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...

The coastal retreat in touristic areas concerns many sectors along the Romanian Black Sea shore; it usually requires programmes for beach nourishment, and consequently, large amounts of proper sand are necessary to be available for such activities. In order to minimize the effort for searching offshore sand, we conducted seismo-acoustics researches and some other archived data have been used during these researches, both for planning the sea works and during the integrated interpretation of the data. The results o...
