The global river data backfill

One personal token opens the global broker view. Provider rights and attribution still apply.

Research archive. Terms do not permit RiverData to republish the observations as a public operational feed.

Use as a labelled model layer. Confirm downstream licensing before redistribution.

Already supplies RiverData model cells through Open-Meteo.

Global topology and catchment attributes, not current observations.

RiverData progressively loads the global reservoir inventory.

Best open global dam and barrier foundation. Merge by provider IDs and spatial confidence, never by name alone.

Sparse global satellite stations. Label as an estimate rather than a physical gauge.

Free registration and request limits. Level is not interchangeable with discharge.

Useful fallback where national services are closed.

National weekly CSV archives and station catalogue.

The modern API requires approved credentials. Bulk portal downloads remain available.

Roughly 6,000 stations. Rate controls require a staged national backfill.

WMO identifies the stewards, but no national reusable machine feed was verified for these island states.

One public CWC resource is connected. The national catalog exposes many more state and telemetry CSV resources that need automated discovery.

National portal is extensive, but no stable documented public API was verified.

Official Open API exists. Service timed out from the RiverData build environment during verification.

RiverData connects the national Internet of Water river and drainage station feed, retaining the reporting authority and native basin name. WRA labels real-time telemetry as raw and not quality controlled.

Documented API covers hydromet, dams, forecasts and water quality. The service refused connections from the build environment during verification.

National real-time tables and exports are public. A supported API was not verified.

An official API specification is published. Verify credentials, rate limits and reuse terms before production.

Data is fragmented across national and basin portals. No single documented anonymous national API was verified.

China has extensive national, provincial and basin data. No complete anonymous national operational API was verified.

Near real-time stage and flows, verified history, and weekly status for roughly 210 dams.

Some national portals exist, but regional completeness, stable APIs and reuse rights need direct confirmation.

These networks are already connected individually and remain attributed to their national or regional publishers.

Integrated dated Thai river observations, Bangkok canal levels and flows, and measured rainfall. Chao Phraya uses 20 reviewed main-stem sensors with separate minimum-bank and critical-MSL references. Date-range history backfilled from 2021 through 26 September 2026: 3,524,236 source observations summarized into 36,438 station-days, retaining daily minima, maxima, sample means and counts. HDA006 and HDA009 begin in April 2025; missing dates remain gaps. Sensor threshold exceedance is distinct from satellite-detected flood extent.

Public rolling-window summaries of population, buildings, roads, hospitals, schools and crop exposure. Acquisition date and population year are not supplied.

Approximately 250 m two-day flood composite. Cloud and classification limitations apply. Sampled detected flood cells support population and facility overlays.

2025 Global2 population model at 100 m, summed within sampled NASA detected flood cells. Estimates are residential exposure, not reported affected or displaced counts.
