The asymmetrical Suceava river basin, with a surface area of 2 612 km², is located in the north of Romania, but it also extends to the territory of Ukraine up to 47 o58 'N. This river basin comprises two large rescue units with distinct geographical characteristics (mountainous and plateau), separated by a transitional area represented by a Piemont area and a succession of depression. Flood analysis was carried out using data from 8 hydrological stations monitoring the flooding of the main river (3) and the largest tributaries of the river (5). After analysing the natural and human factors that caused the June – July 2010 floods, the space for the flood waves, the time and water parameters of the rivers monitored was determined and, at the end, it assessed the environment and the social and economic risks identified by the floods.
