The polder will cover an area of 2630ha with a retention volume of about 185Mm³ in a flood event. The dike will have a length of 21.8km and be built as an earthfill dam with an embankment volume of about 7.4Mm³. Hydraulic structures such as gates, spillways, etc will be constructed in order to regulate the filling and emptying of the polder during a flood event.
A disastrous flood in 1997 on the River Odra in Poland killed 54 people and caused extensive damage to infrastructure. As a result a comprehensive program was developed, funded by the World Bank, to enhance flood protection and to protect more than 2.5 million people against flooding.
