  Classic Stream Problems; New Stream Solutions
Stream bank erosion problems are often caused as water is directed in to the bank by debris lodged in the channel.
Bank protection measures such as riprapping with large rocks on eroding area, or anchoring trees along stream banks can minimize the problem.
Stream straightening is a practice that was used frequently in the past, but less frequently today.

 Stream bed - Wikipedia, the free encyclopedia
The bed of this stream is made up of rocks, some very rounded (having had a longer life in the stream) and some not.
A stream bed is the channel bottom of a stream or river or creek; the physical confine of the normal water flow.
With small streams in mesophytic regions, the nature of the stream bed is strongly responsive to conditions of precipitation runoff.

 Stream Bank Enhancement
Tree revetment is a technique of laying trees along a stream side in a manner that reduces the erosive effects of the stream, protects the stream bank, and provides instant habitat for small fish.
To prevent the river from going behind and undercutting the revetments, large rocks (rip rap) were placed along the groomed stream bank both at the upstream and downstream ends of the structures.
Analogous to banking a billiard ball, the energy of the river simply bounced off the rip-rapped corner and caused an increased level of erosion at the next weakest spot, the next downstream corner; the neighbor's place.

 More Valley and Stream Erosion
The stream valleys of the headwaters of Bryant and her tributaries are considered youthful.
The headwater valleys have a relatively steep gradient and a cross-sectional profile that is "V" shaped with the stream occupying the bottom of the "V".
The flat bottom of the mature valley is called a floodplain because it is usually underwater during the largest floods and owes its existence to the deposition of sediments carried down from higher elevations during floods and deposited as gravel, sand and silt beds as the floods subside.

The bank of the stream is quite steep with a rise of about one foot for every three horizontal feet.
Evidence of erosion prevention is apparent along the banks of Willoway Brook as large stones called “shot rock” have been installed along the southern half of the stream bank.
In creating the meander, the slope of the stream bank would be greatly reduced to maintain a narrow stream when water flow is low, but a larger capacity when water flow is very high.

 A PILOT STUDY ON NEEDLE ICE INDUCED STREAM-BANK EROSION IN THE MASHAI VALLEY, LESOTHO HIGHLANDS
Stream or river bank erosion exerts an important control on the channel morphology and hydrology within an area (Church and Slaymaker, 1989; Lawler, 1993).
Although the soils dessicate during the long dry season, there is sufficient soil moisture and recurrent freezing along the stream banks to permit constant soil disturbance by needle ice from April through to early October.
Bank debris were collected from three troughs during the winter (May to August) of 1993, and from one trough for the spring (August to October) of 1993.

 Stream Processes
Since stream velocity is lowest (approaching zero) along the stream bed and increases toward the surface, the greater the rate of change of velocity near the stream bed the greater the shear stress applied to sedimentary particles lying on the stream bed.
Streams flowing between banks rich in clay and silt are deeper and narrower while streams flowing between banks poor in clay and silt are broad and shallow.
Streams that formerly fed as tributaries into the river may be cut off from the river by the broad levees.

 Ohio Stream Management Guide No. 14 Live Fascines
The bank needs to be composed of a material that can easily be trenched and that can hold moisture to support growing vegetation; the presence and predominance of fine soil particles and organic matter will meet this requirement while banks composed of sand or gravel will not.
In addition to installing the fascines, the toe of the bank slope may need to be stabilized through the use of another practice such as a revetment made from evergreen or deciduous trees (see Guide 12 Evergreen Revetments).
The live fascine bank stabilization project must be anchored to non-eroding portions of the stream- bank; if it is not, the bank will erode behind the fascine rendering it useless.

 RIPARIAN LAND USES AND PRECIPITATION INFLUENCES ON STREAM BANK EROSION IN CENTRAL IOWA1 Journal of the American Water ...   (Site not responding. Last check: 2007-10-09)
Human alterations to the Iowa landscape, such as elimination of native vegetation for row crop agriculture and grazing, channelization of streams, and tile and ditch drainage, have led to deeply incised channels with accelerated streambank erosion.
Significant seasonal and yearly differences in magnitude of bank erosion and total soil loss were partially attributed to differences in precipitation and associated discharges.
Bank erosion is a natural function of streams and cannot be eliminated entirely (Henderson, 1986).

 Ohio Stream Management Guide No. 11 Tree Kickers
One or more logs are anchored to the streambank on an outside curve and placed at an angle to "kick" stream flow away from the bank and toward the middle of the stream.
However, banks which lack vegetation and root structure are vulnerable to undercutting, so a kicker might be needed in addition to the new vegetation.
If this is a concern, and the stream size and project design allows the kicker log diameter to be about 6 inches or less, you can try anchoring the top end of the kicker log into the stream bed or bank to prevent it from floating.
