Channelization includes those methods of engineering (resectioning, straightening, construction of levees, diversions, etc.) that modify existing river channels or create new channels, often changing the relationship between river channels and floodplains. The most common purposes of channelization are flood control, land drainage improvement, creation of new spaces for urbanization or agriculture, maintenance or improvement of navigation, and reduction of bank erosion. Channelization is carried out both on very large rivers and small streams; it is widespread in lowland rivers, but also many upland (mountain) rivers have experienced this type of human intervention.

Abstract
Channelization includes those methods of engineering (resectioning, straightening, construction of levees, diversions, etc.) that modify existing river channels or create new channels, often changing the relationship between river channels and floodplains. The most common purposes of channelization are flood control, land drainage improvement, creation of new spaces for urbanization or agriculture, maintenance or improvement of navigation, and reduction of bank erosion. Channelization is carried out both on very large rivers and small streams; it is widespread in lowland rivers, but also many upland (mountain) rivers have experienced this type of human intervention.
