- The brief reports mapped areas and reach lengths but does not state positional accuracy, classification uncertainty, or an independent field-validation result.
- Limitations
- The three-page rapid product focuses on remote-sensing evidence in the border and upper corridor and is not a complete assessment of downstream impacts in Nepal.
