1.
Abrasion: The wearing away of rock by a grinding action.
2.
Base level: Lowest elevation to which the stream can erode downward, for many streams, the water surface level of the body of water into which they flow
3.
Bed load: Sediment moved along the bottom of a stream by moving water.
4.
Braided streams: An interwoven stream channel caused by accumulated sediments choking off the channel and the stream splitting into several smaller streams. Occurs when the load supplied to a stream exceeds capacity
5.
Breaking and lifting: Flowing water can break chucks of solid rock off the channel floor or wall. Violante form of scouring.
6.
Capacity of a stream: How much a stream can move.
7.
Competency of a stream: How big the size sediment a stream can move.
8.
Delta: Sediment deposited where a river flows into an ocean.
9.
Dendritic drainage pattern: a branching tree-like pattern of streams.
10.
Dissolution: the breaking up or dissolving of something into parts; disintegration.
11.
Dissolved load: Material transported by a stream that consists of ions or atoms.
12.
Distributary: a river or creek which flows out of a larger river
13.
Downcutting: Process of deepening a valley by erosion of the stream bed.
14.
Drainage divide: Boundary separating basins, such as a ridge.
15.
Ephemeral stream: stream that is created as a result of increased rain, isn't permanent.
16.
Headward erosion: The process through which land is worn away at the head of streams or gullies
17.
meanders: A winding, looping curve in the course of a river.
18.
Oxbow lake: A meander that has been cut off from the river
19.
Radial drainage pattern: Water flowing over a volcano, water drains in all directions from a central point.
20.
Rectangular drainage pattern: Network of interconnected rectangles and squares; develops over fractured/faulted rock
21.
Scouring: Process which results from the movement of a large bedload of sediment along the bottom of a stream
22.
Sheet wash: This is when a thin layer of water spreads over the land. Ditches are made by water constantly flowing over same spot
23.
Suspended load: The load contains small rocks and soil in suspension, which can make the river look muddy.
24.
Tributaries: Rivers and streams that flow into a larger river.
25.
V-shaped valley: Valleys eroded due to fast flowing water often found in upland areas
