When a stream is able to effectively carry its average sediment load it is called a _____ _______.

Question

it's two words and I have absolutely no idea...

Answer 1

Stable Stream (with effective discharge)

Answer 2

Stream channelization

The southeastern U.S. Coastal Plain contains high-density stream networks and the largest area of alluvial wetlands in North America. Among the most common flood-control methods in this region is stream channelization. Its purpose is to increase channel capacity and flow velocity so that water moves more efficiently downstream and thereby reduces flooding. Channelization typically includes deepening and widening the stream channel and shortening it by cutting off meanders. Landowners and those who cultivate in the adjacent floodplains are the primary beneficiaries. In addition to closely involved government agencies, such as the U.S. Army Corps of Engineers and the U.S. Soil Conservation Service, local landowners have been the strongest advocates for channelization.

Awareness of the physical and biological problems caused by channelization is growing. Environmental degradation of alluvial habitats has been given serious attention in channelization project planning in recent years. Less destructive channel modifications have been implemented, and some attempts have been made to restore riparian habitats affected by channelization. For example, the Kissimmee River in south Florida, which was channelized in the 1960s, is being restored by reintroducing river flow into remnant channels (Loftin, Toth, and Obeysekera 1990; Shen, Tabios, and Harder 1994). The primary justification is the reestablishment of natural hydrologic conditions and the consequent enhancement of the river's biological resources. A similar restoration project is in the early planning stages for the Obion-Forked Deer River system in western Tennessee, also channelized in the 1960s.
