River Monitor for Insurers & reinsurers

Independent, satellite-based monthly views of reservoir storage and catchment rainfall for exposure and claims context.

What you get

• Monthly radar water-area history from 2017 for major Mekong dams, method published
• Catchment rainfall anomalies from ERA5 reanalysis
• GIS exports (GeoJSON, KML, DXF) and CSV for your own models
• Custom one-off reports for a named dam or river reach

What our accuracy tests actually show

• Our radar-measured reservoir area tracks independent SWOT satellite water heights well at some dams and poorly at others: correlation r = 0.85 (Xiaowan), 0.62 (Dachaoshan), 0.34 (Nuozhadu), 0.29 (Manwan), 0.03 (Jinghong).
• Our dry-season outlook is low confidence: held-out rank correlation 0.45 against the Chiang Saen gauge (error 0.48 vs 0.69 for a naive baseline).
• Catchment rainfall is only a weak guide to reservoir behaviour (r 0.10–0.34). SWOT itself reads 2–4 m low at low reservoir levels.
• We have no proven skill at forecasting downstream flows. Alerts are monthly, not real-time. Small dams are low confidence. Nile sites are not yet validated.

We are an early-stage, independent service. We don't yet have named customers or testimonials and won't pretend otherwise.
