The Netherlands is adopting diverse strategies to manage river systems and combat the impacts of climate change. Initial efforts focus on implementing river biobarriers, which utilize hydraulic engineering combined with natural materials like wood and riparian vegetation to stabilize riverbanks and mitigate erosion. As climate projections suggest extreme fluctuations in water levels by 2100, the national approach is shifting toward giving rivers more space to behave naturally. This includes moving away from traditional containment methods in favor of landscape designs guided by soil and water principles. Additionally, researchers are investigating large-scale floating construction as a potential solution to address both the national housing shortage and the need for increased water storage and retention. Recent developments show an advancement in major hydraulic engineering projects to strengthen coastal defenses. Under the national Hoogwaterbeschermingsprogramma, work has commenced on the IJsselmeerdijk, where a consortium including Boskalis Nederland and Van Oord is placing sand in Lake IJsselmeer to create a foundation for a new foreshore and ecological zone. This aims to reduce wave impact on the 17.6-kilometre dike while supporting shallow-water and reed areas. Furthermore, the reinforcement of the Afsluitdijk has reached a milestone. The Levvel consortium, including Van Oord, BAM, and Rebel, has strengthened the 32-kilometre dike, increasing water discharge capacity from Lake IJsselmeer to the Wadden Sea by 45%. These upgrades include the commissioning of a new pumping station and discharge sluices at Den Oever, alongside new storm surge barriers and a fish migration river to facilitate movement between the lake and the sea.
