Restored Flooding for Living Deltas

Netherlands – de-poldering the Noordwaard


In 2015 the Noordwaard de-poldering project was completed. By means of lowering embankments, formerly protecting an agricultural area from high water levels in the Merwede river, controlled flooding can occur in the flow-through area in times of peak river discharges. Water is channelled towards the Biesbosch freshwater wetlands. As to date (2021) this has not taken place yet, but the main projects was supported by a number of smaller measures to restore tidal dynamics along the polder’s outer borders. These interventions have stimulated land-water interactions and ecological diversity in the area.
