Key recommendations for sediment management: a synthesis of river sediments and habitats

The research aims to improve our understanding of the interactions between sediments, habitats and management of the watercourse in the context of delivering flood risk management (FRM) that is both cost effective and provides significant environmental benefits.

The process of sediment erosion, transport and deposition is important in forming habitat diversity in rivers and thereby influencing biodiversity. Sediments are the building blocks of discrete habitats, such as bars, which, depending on their character, are subsequently colonized by different species. Such features can also change the flow depth and velocity. In general, however, the more natural and varied the channel character, the higher the ecological value.
