 The Danube Delta lies at the crossing of the parallel 45° northern latitude with the meridian 29° eastern longitude. Area: 4.152 sq. Km, including 3.446 sq. km Romanian territory. The zone is relatively flat, with an inclination of 0,0060/00, permanently or temporarily covered by water (70- 80%). It looks like an equilateral triangle with some 80 km long side. With a discharge of 5.000-9.000 cubic m /sec., it carries annually 50 de millions tons of alluvia on the average (about 8 times more than the Tiber, 20 times more than the Rhine). The water temperature (13:00 hours): June 20° July, August 22°, September 18°. The main water courses are the 3 arms through which the Danube flows into the sea :           CHILIA - the northernmost and most active arm, with two groups of branches and a micro-delta of its own. Length: 105 km up to Periprava; maximum width: 1.000 m; maximum depth: 39 m. It carries around 60% of all river water; sinuousness coefficient: 1,56. Local shipping.                                                    SULINA - the shortest, straightest and most developed arm. Length: 64 km; maximum width: 250 m; maximum depth: 18 m. It carries about 22% of the river water; sinuousness coefficient: 1,03. River-maritime traffic channel (7.000 ton ships may sail where the arm is at least 7.32 m deep).                                   SFANTU GHEORGHE - the oldest arm through which the Danube flows into the sea. Length: 64 km; maximum width: 550 m; maximum depth: 26 m. It carries about 22% of the river water; sinuousness coefficient: 1,60. Local shipping.
