Why are headwaters important?
Headwaters supply food and critical nutrients: The headwaters are a critical food source for the entire river. Because of their intimate connection to the surrounding landscape headwater streams deliver nutrients and or- ganic material-like fallen leaves-to downstream regions sustaining aquatic life downstream.

What is a river profile in geography?
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. … The river’s load is fine sediment as erosion has broken down the rocks.
How does the profile of a river change 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. … As the river moves from the source to the mouth – both the depth of the river and the width of the river will both increase.

What does the long profile of a river show you?
What is a stream profile?
· includes the point of origin of the stream called the head the point of termination called the mouth and a decreasing gradient of the stream channel towards the mouth—examples of the mouth of the stream are the juncture of the stream and: another stream a pond or lake the ocean.
Where is the velocity of a stream generally faster at the headwaters or at the mouth?
Gradients are typically the lowest at a river’s mouth and highest at its headwaters. The higher the gradient the faster the stream flows.
