| The aim of the project is to upgrade the current flood protection structures of a dry polder next to the village of Rösa up to HQ200 (the peak level at maximum discharge occurring once within a 200-year period) protection level. Main elements of the project consist of: about 7,5 km of restored dykes 5 m wide at the bottom and 3 m wide on the crest; new influx and discharge installations; and two flood protection walls 1 225 m and 310 m long. The current dykes ensure protection against HQ100 only, but due to unpredictable extreme weather events, floods exceeding this level are likely and could seriously damage settlements and industry located downstream of the current polder.
