Reconnection of oxbow lakes and similar features
Code:
N07
Sector:
Hydro Morphology
The complete description of the NWRM:
Summary:
An oxbow lake is an ancient meander that was cut off from the river, thus creating a small lake with a U form. Reconnecting it with the river consists in removing terrestrial lands between both water bodies, therefore favouring the overall functioning of the river by restoring lateral connectivity, diversifying flows and cleaning the river section of the present oxbow for a better water retention during floods.
