Multibeam Bathymetric Investigations of the Morphology and Associated Bedforms, Sulina Channel, Danube Delta

Research on the Sulina Channel of the Danube Delta reveals that dune bedforms, primarily composed of fine sand (D50 between 0.06 and 0.35 mm), follow a distinct geometric relationship where height (H) correlates with length (L) through the formula H = 0.093L^0.5268. The study, conducted using multibeam bathymetry, flow velocity measurements, suspended-load concentration data, and discharge records, identified shear stresses ranging from 2.86 to 8.62 N·m^-2 across the dune field formation. Water velocities during the February 2007 field campaign varied between 0.22–1.13 m·s^-1, providing insights into sediment dynamics and hydraulic conditions influencing dune growth and degeneration.
