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 ...
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 ...
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.
Daylighting is the opening up and restoration of a previously buried watercourse, ... Further priorities were protection for habitat, restoration of stream beds ...
Rocky stream in Italy Frozen stream in Enäjärvi, Pori, Finland Stream near Montriond in south-eastern France Aubach (Wiehl) in North Rhine-Westphalia, Germany. A stream is a continuous body of surface water [1] flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a ...
A large reason for stream restoration is to remove nitrogren and phosphorus pollution. Excess nitrogen and phosphorus from anthropogenic activities have partaken in stream and river quality concerns such as drinking water contamination, hypoxia, and algal blooms. [10] There are different approaches one may take to offset these effects.
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 ...
