The quality and quantity of delta lakes- sediment depend on fluvial input and in-situ bio-geo-chemical processes. The present study investigates the quality of lacustrine sediments collected from two lakes - Tataru and Merhei, situated in different hydrodynamic environments within the Danube Delta, Romania, but both connected to fluvial input of water and sediment of the Danube. The following physical and chemical analyses have been carried out on several lake-bottom sediment samples: the main lithological compone...

The coastal area is the field of continuous interaction of marine hydrodynamic factors with those that act on the land. Since the prehistory, human communities have settled in this area, having access to both marine and land resources, drinking water being the most important. The Black Sea level is the drainage base level to which the surface waters of its hydrographic basin flow, but it also influences the groundwater dynamics. Southern Dobrogea is a typical geologic platform unit, divided in several tectonic blo...

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...

The UNESCO Convention on the Protection of the Underwater Cultural Heritage, adopted on 2 November 2001 is an international treaty aims to saving the underwater cultural heritage. Romania have joined the UNESCO Convention on the protection of the underwater cultural heritage in July 2007. The Western Black Sea shelf has been defined entirely as an archaeological site. Based on complex geological, sedimentological, stratigraphic studies and determinations of absolute age [2, 6] it was argued the existence of a cycl...
