River flow
Is this river running unusually high or low for today's date, against its own record? GloFAS gives every river on Earth a daily discharge, but a number in cubic metres says nothing on its own: a river's normal June is not its normal December.
What it shows
Is this river running unusually high or low for today's date, against its own record? GloFAS gives every river on Earth a daily discharge, but a number in cubic metres says nothing on its own: a river's normal June is not its normal December. LayEarth ranks today's flow of 37 major rivers, from the Mississippi and the Amazon to the Danube, the Ganges and the Yangtze, inside a 31-day window around the same date in each of the last 18 years: a percentile, the logic river agencies use to call a high-flow warning, for every big basin at once.
Where the data comes from
Copernicus Global Flood Awareness System (GloFAS) reanalysis and forecast discharge, through the Open-Meteo Flood API; each named gauge point snapped onto the nearby ~5 km routing cell that carries the most water; recomputed every 12 hours.
Reading the map
Magenta and orange rivers run above their normal for the date, green within it, amber and brown below it; the farther from the median, the bigger the dot.
Units Discharge in m³/s. Percentile = share of the same-season days on record (±15 days around today's date, each of the last 18 years) with discharge at or below today's. Bands: ≥98 far above, ≥90 well above, 10-90 normal, ≤10 well below, ≤2 far below.
