Most of the coast of the Danube delta is severely eroding, although the northernmost distributary (the Chilia) which collects most of the water and sediment discharged by Danube can sustain a continuous progradation of its lobe. Longshore sediment drift patterns for the Romanian deltaic coast, based on a sand budget and predicted potential net sediment transport, indicate that shoreline behavior is mainly prescribed by energetic waves with an acute angle of attack. Shoreline behavior is negatively influenced by the natural and human-induced decrease of the Danubes sediment discharge, and by the jetties and dredging practice at Sulina mouth and Midia Harbor. The Sfantu Gheorghe deltaic lobe appears to be polygenetic with significant sediment sources which are both fluvial and marine, and with both cross-shore and longshore agents controlling the sediment redistribution.
