Lăpuş River is the most representative local watercourse in Transylvania, for the extreme hydrological events and negative effects induced in the territory. Its basin covers an area of about 1875 km². This study is focusing on the synthetic analysis of Lăpuş basin historical flood (March 3-6, 2001) with special regard on all phases of the risk generator event. Thus, we have evaluated the genesis flood conditions (thick layer of snow - 50 cm, liquid precipitations between 75 and 193 mm accumulated in three days, air positive temperatures, drainage and hydraulic favourable conditions). Also have been considered the characteristic elements of the flood (high flow period, double pulse flood wave, discharge flow and historical volume, the exceeding time intervals for the threshold defence levels monitored at gauging stations) and special effects in the territory (massive infrastructure damages, fortunately without casualties). At the end of the study was developed an integrated map that quantifies the effects of extreme flood and vulnerable areas associated with potential structural measures in order to mitigate future floods.
