discharge |
in a stream, the volume of water that flows past a given point in a unit of time Q=VxA discharge= stream width x depth x velocity |
|
|
gradient |
slope of a stream bed - steeper slope, faster gradient slope=rise over run (Y over X) |
|
|
longitudinal profile |
a line showing a stream's slope, drawn along the length of the stream, as if it were viewed from the side |
|
|
tributary |
small stream flowing into a large stream, adding water to the large stream |
|
|
base level |
a theoretical downward limit for the stream erosion of the Earth's surface |
|
|
alluvial fan |
where sediment discharge is displaced as a fan above the surface |
|
|
delta |
sediment is deposited at the mouth of a river and the sediment load that is dropped makes a fan below the water |
|
|
drainage basin |
total area drained by a stream and its tributaries |
|
|
