This paper is a sequence that is part of the extensive analysis of the Danube Delta genesis. Sacalin island is a territory formed in the Black Sea, a short distance from the Romanian coast, in the south of the Saint Gheorghe branch of the Danube Delta, the main source of transport for alluviums.
The history of this new territory is relatively recent. The first mention was in 1771. In 1856, Captain Thomas Spratt made a new map, in which the island of Sacalin appeared with two submerged nuclei. In 1924, Romanian researchers made new measurements and found that the length of the island reached 10 kilometers, because in 2015 the length would be 19 kilometers. The present study demonstrates the factors that influenced Sacalin's formation. Numerical analysis was performed using the Computational Fluid Dynamics (C.F.D.) module in SolidWorks. It has been modeled the 3D continental platform, the Saint Gheorghe branch and the earth nuclei in different phases of evolution. The main data analyzed were the speeds of the Danube River currents and the velocities of the sea currents in the river-sea incidence area. The results obtained in the form of speeds, current lines and pressures were interpreted by comparison with the dynamics of the real evolution of the new territory. The importance of this study is the forecast of the future evolution of Sacalin. The research in this paper estimates the period when alluvial deposits around this new territory will generate a new lagoon at the Black Sea. The conclusions presented here are also important from the perspective impact of the Danube Delta Biosphere Reserve company, which manages the UNESCO protected area. |
