Elbe model-cell comparison

The selected model-cell discharge is compared with lower-tail percentile boundaries for the same calendar month, derived from that cell's stored GloFAS climatology. P10 and P20 determine the label; the median only positions the bar.

Formulabelow model P10 if Q < model P10; model P10-P20 if model P10 ≤ Q < model P20; at or above model P20 if Q ≥ model P20

Data & provenanceGloFAS v4 via Open-Meteo · stored climatology for the selected model cell

LimitThe model value for this day is compared with this exact cell’s stored monthly GloFAS v4 climatology. Below P10, P10-P20, and at or above P20 are European model-comparison bands. P10 means the 10th percentile of that model record; it is not Q355, Q364, or a statutory minimum residual flow.

One verdict from the continental river model, and the atlas plate behind it. Model points, official gauges and reservoirs are counted separately throughout.

Within normal range26 of 101 scored European rivers are below their normal range.

19 sit under their 10th percentile and 13 over their 90th. The median scored river is at the 48th percentile of its own record.

River verdict

Each model point is placed in its own seasonal record. A river uses its scored outlet point when available; otherwise it uses the mean percentile of its scored points. The headline then counts rivers, so a river with several watch points still has one vote.

Formula

river p = outlet p, else mean(scored point p); exceptional signal if rivers below P10 ÷ scored ≥ 20%; else below-normal if rivers below P25 ÷ scored ≥ 34%; else within range

Scored rivers: 101 / 101
Below p25: 26 / 101
Below p10: 19 / 101
Median river: p48

Published result26 of 101 scored European rivers are below their normal range.

Data & provenanceGloFAS v4 discharge via Open-Meteo. Point scores use only the stored model record; official gauges and reservoir readings are reported elsewhere and are not blended into this verdict. Open the source registry

Continental point and river scoring

A watch point's latest GloFAS discharge is located on its stored quantile grid for the same seasonal pool. Each river then uses its outlet point when scored, or the mean of its scored points when the outlet is unavailable.

Formula

point p = linear position of Q between stored percentile-grid values; river p = scored outlet p, else mean(scored point p)

Scored points: 158 / 158
Scored rivers: 101 / 101
Rivers below p25: 26
Median river: p48

Published result26% of scored rivers are running below their normal range

Data & provenanceGloFAS v4 daily river discharge via Open-Meteo; the percentile grid is built here from complete stored years. Open the flood API methodology

LimitAt least five complete years and enough observations in the seasonal pools are required. Unscored, stale and suspect points stay out of every denominator rather than being treated as normal.
