is a body of flowing water regradless of size

are large streams

is where water flows downhill under the force of gavity

the steepness of the vertical drop in the steam of channel (ft/mile)

the cross sectional are of flow - (width x depth) ft^2

the geometry of the path the steam follows is it straight of curved

a measure of the irregularity of the steams bottom ( manning’s roughness coefficient

the instantaneous volume of water per unit time passing a point in space in the steam ( ft^3/s)

is the geographic area that contributes water to a steam. it is defined by topography the surface water divide. it is importment to know the drainage basin for a steam

a graph that shows stream discharge over time.

a measure of the path taken by the stream channel

the distance measured along the steam channel betweentwo points divide by the straight line distance the same two points.

low gradient streams flow across the land in a series of curves, twist and turns. example lake oxbow

as the water flows into a meander, the force of the mvoing is directed to the outside bank which is recoded and sediment tends to deposit along the inside bank forming a struture

streams that cannot carry all he sediment dumped into them form braided channels. channels are choked with sediment and the water a new channel. this repeated process can form complex multiple channels that dead end and go nowhere

streams deposit thier sediment load when they no longer enough energy to carry the sediment. that usually happens when the velocity of the water decreases. Velocity will decrease if the channel area increases of the gradient becomes flatter or the discharge decreases.
