ABSTRACT. – The influence of atmospheric circulation, shape and pozition of the hydrographical basin on the amplitude and effects of the August 2005 flood in Ozana and Cracău basins. This paper examines the extent to which the shape of the Cracău and Ozana’s watersheds (tributaries of Bistrita and Moldova), and their position in relation to Stânişoarei Mountains chain influenced the amplitude and effects of the flood event that took place in August 2005. Another important aspect was the influence and particularities of the atmospheric circulation on the rainfall quantities in the two basins, in the 17th to 20th of August period. Moreover, this study takes into consideration the characteristics of the flood-related elements and it also quantifies the damages produced by the flood itself.

Key words: : basin shape and position, flood, atmospheric circulation, Ozana, Cracău, August 2005
