ABSTRACT. - The assessment of floods within Coşuştea river basin, Romania (2000 - 2012). A statistical and conditional approach. The research aims to analyze the floods that occurred between 2000 and 2012 in the Coșuștea river basin, Romania. The study area has 449 km2 and it is extended over the north-western part of Getic Piedmont (lower sector), as well as on Mehedinti Plateau and Mountains, in its upper sector. To achieve the objectives, hydrological data from two hydrometric stations, Corcova (downstream, located in the piedmont area) and Șișești (upstream to the outlet of karstic upper section) were used, in order to identify trends, employing statistical methods and graphical representations. We also verified the existence of extraordinary levels, respectively conditions responsible for the differences in the maximum flows, their frequency and duration in the two measured sections of the river basin. Thus, the results include: the statistical treatment of hydrologic data on floods between 2000 and 2012 and contributing factors that may result in different values of flood elements at the two hydrometric stations.
