Rijkswaterstaat has finished a major sand replenishment project on the Dutch island of Ameland. In December 2025, the state agency, with contractor Boskalis, added more than five million cubic metres of sand from the North Sea to the island’s west and east coasts. At Hollum on Ameland‑West, about 2.5 million m³ was deposited directly on the beach to counter strong wind, wave and tidal erosion that removes sand from the area. On Ameland‑East, 3 million m³ of sand was placed on the seabed, allowing natural currents to transport it to the shoreline over time. The sand comes from offshore dredging sites at least 10 km from the coast. Before and after the dredging, scientists study the effects on local habitats to inform future projects.
