river restoration
Healing damaged waterways
River restoration is the practice of returning a river or stream to a more natural state after human modification has degraded it.
This may involve removing dams, reconnecting floodplains, reintroducing native vegetation, or undoing channelization.
The goal is typically to improve water quality, restore fish habitat, and revive ecological function: The salmon returned after the river restoration project removed the concrete weirs.
