Stream restoration approaches can be divided into two broad categories: form-based restoration, which relies on physical interventions in a stream to improve its conditions; and process-based restoration, which advocates the restoration of hydrological and geomorphological processes (such as sediment transport or connectivity between the ...
Floodplain restoration is the process of fully or partially restoring a river's floodplain to its original conditions before having been affected by the construction of levees (dikes) and the draining of wetlands and marshes.
This can be accomplished by restoring flow to historic channels, or through the creation of new channels. In order for restoration to be successful, particularly for the creation of entirely new channels, restoration plans must take into account the geomorphic potential of the individual stream and tailor restoration methods accordingly.

A revetment in stream restoration, river engineering or coastal engineering is a facing of impact-resistant material (such as stone, concrete, sandbags, or wooden piles) applied to a bank or wall in order to absorb the energy of incoming water and protect it from erosion. River or coastal revetments are usually built to preserve the existing ...
After: East Credit Tributary stream restoration. Credit Valley Conservation (CVC) worked with a private landowner to daylight 500 m of coldwater stream on their Caledon family farm. [31] The project emerged from a decision to replace a failing tile drain on the farm property with a stream.
Channel incision is very common when head cuts are involved in stream morphology. In terms of stream restoration, head cuts are one of the most difficult challenges. Installing check dams or elevating the stream by filling the gully are common ways to mitigate up stream migration of the knickpoint. Another common way to control the knickpoint ...

Downcutting, also called erosional downcutting, downward erosion or vertical erosion, is a geological process by hydraulic action that deepens the channel of a stream or valley by removing material from the stream's bed or the valley's floor. The speed of downcutting depends on the stream's base level, the lowest point to which the stream can ...
