Across:

2. A basin structure in which the streams converge toward the center.
3. A treelike, branching pattern that consists of a random merging of streams, with tributaries joining larger streams irregularly.
4. A former stream meander through which the stream no longer flows.
5. The side to side, valley-widening, erosional process active with meandering rivers.
6. Concept that a landscape/river that was formerly in equilibrium can be reenergized by regional uplift. Produces a river and landscape that experiences ____________.
11. Branching stream channels that cross a delta.
12. Any stream deposited sedimentary material.
13. The line of separation between runoff that descends into two different drainage basins.
14. _____ are defined as areas where the river's banks are built up above the level of the rest of the floodplain. Natural _____ are produced during periods of flood flow.
15. A stream that is at equilibrium with its load; the stream is just able to transport the load.
18. The higher land or ridge about the valley sides that separates adjacent valleys.
19. A cutoff meander that initially holds water.
20. The name of a stream that runs parallel to, and within the floodplain of, a larger river.
21. The _____ load consists of very fine particles of clay and silt that move in the water without ever touching the stream bed.
23. The ___ load consists of minerals, largely salts, that are carried invisibly in the water.
24. A depositional feature created when a stream carrying sediment comes out from a mountain canyon.
25. The size of the largest particle that can be transported by a stream.
27. An oxbow lake that has been at least partly filled with sediment and vegetation.
28. The _________ of a stream meander is the bank where erosion is concentrated.
29. The type of river/stream that consists of one main channel that loops from side to side.
31. A deposit of sediment, usually sand, that occurs along the inner edges of the meanders of channels.
32. Is the channel centerline where the water is moving the quickest and where the greatest erosion takes place.
33. A ______ is a landform created by running water eroding sharply into a hillside. They resemble large ditches or small valleys and often result from the merging of smaller channels called rills.

Down:

1. A stream that flows only for short periods over a year. Flow events are usually initiated by rainfall.
7. The _____ load consists of the larger fragments moving in a stream by saltation and traction.
8. A _______ is one in which the river is actively downcutting and is riddled with rapids, wateralls and riffles.
9. A stream that consists of multiple interwoven shallow channels separated by low bars or islands of sand, gravel, or other loose debris.
10. _____ is the lowest level to which a river can erode its channel.
16. Smaller side streams that join a river are ___________.
17. A flattish valley floor covered with stream deposited material and subject to river flooding periodically.
22. A sharp irregularity in a stream-channel profile - a drop off.
26. The maximum load that a stream can transport under given conditions.
30. A depositional landform at the mouth of a river produced by the sudden slowing down of the stream's velocity.
