  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 Processes
Stream velocity is the speed of the water in the stream.
Stream velocity is greatest in midstream near the surface and is slowest along the stream bed and banks due to friction.
The ideal graded profile of a stream is concave upward: steeper near the head or beginning and flatter near the bottom or mouth of the stream.

Stream channels transport sediments and water from headwaters to mouth, systematically depositing and eroding, abrading and breaking sediment particles during the transport process (Knighton 1982).
Stream channels and floodplains are built and maintained by erosion and deposition of sediments during high stream flows (Leopold 1994; Whiting 1998).
In streams, primary sources of this sediment are erosion of uplands, accelerated lateral erosion of streambanks, and downcutting of streambeds.

 What is a Stream?
Streams are like the capillaries and blood vessels that connect to the major arteries, the rivers.
The length of a stream may be only a few feet from where it emerges until it joins another stream, or it may traverse hundreds of miles, from the mountains to the sea.
Many factors shape the character of a stream as it progresses from its headwaters to its mouth: the slope and current, the amount of water being transported, its temperature and water chemistry.

 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.

 Glossary of Forest Related Terms
Bed Material -- The sediment mixture of which a streambed, lake, pond, reservoir, or estuary bottom is composed.
Stream Channel -- The bed where a natural stream of water runs or may run; the long narrow depression shaped by the concentrated flow of a stream and covered continuously or periodically by water.
Stream gradient -- A general slope or rate of change in vertical elevation per unit of horizontal distance of the water surface of a flowing stream.

 Stream Habitat Types
In smaller streams of forested landscape, good habitat is associated with riparian canopy of at least 80% and a high component of conifers.
In streams as large as the NF Big, maximum pool depths greater than 4 feet may be a better indicator habitat condition.
Streams are arrayed by size: MF Caspar through Johnson are 2nd order, NF Caspar through West Chamberlain are 3rd order, Caspar through Chamberlain are 4th order, and the NF Big is 5th order.

 Lecture: Stream fluvial processes, Dr. Rodrigue
Stream processes entail the erosion, transportation, and deposition of earth materials from the floor and bed of a stream's channel by channelized water.
Stream systems are highly dynamic, changing the balance of erosion, transportation, and deposition tasks constantly and rapidly, always trying to achieve a dynamic equilibrium among inputs into the stream and capacity to move them through.
A stream that, on average, balances its load with its capacity is said to be graded, and grade is the dynamic equilibrium towards which all streams adjust their activities and slope angles.

 10(y) Streamflow and Fluvial Processes
Streams are powerful erosive agents moving material from their bed and banks.
Stream discharge is at a maximum and sediment load is generally composed of finer materials.
Because of frictional drag, stream velocity is at a maximum at the center of the channel near the surface and a minimum near the bed and banks.

 Channel Processes
The velocity of a stream, as much as any single factor, is responsible for determining the size of particles a stream can transport, as well as the way in which it carries the particles, or load (Larson and Birkland, 1994).
When streams drop below 4% gradient and their channels are unconfined, the energy of the stream drops and sediment tends to remain in residence for longer periods.
When a stream bed fills in as a result of bedload exceeding capacity it is said to be aggraded.

 Classic Stream Problems; New Stream Solutions
Many stream problems are caused by sediment choking the stream channel or by runoff that's too excessive for the channel to carry.
Stream bank erosion problems are often caused as water is directed in to the bank by debris lodged in the channel.
Stream straightening is a practice that was used frequently in the past, but less frequently today.

 Kawa Stream Description
Stream flow emerging from the hau is directed around the houses on Kumakua Place between two parallel hollow-tile walls.
The upper cataract on Kawa Stream (central branch) is over-grown with grasses and impatiens.
Stream flow from below the cataract is steady but weak through a steep sided gulch covered in Java plum and numerous juvenile cinnamon trees (Cinnamomum sp.) on one side; and mostly banana (Musa x paradisiaca) behind houses and yards on the other.

 Untitled Document
Streams can be thought of as a sediment transport system that attempts to maintain an equilibrium, a balance between load and capacity.
Where bed load is much greater than suspended load, the channel form is often braided, with lots of small channels running down the coarse stream bed.
Since flood waters have high velocity in the stream channel itself, the capacity in the stream channel is increased, and the channel may be eroded during the flood (which, of course, will change channel shape and size).

 Stream Invertebrates   (Site not responding. Last check: 2007-09-10)
The mid-reaches of the stream are surrounded by grasses and shrubs, and the lower reaches of the stream are surrounded by a gallery forest.
Other factors that may affect the dispersion of stream invertebrates are patterns of stream flow and water temperature.
Floods also affect stream invertebrate populations because the fast moving water scours the stream bed.

Eroded stream bank is a symptom of a bad stream channel; non-equilibrium channel.
Gravel bed load - the natural load of gravel and sediment moving downstream such that equilibrium (steady-state) is reached between arrival of new gravel and sediment from upstream and displacement of existing gravel and sediment in the stream bed and gravel bars to points further downstream.
Bankfull mark is top of the highest depositional feature (gravel or sand, whatever the stream deposits on point bars) in the channel; however, some scattered perennial vegetation may exist between the water and the bankfull mark, i.e.
