River Valleys and Graded River

Options:

1. The channel gradient decreases
2. The valley floor decreases in height
3. The sediment load increases
4. The river profile becomes shallower

Correct Answer

Options:

1. The channel gradient increases
2. The valley floor decreases in height
3. The graded curve of the river gets disturbed
4. The river profile becomes deeper

Correct Answer

Options:

1. Active sea waves
2. Decrease in channel gradient
3. Increase in sedimentation
4. Increase in velocity

Correct Answer

Options:

1. The master stream becomes able to transport additional sediment load downstream
2. The juvenile tributary stream becomes unable to transport sediment load downstream
3. The river regrades its curve at a lower elevation
4. Sedimentation in the downstream section from the confluence results in a decrease in channel gradient in the upstream section

Correct Answer

Options:

1. When sediment load equals the transporting capacity of the river
2. When the river becomes wider
3. When the river becomes deeper
4. When the valley floor decreases in height
