What defines the suspended load in a stream?

Suspended load in a stream is characterized by fine-grained sediment that remains in the water column during transportation. This includes particles such as silt and clay, which are small enough to be carried by the flow of water without settling to the bottom. This process is crucial in understanding sediment transport and river dynamics, as the suspended load contributes to the overall sediment budget, impacting water quality and habitat within aquatic ecosystems.

The distinction of the suspended load is particularly important because it affects how streams erode and deposit materials. Unlike heavier sediment that settles to the bottom, the suspended load can travel significant distances within the water, allowing streams to transport materials from one location to another efficiently. Understanding this concept helps in managing sediment-related issues in waterways, including erosion control and water clarity.
