Altimetry Feature Service (Water Level/Discharge)

Paste a live ArcGIS FeatureServer layer URL, service URL, or /query URL containing station geometry and water level/discharge fields. The app dynamically queries stations intersecting the selected AOI/basin; demo gauges are disabled by default.

GEOGLOWS Forecast API

GEOGLOWS River ID / Reach ID

GEOGLOWS Hydroviewer data capture: open Hydroviewer, click a stream or use Enter River ID, then paste the River ID here. The app requests 15-day forecast statistics when the API is reachable and keeps a rainfall-runoff fallback otherwise.

GloFAS Timeseries API

Google Flood API Key

GRDC Station ID

GRDC Approved Download URL

GRDC integration is for observed discharge validation. Select/download station data from the official GRDC portal under its Terms of Use, then provide the station ID or approved file URL here.

Caravan Gauge / Catchment ID

Caravan Timeseries CSV URL

Caravan is a global historical hydrology dataset for ML training, benchmark testing, calibration, and basin similarity analysis. It complements live feeds but does not replace operational nowcast sources. See the Nature paper, Zenodo dataset, and GitHub repository.

Nowcast Outputs

Run the model to view probability and flood band.

Select a basin to fetch dynamic rainfall and weather context.

Basin hydrograph integrations will appear after selecting a basin.
