Fluvial sediments are particles of rock, soil, and organic material that are transported and deposited by rivers and streams. These sediments can form various landforms, including deltas, alluvial fans, and river terraces. Fluvial sediments are essential in understanding sedimentary processes, river dynamics, and the reconstruction of past environmental conditions.
