Of the three arms of the Danube, the Kilia, the Sulina and the St George, the central or Sulina branch, owing to its greater depth of water over the bar, had from time immemorial been the principal waterway for sea-going vessels; its average depth throughout its course, which could not always be counted on, was 8 ft., but it contained numerous shoals where vessels had to lighten, so that cargo had often to be shifted several times in the voyage down the river. It also contained numerous bends and sharp curves, sources of the greatest difficulty to navigation.

The Hungarian government also, throughout the latter half of the 19th century, expended vast sums at Budapest for the improvement of navigation and the protection of the town from inundation, and in the regularization of the Danube down to Orsova.
In prehistoric times a great part of the plains of Hungary formed a large inland sea, which ultimately burst its bounds, whereupon the Danube forced its way through the Carpathians at the Kazan defile. Much of what then formed the bottom of this sea consisted until modern times of marshes and waste lands lying in the vicinity of its numerous rivers.

The principal navigation company on the upper Danube is the Société Impériale et Royale Autrichienne of Vienna, which started operations in 1830. This company also owns the Fünfkirchen mines, producing annually 500,000 tons of coal. The society transports goods and passengers between Galatz and Regensburg. A less important society is the Rumanian State Navigation Company, possessing a large flotilla of tugs and barges, which run to Budapest, where they have established a combined service with the South Danube German Company for the transport of goods from Pest to Regensburg.
