Supporting evidence — 5 representative gaps

• Assessment of SWOT water surface elevations for flood monitoring of a narrow river ( < 50 m width) (2026) · Hydrology and earth system sciences · doi

  The study highlights the challenge of obtaining reliable observations of water surface elevation in narrow rivers. The paper notes the limitation of ground-based observations in data-scarce contexts. The study identifies the need for accurate and reliable flood monitoring data to support risk management and decision-making.

• Integrating historical archives and geospatial data to revise flood estimation equations for Philippine rivers (2025) · Hydrology and earth system sciences · cited 2× · doi

  The lack of data in many regions, especially in the Global South, limits the choice of statistical methods for flood estimation. The paper notes that uncertainty will be greater for sites with records of less than 20 years. The use of the index flood approach requires careful consideration of the controls at national and regional scales.

• Flood Susceptibility and Risk Assessment in Myanmar Using Multi-Source Remote Sensing and Interpretable Ensemble Machine Learning Model (2026) · ISPRS International Journal of Geo-Information · cited 8× · doi

  The study identifies a need for a robust scientific basis for flood management and spatial planning in monsoon-affected areas. There is a lack of effective methods for flood susceptibility and risk assessment in data-scarce regions. The study aims to address the gap by demonstrating the applicability of multi-source remote sensing for flood assessment.
