The flow of water suspends particles into the water column as they move downstream, or simply push them along the bottom of a waterway.
Explanation:
The combination of organic and inorganic material, that gets carried away by water, wind or ice is referred as Sediment.
Erosion and weathering causes the mineral sediment. Organic sediment is caused by debris and decomposing substances.
When the flow of water slows down or stops, the heavy particles that can no longer be carried gets settled down to the bottom of the water body.
Sediment is essential for the development of aquatic ecosystems. The greater the flow of water, the more particles will get transported.
