## Why does gradient decrease downstream?

Gradient (the slope of the land) decreases as rivers flow because the river meanders across the land rather than erode into it and follow a straight path as it does in the source. This means it covers a decrease in height over a longer distance the further downstream you get.

## What drainage pattern is common in the Appalachian Valley and Ridge province?

Drainage patterns in the Valley and Ridge Province directly reflect the alternating bands of resistant and easily eroded rocks in the folded strata of the province. Major streams and their tributaries intersect at right angles to form a rectangular stream network called a trellis drainage pattern (fig. 77).

## What is the volume of water flowing past a certain point called?

stream flow or discharge is the volume of water that moves over a designated point over a fixed period of time. It is often expressed as cubic feet per second (ft^3/sec).

## What is the vertical drop of a stream channel over a certain distance?

Gradient is usually expressed as the amount of vertical drop of a stream over a certain distance.

## What are the different types of water flow?

Within a stream channel three types flow can be observed:
• Laminar flow â€“ water flow in the stream is not altered in its direction. Water flows as parallel molecular streams.
• Turbulent flow â€“ water flows as discrete eddies and vortices. Caused by channel topography and friction.
• Helical flow â€“ spiral flow in a stream.

## What is flow of water in a channel called?

Streamflow or channel runoff is the flow of water in streams rivers and other channels and is a major element of the water cycle. â€¦ The discharge of water flowing in a channel is measured using stream gauges or can be estimated by the Manning equation. The record of flow over time is called a hydrograph.

## What is the term for a volume of water that is moved by a stream during a given amount of time?

Discharge is the volume of water moving down a stream or river per unit of time commonly expressed in cubic feet per second or gallons per day.

## What is channel runoff?

The sum of all the water flowing over the drainage basinâ€™s surface is called runoff. It is made up of streamflow which is flow through permanent river channels and overland flow or surface runoff.

## What is the most common drainage pattern?

dendritic drainage pattern

A dendritic drainage pattern is the most common form and looks like the branching pattern of tree roots. It develops in regions underlain by homogeneous material. That is the subsurface geology has a similar resistance to weathering so there is no apparent control over the direction the tributaries take.

## What comprises the suspended loads of most rivers and streams?

The suspended load of a flow of fluid such as a river is the portion of its sediment uplifted by the fluidâ€™s flow in the process of sediment transportation. It is kept suspended by the fluidâ€™s turbulence. The suspended load generally consists of smaller particles like clay silt and fine sands.

## How does stream gradient change in the downstream direction?

As one moves along a stream in the downstream direction:
1. Discharge increases as noted above because water is added to the stream from tributary streams and groundwater.
2. As discharge increases the width depth and average velocity of the stream increase.
3. The gradient of the stream however will decrease.

## How does a river and its valley change with distance downstream?

As a river flows down steep slopes the water performs vertical erosion . This form of erosion cuts down towards the river bed and carves out steep-sided V-shaped valleys. â€¦ As the river moves from the source to the mouth â€“ both the depth of the river and the width of the river will both increase.

## What makes a river flow faster?

1. Generally a narrower more circular river channel allows faster flow of water. Broader flat channels tend to slow a river down. â€¦ Generally anything that increases the surface area of the channel against which the water flows will tend to slow the flow because of the increase in friction.

## Why does the velocity of a river decrease?

This is because a river tends to become deeper wider and have a higher discharge the further downstream it moves. â€¦ In addition in the upper course the wetted perimeter of the river is higher in proportion to the area of the river than it is downstream. This increases friction on the water and reduces its speed.

## How did the Valley and Ridge pattern of East Tennessee form?

The landscape formed on Paleozoic sedimentary rocks that range in age from Cambrian to Pennsylvanian around 540 to 290 million years before the present. The ridges are composed of Pennsylvanian sandstone belonging to the Pottsville Formation whereas the valleys cut through shale limestone and dolomite.

## How are the Appalachian Plateau and Blue Ridge regions similar?

The Valley and Ridge region is located in northwest Georgia east of the Appalachian Plateau. The region consists of several high narrow mountain ridges and the valleys between them. â€¦ The regionâ€™s climate is similar to the Blue Ridge region with slightly less rainfall.

## What is the Appalachian Plateau in Virginia?

The Appalachian Plateau is the western most region of Virginia. It is located in southwest Virginia east of Kentucky. The Appalachian Plateau Region is the smallest region in Virginia.

## What stream stage has waterfalls and rapids?

Youthful River

Youthful River: The earliest stage in the development of a landscape. During this stage streams are actively downcutting and flowing straight for long distances with frequent waterfalls and rapids.

## How do stalactites form quizlet?

When water flows down through the ground into a cave it dissolves a mineral called Calcite and it carries through the cracks in the ceiling. The dripping water leaves behind traces of calcite which slowly builds up on the ceiling until a stalactite takes shape hanging down like an icicle.

## What is the name for the sediment that rolls or jumps along the bottom of a stream?

gravel) transported on the bottom of the. stream bed by rolling and sliding. â€¢ Saltation. â€“ Sediment (typically sand) transported by intermittent jumps â€“ a transitional state between bedload and suspended load.

## What is the name for the vertical drop of a river over a distance?

The vertical drop of a stream channel over a certain distance is called. gradient. in a typical stream where the gradient is steep the discharge.

## What are the boundaries called that separate streams in adjacent drainage basins?

In topography a drainage divide water divide divide ridgeline watershed water parting or height of land is elevated terrain that separates neighboring drainage basins.

## What is the ultimate base level of a stream?

sea level

The ultimate base level is sea level â€“ streams will not erode their channels below their base level. Many temporary base levels can exist along a streamâ€™s path. Erection of a dam results in creation of a lake which serves as the temporary base level for the up stream part of the river.

## What are the two main types of water flow?

Static water which comes primarily from lakes and ponds is called lentic water. Flowing water which comes from streams and rivers is called lotic water.

## What are the 3 types of water movement?

The types are: 1. Saturated Flow 2. Unsaturated Flow 3. Water Vapor Movement.

## What is overland flow in the water cycle?

Overland flow is the movement of water over the land downslope toward a surface water body. Overland flow is a very important aspect of the water cycle and can be generated under two different physical mechanisms.

## What do we call the winding channel of a river?

Answer: A meander is one of a series of regular sinuous curves bends loops turns or windings in the channel of a river stream or other watercourse.

## What is flow of water?

Running water flows naturally in a direction according to gravity along the slope and makes its own way. This is called a flow of water. When many such flows of water come together a river is formed.

## What is Channel Flow in geography?

Channel flow â€“ the movement of water within the river channel. This is also called a riverâ€™s discharge. Groundwater flow â€“ the deeper movement of water through underlying permeable rock strata below the water table.
