Abstract-The dynamics of a river channel targets the interdependency relations between water, relief and sediments, as well as their effects within the fluvial system. This paper presents the dynamics of some fluvial islands (islets) from the river channel of the Danube between Giurgiu-Russe and Călăraşi-Silistra localities, corresponding to a part of the lower sector of the Danube, which constitutes the border between Romania and Bulgaria. The islets are fixed sedimentary deposits, stabilized, with a vegetation cover depending on the soil formation degree. We use the term "ostrov", as specified on the cartographic materials published in Romanian
