Exam 11: Running Water

The lower limit to which the stream can erode is its ____________________.

Mass wasting can be an important source of sediment carried in a stream.

How is the discharge of a stream calculated?

What is the infiltration capacity of a surface? On what factors does the infiltration capacity of a surface depend?

Particles move along a streambed by:

What powers the hydrologic cycle?

What is a 20-year flood?

A fan-shaped deposit of alluvium that forms adjacent to highlands in arid or semiarid climates is called a(n)____________________.

The total surface region that provides runoff to a stream system is known as a(n)____________________.

What happens when a stream overflows its banks?

What is the gradient of a stream?

Meandering streams have semi-circular cross-sections along most of their length.

A trellis drainage is a tree branchlike pattern of streams.

How often will a flood of a 20-year magnitude occur?

Braided streams have an intricate network of dividing and rejoining channels.

The outer bank of a meander in a meandering stream is called the ____________________,where (erosion/deposition)____________________ takes place.The deposit on the opposite side of the channel is called the ____________________,which is where (erosion/deposition)____________________ occurs.

The ideal graded stream has a balance among what five factors?

A stream's velocity varies only along its length.

How is the gradient of a stream calculated?

When infiltration capacity is exceeded and water begins to move rapidly downslope,a continuous film of water known as ____________________ flow develops.This type of flow can cause ____________________.
