Influence of Channel‐Spanning Engineered Logjam Structures on Channel Hydrodynamics

Water Resources Research, 2022
AbstractNature‐based solutions to flood risk management, such as engineered logjams (ELJs), contribute to the reintroduction of wood in rivers. As part of stream restoration, and utilized in tributaries, ELJs increase upstream water levels, causing the flow to spill onto surrounding floodplains, resulting in the desynchronization of peak flows in a ...
