• Stream deposition:
• Where does stream
deposition occur?
• At mouth of stream- delta
• Along inside bends- point
bars
• On the bottom
• When does deposition
occur?
• When the speed of the water
decreases
Speed of water in streams:
• Straight section: Fastest in
center
• Meanders: Fastest on
outside bend
• How does deposition occur?
• Vertical sorting- BIG,
DENSE, ROUND sediments
drop first and fastest- on
bottom. Small, less dense,
flat- on top
• vertical sorting animation
• settling rates animation
• Horizontal sorting- BIG,
DENSE sediments dropped
closest to shore. Small, less
dense farther from shore
• horizontal sorting animation
