What is a long profile River?
A long profile is usually concave and the slope becomes more gentle towards the mouth of the river. Long profiles usually have irregularities such as waterfalls or lakes. Rejuvenation also creates knick points (more on this later). The video below provides a simple reminder of the changes that occur along the long profile of a river.
What is a company profile and why is it important?
It informs potential customers, stakeholders and the general public about your products, services, and business as a whole. A company profile can be anything from a few sentences to an entire page on your website – most businesses have a long and short version – and is a good way to differentiate yourself from other businesses. Why Is It Important?
What should be included in a company profile?
Include plenty of relevant information at a glance. While the company profile might include a few paragraphs of narrative, you can also use bulleted lists to highlight products or services or key company information. Also, make sure to include a block with contact information and links to your website or social media profiles.
How do you write a company profile for a resume?

How would you describe a long profile of a river?
The long profile of a river shows changes in the height (altitude) of the course of a river from its source to its mouth. A long profile is usually concave and the slope becomes more gentle towards the mouth of the river. Long profiles usually have irregularities such as waterfalls or lakes.
Why is a long profile of a river important?
The long profile of a river is a way of displaying the channel slope (gradient) of a river along its entire length. Therefore, it shows how a river loses height with increasing distance towards the sea. A river tries to achieve a smooth curve to reach its base level at sea; this is called a graded long profile.
What is the difference between a long profile and a cross profile?
The average flow velocity of a river increases along its long profile. This makes sense; along the profile, more potential energy is converted to kinetic energy, increasing the velocity. This is only the average velocity however; a cross-section of a river shows that the velocity varies from one side to the other.
How do rivers change along the long profile?
Long profile A river changes with increasing distance downstream from its source towards its mouth. It moves through its upper course , to its mid-course and finally into its lower course .
What are the three parts to the long profile of a river?
The first part of the river profile is known as the Upper Course or Mountainous Course or youthful stage. Second part of river profile is known as Valley Stage or mature stage or Middle Course. Third part of river profile is known as Plain Stage or old age or Lower Course.
Is the long profile of a river concave?
Erosion in the upper valley is generally straight down into the bed, and vertical, helping to keep gradient steep. In the lower reaches erosion is lateral or side to side, reducing gradient and further enhancing the concave long profile. Base level is the lowest level to which erosion by running water can take place.
Where does the long profile start?
Long profile Upper course - this is where the river starts and is usually an upland area. The river's load is large in the upper course, as it hasn't been broken down by erosion yet. Lower course - - the final course of the river is where the land is a lot flatter.
How does long profile change downstream?
Long profiles 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. As the river flows towards the mouth, the gradient of the slope becomes less steep.
What does a cross profile look like?
River cross profiles show you a cross-section, taken sideways, of a river's channel and/or valley at certain points in the river's course. A channel cross-profile only includes the river whereas a valley cross-profile includes the channel, the valley floor and the sides of the valley.
What shape is the long profile diagram of a river?
The long profile is often portrayed as a smooth concave shape although in reality there are sometimes sharp drops in gradient due to differential geology or rejuvenation (how a river responds to changes in base level caused by sea level change).
Which part of the long profile has the deepest channel?
In hydrological and fluvial landforms, the thalweg is a line drawn to join the lowest points along the entire length of a stream bed or valley in its downward slope, defining its deepest channel. The thalweg thus marks the natural direction (the profile) of a watercourse.
Why does discharge change along the long profile of a river?
This is due to the height difference between its altitude and the base level. As a result of this potential energy and the need for the river to cut down and balance its energy the river vertically erodes in the upper course. In the middle and lower course the river has increased in discharge as well as suspended load.
What does a long profile show?
A long profile is a line representing the river from its source (where it starts) to its mouth (where it meets the sea). It shows how the river changes over its course.
What are the significance of profile in geography?
Profile or a section is a method which helps to visualize the relief feature for a larger area drawn along a selected base line.
What does a longitudinal profile of a stream show?
The longitudinal profile characterizes average stream slopes and depths of riffles, pools, runs, glides, rapids, and steps. The average water surface slope is required for delineating stream types and is used as a normalization parameter for developing ratios (Figure 12).
What is the long and cross profile of a river?
The cross profile of a river shows how the width and depth of the river valley and channel change as you travel downstream. Near the source of a river there is more vertical erosion as the river flows downhill, using its energy to overcome friction (A).
What is the long profile of a river?
The long profile of a river is a way of displaying the channel slope (gradient) of a river along its entire length. Therefore, it shows how a river loses height with increasing distance towards the sea. A river tries to achieve a smooth curve ...
Why do discharge and velocity increase downstream?
The volume of water passing a given point on the river is known as its discharge. Discharge is measured in cubic metres per second (cumecs). To calculate discharge use the formula:
How does the gradient of a river become more concave?
The gradient of the long profile becomes more concave as the vertical erosion reduces .
What happens to the gradient of a long profile as the vertical erosion reduces?
The gradient of the long profile becomes more concave as the vertical erosion reduces.
Why does the gradient change as a river flows downstream from its source?
As a river flows downstream from its source the profile changes due to the interaction of the process of erosion, transportation and deposition. The long profile of a river.
Why does velocity increase along the course of a river?
The reason for this is because velocity is affected by how much water is in contact with the bed and banks.
What is the lower course of a river?
The lower course is closest to the mouth of the river where the land is low-lying. Erosion is confined to lateral erosion at meanders. The gradient is almost flat due to the lack of vertical erosion.
