Sedimentflöde, often translated as sediment flow or sediment transport, refers to the movement of solid particles, such as sand, silt, and clay, through a fluid medium, typically water. This process is a fundamental aspect of geomorphology and plays a crucial role in shaping landscapes. Sediment flows can occur in various environments, including rivers, oceans, and even on land during debris flows. The velocity and density of the fluid, along with the size, shape, and concentration of the sediment particles, all influence the dynamics of sediment transport.

There are several mechanisms by which sediment is transported. Suspension involves fine particles being carried along within the fluid column. Saltation describes the bouncing or hopping motion of larger particles along the bed. Bedload transport, the slowest form, involves particles rolling or sliding along the channel or seafloor. The energy of the flow dictates which of these transport modes will dominate. Understanding sedimentflöde is vital for disciplines such as hydrology, coastal engineering, and environmental science, as it impacts river channel morphology, sediment deposition in reservoirs, coastal erosion, and the distribution of nutrients and pollutants.
