Erosion by Streams Sediments are carried as the following loads: dissolved, suspended, and bed. Particles that are too large to be carried as suspended loads are bumped and pushed along the stream bed, called bed load. Bed load sediments do not move continuously, but rather in intermittent movements, called saltation.

Stream Deposition

• Bars.
• Floodplains.
• Alluvial fans.
• Deltas.
• Topset beds are nearly horizontal layers of sediment deposited by the distributaries as they flow away from the mouth and toward the delta front.
• Braided streams.
• Meanders and oxbow lakes.

Sediment is solid material that is moved and deposited in a new location. Sediment can consist of rocks and minerals, as well as the remains of plants and animals. Erosion is the removal and transportation of rock or soil. Erosion can move sediment through water, ice, or wind.

Dissolved and suspended load move with the natural stream flow, while the heavier bed load rolls across the floor of the stream.

The main agents by which sedimentary materials are moved include gravity (gravity transport), river and stream flow, ice, wind, and estuarine and ocean currents. Running water and wind are the most widespread transporting agents.

Water, wind, ice and gravity are the main agents for sediment transport. Gravity can act alone or associated to other agents, such as water, thus constituting the main sediment transport agent in nature.

Sediment in a Sentence ?

1. The apple cider had sediment in the bottom as part of the natural settling process.
2. We collected water from the ocean in a bottle to study the sediment.
3. We had to rinse the mussels because they had sediment from the ocean on them.

(sedɪmənt ) Word forms: plural sediments. variable noun. Sediment is solid material that settles at the bottom of a liquid, especially earth and pieces of rock that have been carried along and then left somewhere by water, ice, or wind.

Local Examples of Sediment Pollution Excessive sedimentation from logging on the proposed Curry mine site. Sediment from logging on the site of the proposed Curry mine creating a plume in the Yough Excessive sediment in Champion Creek as a result of rain and snowmelt.

Weathering wears rocks at the Earth’s surface down into smaller pieces. The small fragments are called sediments. Running water, ice, and gravity all transport these sediments from one place to another by erosion. During sedimentation, the sediments are laid down or deposited.

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
