Reconnecting floodplains to rivers will help reduce the risk of future flooding, say U.S. scientists. Writing in Science, the researchers say that risk of flooding is likely to increase in the future as a result of climate change and shifts in land use. Floodwalls, levees and other channel hardening exacerbate flooding. The authors’ note: “Control [...]

Riparian areas filter nutrients and improve water quality. In agricultural-use watersheds, nutrient filtering in riparian zones can help control agricultural nonpoint-source pollution. Sediment deposition is a natural process that takes place during periodic flooding. Accelerated upland erosion can increase sediment deposition in riparian and wetland areas because of downslope movement of dislodged soil material. Such [...]
