Document Summary
Fluvial systems like all natural systems have characteristic process and produce recognizable landforms. The term river is applied to a trunk or main stream or an entire river system. Stream is a more general term not necessarily related to size. Isolation and gravity power the hydrologic cycle and are the driving forces of fluvial systems. Water dislodges , dissolves or removes surface material in the erosion process. Streams produce fluvial erosion in which weather sediment is picked up for transport to new locations. A stream is a mixture of water and solids are carried in suspension by mechanical transport and in dissolved solutions. Materials are laid down by another process, deposition. Alluvium is the general term for the clay, silt , sand, gravel and mineral fragments deposited by running water as sorted or semi-sorted sediment on a floodplain, delta or streambed. Base level is a level below which a stream cannot erode its valley.
