A network of reinforced levees and designated floodplains (polders) that can be intentionally flooded to reduce pressure on urban infrastructure. Emergency Procedures
Constant tracking of water levels at gauges like Trestno (the key monitoring station for Wrocław).
To protect the city, Wrocław utilizes a complex hydraulic system called the (Wrocławski Węzeł Wodny). This system was significantly modernized following the 1997 floods and includes: A network of reinforced levees and designated floodplains
The city issues "warning levels" followed by "alarm levels" as water heights cross specific thresholds.
A massive wave arrived, but thanks to better coordination and sandbagging, the city remained largely dry despite levels reaching 650 cm . This system was significantly modernized following the 1997
Closing floodgates, securing drainage systems, and deploying mobile flood barriers in low-lying areas like Ostrów Tumski or the Zoo . Historical Context
A massive dry polder upstream designed to "shave" the peak of the flood wave before it reaches the city. Historical Context A massive dry polder upstream designed
A occurs when heavy or prolonged rainfall (often combined with snowmelt) in the upper reaches of the Odra and its tributaries (such as the Nysa Kłodzka) causes water levels to rise rapidly. As this volume of water moves downstream, it forms a "wave" that eventually reaches Wrocław. The Wrocław Water Node (WWN)
