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.

The Ropa, headwaters on the left. Side rivers drop in from above with the flow they deliver, each arrow landing on the water where it joins; reservoirs and their latest operator readings sit on the way down.

None of the 4 gauges on this stem carries an operator threshold or a stored seasonal reference, so flow is shown but not judged.

Main-stem gaugessource to outlet · select one for its sensor detail

Reference gauge: Topoliny1.14 m³/s · the furthest-downstream main-stem gauge currently reporting flow, so it captures the largest accumulated upstream reach.

Published station elevations come from the named provider. River power is gravitational power carried by the flow (ρ·g·Q·Δh), not metered generation - it is a floor rather than a total, because a reach whose downstream gauge reports no discharge contributes nothing. The navigability line is an indicative planning threshold, not an official fairway forecast. Side-river positions are approximated to the nearest main-stem gauge. A reservoir is drawn at its operator's own chainage where it stands on this river, and at the confluence where it stands on a side river of it - never at a kilometre borrowed from another river's scale.
