Across
- 4. The depositional zone near a stream which receives flood water and deposits during streamflows that exceed the bankfull discharge
- 6. Two words. A channel-spanning pool habitat in which the scour element maintaining the depth of the pool is a channel-wide obstruction such as a bedrock falls or a debris jam over which streamflow plunges.
- 11. A reach that transports surface water year-round.
- 12. A narrow, confined channel through which water flows rapidly.
- 13. Two words. A habitat characterized by the presence of at least three channels running roughly parallel to each other and appearing distinct at flows less than bankfull.
- 15. Two words. A lateral (i.e., secondary) channel with an axis of flow roughly parallel to the mainstem channel.
- 16. A relatively homogenous section of stream having a repetitious sequence of habitat types and relatively uniform physical attributes such as channel slope, habitat width, habitat depth, streambed substrate, and degree of interaction with its floodplain.
- 18. Two words. A portion of the stream that usually has reduced surface turbulence and has an average depth greater than riffles when viewed during low flow conditions.
- 19. A secondary channel system that occupies a distinct drainage basin and has a unique headwater origin.
- 20. A human-made structure intended to impound streamflow
- 21. Two words. The vertical distance a fish would have to jump to pass into a culvert outlet from the downstream habitat.
- 22. The portion of the valley floor that is prone to relatively frequent flood events of 50 years or less.
- 23. Three words. The point along the downstream end of a pool where the water surface slope breaks into the downstream habitat.
Down
- 1. Land characterized by soils that are water-saturated at least part of the year. This wetland lacks a well-defined bankfull channel.
- 2. A pipe made of metal, concrete, or other material that transports water and sediment beneath a road.
- 3. Two words. A portion of the stream with increased water velocity.
- 5. A reach that transports surface water only during storm events.
- 7. Two words. This is the depth to which your stream survey partner sinks after filling up their waders.
- 8. The longitudinal (upstream to downstream) line of maximum depth within a stream channel.
- 9. An essentially vertical drop in the channel bed.
- 10. The flowing together of two or more streams.
- 14. A term used to describe streamflow, under the current climatic and hydrologic regime, which occurs on average once every 1.5 years.
- 16. Three words. Maximum pool depth minus maximum pool tail crest depth.
- 17. Two words. A habitat characterized by the lack of flowing water during a low flow (level II) survey.
