Danube 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.

Danube · official main stem

The Danube on physical national-network gauges, ordered upstream to outlet on one shared profile axis. 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. DanubeHIS currently exchanges main-stem stations from Austria, Croatia, Hungary, Romania, Serbia and Slovakia; Germany combines PEGELONLINE with non-duplicate DanubeHIS stations. Bulgaria, Moldova and Ukraine currently publish no main-stem station in this exchange, so they remain named source gaps.

Unbenchmarked

None of the 106 gauges on this stem carries an operator threshold or a stored seasonal reference, so flow is shown but not judged.

Czechia · Danube basin via Morava0 CHMI gauges · 0 directly on Morava

The Danube does not cross Czechia. Czech water reaches it through the Morava system, so Czechia is shown as a basin connection rather than falsely counted as an eleventh main-stem country.

Gauge coordinates and current discharge come from the named national hydrometric networks. The shared distance axis projects those GPS stations onto the dashboard’s sparse upstream-to-outlet spine; this is a profile axis, not surveyed navigation kilometre. The bed is interpolated between the dashboard’s anchor cells, because the registers on this river publish no gauge datum to draw it from. Where one register republishes another’s station, the two rows are one gauge and only the fuller record is plotted. 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.
