This article presents the results of studies of the hydrodynamical and sedimentological conditions of the Sulina Channel, the middle distributary of the Danube within its delta. One field campaign (at low waters) in September 2019 was conducted to analyse the geometry, the sediment composition and hydraulic conditions of the channel. During the field campaign, the measured water mean velocity was from v = 0.01?0.54 m.s-1 for a water discharge (measured upstream, at the bifurcation, knot Ceatal St. George) of 698 m...

In the Danube delta, on the Sulina Channel, the morphology and bedforms characteristics have been investigated. 3D bathymetry, flow velocity, and bed sediments data have been acquired, in order to investigate the dynamic of the bedforms, the distribution of the water, and their influence against the river bed. A single observation (in May 2019) was made regarding the geometry, sediment composition and hydraulic conditions under which the dunes grew and decomposed. The investigation focuses here mostly on the geome...
