1. Stream Velocity

2. When the grade of a stream is greater, the speed of the water is ___________ .
When the speed of the water is greater, it is able to carry a __________ load of sediment.
When sediment is deposited at the mouth of a river, the _______ particles are closest to the river.
The ___________ particles will stay suspended in the water longer and travel farther.

3. Conclusions continued
Greater speed and greater flow both mean ____________ erosion.
When the flow of a stream is high, it carries sediment a _________ distance away from its mouth.
When the flow and speed of a stream are low, the eroded and deposited sediments form a pattern that is __________ in shape.

4. We can also look at erosion and deposition ALONG the river
When a stream’s grade its steep its shape is mostly straight

5. As the stream’s grade decreases . .
It begins to meander, looking for the easiest path.

6. At the mouth of a river, the speed of the water decreases dramatically, making the river drop its load of sediment. This is a constructive process that creates a DELTA.

7. A healthy delta: Selenga Delta, Lake Baikal, Russia

8. Mississippi River Delta: what a mess
