Directions of Polderization in the Middle Basin of the Odra River

As an effective way of flood prevention it is widely accepted to construct flood embankments. These structures are getting bigger as the river changes from meandring to successive development of floodplain and narrowing the embankment. Meanwhile, it is worth returning old solutions and reactivating old floodplain polders. There are currently three polders on the central Odra River: Kiełcz-Tarnów-Bycki – with a capacity of approximately 15 million m³, Połupin – with a capacity of 70 million m³ and Krzesin-Bytomiec – with a capacity of 20 million m³. Three further reservoirs are designed in: Urad – 30 million ha, Słubice Górzyca – 60 million ha and Ługi Górzyckie – 30 million ha. The authors propose additionally a reactivation of seven archival polders, with total capacity of approximately 4.9 million m³.
