bedload

Bedload refers to the larger particles, such as gravel, sand, or small stones, that are transported along the bottom of a river or stream by the moving water. These particles roll, slide, or bounce along the riverbed rather than being suspended in the water column. Bedload movement occurs mainly during higher water flows, shaping the riverbed over time. This process plays a key role in sculpting landscapes, creating river channels, and influencing sediment deposition. Understanding bedload helps engineers and environmentalists manage river health, prevent erosion, and protect aquatic habitats.
