17th EUROPEAN SEMINAR ON GEOGRAPHY OF WATER Working group: Floodingandfloodwatermitigation • Event Description • Conditions in most natural areas: • Flood lasts as long as runoff in river is increased • Conditions in most areas with flood protection (burst of embankments): • Flood lasts longer than runoff in river is increased(delayed backflow)
17th EUROPEAN SEMINAR ON GEOGRAPHY OF WATER Working group: Floodingandfloodwatermitigation • Conditions in Po-Delta: • Rivers are supra-elevated • Area lies below the sea-level • Water can not discharge to the sea • True for: • Precipitation • Increased runoff in river (branches of Po) • Burst of embankments Data: S. Piovan Sea level

17th EUROPEAN SEMINAR ON GEOGRAPHY OF WATER Working group: Floodingandfloodwatermitigation Po delta: Lack of management on a river basin level Poor communication and coordination between water management institutions Main problems of flood risk management Mattia Amadio Expensive flood protection (pumping stations, maintenance of embankments) Bad condition of ditches – private owners, no regulations, neglected www.dailymail.co.uk www.hullcc.gov.uk Warning system – not working effectively Low level of public awareness about flood risk • Padova: • Canal network - bad condition of the canals (vegetation, age)regulation of discharge sluices PankaBabukova

Awareness of territorial peculiarities as a pre-condition for the creation of a culture of risk “Natural hazard” or “territorial risk” ? 17th EUROPEAN SEMINAR ON GEOGRAPHY OF WATER Working group: Floodingandfloodwatermitigation Po Delta is a complex territory, resulting from the interaction of human societies and a changing environment. Technical representations of natural hazard, based on calculations (modeling) of flood level, cannot completely explain a complex risky territorial context: vulnerability is increased by human behavior, linked to cultural, social and historical factors Trust in human ability to control and “organize” nature Reclaimed lands
