Quick Summary

The Sulina is a navigable channel of the Danube River in Romania. Near the city of Tulcea, the Danube branches into the Sulina and St. George tributaries before emptying into the Black Sea. The Sulina channel is navigable by seagoing vessels and has been straightened and dredged to maintain a navigable depth. This channel is one of the three main distributaries of the Danube delta, with the Chilia and Sfântu Gheorghe being the others. The Sulina channel carries about 16 percent of the Danube's total runoff.12
