Birds find shelter The Scheldt has one of the largest estuaries in the willow tidal forests and reed in Europe, a funnel-shaped river mouth beds in the marshes and food in where river water and seawater meet and the mud flats. where tides are distinctively clear. In the last few centuries, we have forced the Scheldt Spawning and breeding ground and its tributaries into a straightjacket by for fish. Fish find a quiet spot to impoldering areas and straightening the breed and their young can grow in rivers. This has resulted in less room for them a protected location. to overflow their banks, affecting the risk of flooding. This risk is also increasing as a Levee protection. The marshes result of climate change: sea levels are rising, reduce the strength of the river storms are increasingly intense and flooding water. The waves no longer batter more frequent. Other consequences are hot the river levees as hard, thereby summers and droughts. preventing erosion. Higher oxygen level. The water here is relatively shallow. This Together with these partners, we are creating ensures considerable contact a climate-resilient and future-proof Scheldt Valley: between the water and air, resulting in more oxygen in the Better water. Sunlight is also well able to Nature as an ally penetrate the water, enabling algae protection to create more oxygen. Flanders Hydraulics Research Tidal nature consists of low-lying mud flats against flooding and higher-lying marshes that flood either in full or in part during high tide. In the past Transfer and intake of nutrients Flanders has formulated the Sigma Plan to Mud flats few decades, a tremendous amount of tidal and source of silicon. create a climate buffer against rising sea and marshes filter out excess www.life-sparc.eu nature has disappeared, while wetlands are levels and extreme weather conditions. How? nitrogen from the water, while a necessary ally against the consequences By offering the Scheldt and its tributaries enriching it with silicon. This helps of climate change. A resilient river with a more space through flood control areas (to repair the food chain. sufficient amount of mud flats and marshes capture excess river water) and depoldering can protect the entire region from extreme (to slow down storm water).
