Wind impact on the plume development and suspended matters transport according to optical scanners

摘要

It is studied the plume response, formed by the Danube River in the North-Western part of the Black Sea, to the wind forcing. Two cases are considered: the wind of the N-NE and S-SW directions. The plume evolution, alongshore flow formation and suspended matter transfer are analyzed on the base of satellite data at a wavelength of 551 nm for these two wind forcing scenarios. The coastal current dynamics and formation of Danube plume and salinity front are studied on the basis of 3D numerical model which was adapted to the conditions of the North-Western shelf. The obtained results from the satellite data analysis are compared with results of numerical simulation of plume formation under the action of wind in order to estimate the model sensitivity to variations of the wind direction and of the wind speed magnitude.
