Question 8

Drainage Basin

Answer 8

-area that contributes surface water to a particular stream network

Divide

Answer 9

line that separates adjacent drainage basins

Question 10

watershed

Answer 10

• land area that contributes water to a particular stream system
• generally used to describe the catchment area for a small tributary stream

Question 14

Discharge

Answer 14

quantity of water flowing past a particular point , usually measured in cubic feet per second or cubic meters per second

Question 15

100 year flood

Answer 15

a higher than usual stream discharge that has a 1% percent probability of occurring in any given year.

Question 16

channel pattern

Answer 16

the shape of a flowing stream as viewed from above

the three most common types are straight, meandering, and braided

Question 17

channelization

Answer 17

engineering technique to straighten, widen, deepen, or otherwise modify a natural stream channel

Question 18

flash flood

Answer 18

overbank flow that results from a rapid increase in stream discharge; commonly occurs in the upper part of a drainage basin and small tributary downstream

Question 19

floodplain

Answer 19

flat topography adjacent to a stream produced by overbank flow
