Channel modifications in Tennessee, particularly in the western part, have led to large-scale instabilities in the channelized rivers and may have contributed to several bridge failures. These modifications, together with land-use practices, led to downcutting, headward erosion, downstream aggradation, accelerated scour, and bank instabilities.

Results showed that channel evolution processes may be divided into four phases: I (–) rapid aggradation, II (–) channel widening and enlargement, III (–) main.
Streams are dynamic systems, so steady state does not exist for any appreciable period of time. Streams in dynamic equilibrium respond quickly to change, regaining a new equilibrium. These effects may be substantial: Increases in channel width caused by channelization-related erosion range as high as % to %. Channel modifications in – on the South Fork of the Forked Deer River in western Tennessee, for example, shortened channel lengths by 14% and increased streambed gradients by as much as %.

The site is located in the western part of the Piedmont physiographic province in the foothills of the Blue Ridge Mountains ().The bedrock is a Precambrian quartzofeldspathic biotite gneiss that weathers to form the residual Hayesville series soil (Rader and Evans, , Cited by: A careful study of the factors listed in Table 1 should present the reader with sufficient reason to suspect that most of these factors affect every stream in developed watersheds of the United States. Massive changes in vegetation, land use and weather patterns have led to increased downcutting of channels in coastal California, with the largest watersheds responding first, . Tennessee. and Ohio Rivers, reported that erosion silts had destroyed a large portion of the mussel population in various streams by directly smothering the animals in localities where a thick deposit of mud was formed, and by smothering young mussels even where the adults could maintain themselves.
