These features directly provide habitat for such species. Furthermore, woody debris flow deflectors improve river morphology, creating differential areas of fast and slow flowing water. Energetic, faster flowing water improves sediment transfer, helping to keep gravels clean. It is also important for the formation of features such as riffles and pools as well as meanders. Slower flowing water provides a refuge for fish and invertebrates from high flows, and allows silt to settle out, eventually forming berms which will improve diversity of flow and plant communities. 22484 Complete Installing woody debris flow deflectors to improve habitat and morphology of Nobles Green Ditch. Nobles Green Ditch has historically ben heavily modified to improve flood protection and land drainage. It is failing to meet its WFD objectives for invertebrates. The mitigation measures assessment for the river revealed that measures were needed to improve in-channel morphological diversity. This project aims to address these issues.
