No stretch of land along the river is left open to the floods. The Danube has a rate of flow of 10,000 m 3 /s (350,000 cu ft/s) at its fastest, and 600 m 3 /s (21,000 cu ft/s) at its slowest, in the region of Budapest. The difference between water levels can be as high as 6 to 8 m (20 to 26 ft).
The Danube gets slightly more than 4% of its total volume from its Bulgarian tributaries. As it flows along the northern border, the Danube averages 1.6 to 2.4 km in width. The river's highest water levels usually occur during the May floods; it is frozen over an average of 40 days per year.
In Austria and Hungary, most water is drawn from ground and spring sources, and only in rare cases is water from the Danube used. Most states also find it too difficult to clean the water because of extensive pollution; only parts of Romania where the water is cleaner still obtain drinking water from the Danube on a regular basis.

For example, in Europe the limit of time below LNWL is 20 ice-free days per year (e. g., on Rhine) or, alternatively, corresponds to 5–6% of the ice-free period on European rivers (6% on Danube [3]). [5] The highest navigable water level (HNWL) is defined as a water level that is exceeded for only a few days a year (usually 1%).
Rivers with an average discharge of 5,000 m 3 /s or greater, as a fraction of the estimated global total.. This article lists rivers by their average discharge measured in descending order of their water flow rate.
Finally, between 1835 and 1841, Vienna's first area-wide water pipeline system was built: The Kaiser-Ferdinands-Wasserleitung, which brought 20,000 m³ of filtered Danube water into the city every day. The growth of the city soon overtaxed this system – only about four to five liters per day were possible for each inhabitant.
With the lagoons of Razim–Sinoe (1,015 km 2 or 392 sq mi with 865 km 2 or 334 sq mi water surface), located south of the main delta, the total area of the Danube Delta is 5,165 km 2 (1,994 sq mi). The Razim–Sinoe lagoon complex is geologically and ecologically related to the delta proper; the combined territory is listed as a World Heritage ...
MANAUS, Brazil (Reuters) -The river port in the Amazon rainforest's largest city of Manaus on Friday hit its lowest level since 1902, as a drought drains waterways and snarls transport of grain ...
