sedimentstrøm
Sedimentstrøm, also known as sediment transport, refers to the movement of solid particles (sediment) by natural processes such as water flow, wind, or ice. This phenomenon is crucial in geomorphology, as it shapes landscapes over time. In fluvial systems, sediment transport occurs through processes like traction, saltation, and suspension. Traction involves the rolling or sliding of particles along the bed, while saltation describes the bouncing movement of particles in the flow. Suspension occurs when particles are lifted into the water column and carried along by the current. Wind can also transport sediment through processes like creep, saltation, and suspension, shaping dunes and desert landscapes. Glaciers transport sediment through processes like basal sliding and abrasion, contributing to the formation of moraines and other glacial landforms. Sediment transport plays a vital role in the Earth's surface processes, influencing erosion, deposition, and the evolution of landscapes. Understanding sediment transport is essential for various fields, including geology, hydrology, and environmental science.
