Exam 16: Fluvial Systems and Landforms

_______ are small drainage channels that are cut into hillslopes by running water:

From the diagram,if the peak discharge is 1500,what is the recurrence interval?

Movement of sediment through saltation dominates in streams with calm water.

_____________ is a stream that is capable of transporting the average sediment load provided to it over time.

__________ occurs most commonly in association with wet periods when soils are saturated and pore spaces can no longer absorb additional precipitation.

_________ are the most active zones of fluvial erosion due to gravity.

________ is a low,level plain that develops where a stream flows into a relatively still body of water so that its velocity decreases and alluvial deposition occurs.

A drainage system that is typically associated with parts of the Appalachian Mountains where there are ridges and valleys is

This type of sediment transport moves large particles such as sand and gravel by rolling,sliding,or bouncing them along the channel bed.

When water overbanks repeatedly in an area,that area is called a(n)

What does the v term in the stream discharge equation ()represent?

The most common type of drainage system is

Drainage density is a measure of stream channel length per unit area of drainage basin.

Hydrologists classified the 1993 Mississippi River flood as a 1000-year flood.

The topographic lowering of a stream channel through stream erosion is called

Which of the following are transport mechanisms of streams?

A(n)_____________ is an engineered structure along a river that effectively raises the height of the river bank and thus confines flood discharge.

An accumulation of sediment on the outside of a stream meander is called a point bar.

What does the Q term represent in the stream discharge equation ()?

Dissolved load consists of mineral ions carried in solution and are invisible during transport.
