Exam 16: Fluvial Systems and Landforms

When the water level in a lake or pond reaches a sufficient depth,it may spill over at a low spot on the landscape.This is called

The most common type of drainage pattern is the trellis pattern.

Ranking streams based on their size is called

The amount of discharge at any given place and time that is solely the product of groundwater seepage is called

The divide that separates the Mississippi watershed draining to the Gulf of Mexico from streams that deliver runoff to the Pacific Ocean is called the _________ Divide.

An artificial levee is an engineered structure along a river that raises the height of the riverbank and limits flood discharge.

List and describe the four types of drainage patterns associated with fluvial systems.

The level at which stream discharge can begin to spill out of the channel into the surrounding area is termed

Waterfalls are a result of the presence of a knickpoint.

The area between gullies and streams called the __________

__________ floodplains are regions near a river that is low and frequently flooded.

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

A(n)_______________ occurs when a portion of an abandoned stream channel is cut off from the rest of the stream by the meandering process and is filled with stagnant water.

Urbanization has caused rivers that have been modified through engineering to be flashy during precipitation events.

A knickpoint is a place where the stream gradient is significantly steeper than other locations within the stream.

________ is a term that describes the joining of two streams together.

This is the lowest level at which a stream can no longer lower its bed because it flows into the ocean,lake,or another stream.

Base level is a major control on a stream's behavior.

In a radial drainage pattern,streams radiate outward from a central point.

A river or small stream that curves back and forth across its valley is called a(n)
