which of the trends shown illustrates how the discharge varies along the course of a stream?

How do you calculate the discharge from a stream?

Stream discharge: volume of water flowing through some stretch of a stream during a period of time. Collecting measurements from the stream with a gauging station. measure cross-sections of the stream. Calculate it: Q= stream depth x stream width x stream velocity (Q=DWV )

Where does stream flow occur the fastest?

C. Stream flow is fastest in the center of the channel near the surface. D. Water from trunk streams flows into tributaries. Stream flow is fastest in the center of the channel near the surface https://sw5.wwnorton.com/problemsets/filemanager/userfiles/P.Jayaraman@spi-global.com/17.9b.jpg

What is the sediment load of a stream?

The amount of sediment carried by the stream, including material chemically dissolved in solution, is the sediment load. near the bottom of the stream upward-flowing eddies can overwhelm gravitational force and lift grains from the channel. Turbulence, in general increases the chance for grains to be picked up and can erode into channels

What is the velocity of the stream in this diagram?

The stream in this diagram flows at a velocity of 6 feet per second. Its discharge is ... illustrates that a stream's gradient is steeper near its headwaters than near its mouth.

Does vegetation increase or decrease slope stability?

The presence of vegetation can either increase or decrease the stability of a slope

Does the proposed road cut decrease slope stability?

The proposed road cut will decrease the slope stability

When is the lowest discharge in a stream?

the amount of precipitation, snowmelt, and influx from springs and groundwater varies. the lowest discharge in the winter when some streams and lakes are frozen and precipitation occurs as snow and as gentle winter rains. discharge is highest during spring when the snow and ice melt. Describe the typical profile of a stream.

What happens when a river or smaller stream enters an ocean or a lake?

Describe what happpens when a river or smaller stream enters an ocean or a lake. Several landscape building processes occur when a river or smaller stream enters the ocean or a lake. Large rivers like the Mississippi river pump freshwater far into the ocean and carry fine sediment out to sea.

Why is sediment deposited along mountain fronts in alluvial fans?

Because when a mountain stream reaches less confined space it has to spread out in a network of sediment filled braided streams. stream deposits sediment along its channel and over a broad floodplain.

Why do mountain streams have sediment?

Because when a mountain stream reaches less confined space it has to spread out in a network of sediment filled braided streams. stream deposits sediment along its channel and over a broad floodplain

What is the amount of sediment carried by the stream, including material chemically dissolved in solution, called?

The amount of sediment carried by the stream, including material chemically dissolved in solution, is the sediment load.

How do dams help the environment?

Dams provide hydroelectric power generate water storage or flood control, stopping streams normal flow and transport of sediment. Change in base level. stream to deposit sediment behind the dam. Dam releases relatively clear water that is starved of sediment and renewed capacity to erode.

What is the term for the material that is pushed, bounced, rolled, and slid along the?

material that is pushed, bounced, rolled, and slid along the bed of the stream is the bed load. if the amount of sediment exceeds the stream's capacity to carry it, the sediment is deposited

What is a stream?

a stream is any channelized body of running water.

What is the slowest moving part of a stream called?

B. The slowest-moving part of a stream is called the thalweg.

Which region will decrease downstream?

likely to decrease downstream in arid regions and increase downstream in temperate regions

What is a meander bend that gets cut off from the stream called?

B. A meander bend that gets cut off from the stream is called a point bar lake.

What is the slowest moving part of a stream called?

A. The slowest-moving part of a stream is called the thalweg.

Which is steeper, a stream's headwaters or its mouth?

Illustrates that a stream's gradient is steeper near its headwaters than near its mouth

What happens if a dam is constructed properly?

If a dam is constructed properly, it will not change the ecosystem of the area it's in. D. Use of the waters of major rivers, like the Colorado River, has not affected their size or discharge. Early civilizations of Egypt, India, and China were established in river valleys and on flood plains. ...

What is a stream that swings back and forth in snake-like curves called?

D. A stream that swings back and forth in snake-like curves is called a braided stream.

How does C. form?

C. form when water gently spills over a gradual ledge, hugging the rock wall.

What is a B stream?

B. is an interconnected group of streams that collects water over a large area.

Where is stream flow fastest?

Stream flow is fastest in the center of the channel near the surface

Where does 90% of water vapor enter the atmosphere?

D)high and the humidity is high. C. Nearly 90% of the water vapor that enters Earth's atmosphere comes from the evaporation of Earth's surface waters. Most of the remaining 10% is water vapor that enters the atmosphere.

What particles provide surfaces on which water vapor can condense?

D) Dust particles provide surfaces on which water vapor can condense.

What is the main source of dissolved salts in the sea?

A) Dust particles are the main source of dissolved salts in the sea.

Which air mass is warmer and more humid?

A)The mT air mass is warmer and more humid.

What happens to air in winter?
