Abstract: The most common natural hazards affecting the Bâsca River Catchment (extended over a surface of 785.1 sq. km in the Curvature Carpathians) are floods and flooding. The purpose of this paper is to investigate and analyze structural and non-structural measures for flood risk mitigating in this catchment. The study focuses on the main factors which generate and favour floods, as well as on flood characteristics (frequency, the largest floods and its consequences). The main methods are the statistical analyze hydrologic and climatic data, field observations, expeditionary mapping and spatial analyses using Geographic Information Systems (GIS). In order to analyse flood potential, there were processes processed maximum instantaneous monthly and annual discharges of the Bâsca River at the Bâsca Roziliei hydrometric station (1953-2007), Varlaam I (1956-2005), Comandău h.s. (1968-2005) and of the Bâsca Mică River at the Brebu h.s. (1959-1974) and Varlaam II h.s. (1973-2005). Considerations on structural and non-structural measures for protection against floods are presented in the last part of the paper. An inventory of structural works in the middle and lower part of the catchment (hydrotechnical and erosion control works) and their condition was made.
