First cycle of implementation – Flood Hazard and Risk Maps
Hazard refers to the possibility for floods to occur, while the Risk involves the estimated adverse impact on the population, property, environment, cultural and economic heritage. Both are represented by means of maps.
Hazard maps are prepared by using hydraulic modeling techniques and show the depth and extension of the water surface in the case of different flood scenarios, from extremely serious floods, with a low probability of occurrence, to low intensity floods, with higher probabilities of occurrence.
Based on hazard maps, risk maps are prepared, indicating the damages likely to be caused by different flood scenarios, as well as the prejudice to human life, property, environment, cultural and economic heritage.
