2018年6月6日 · Rivers and streams have a great impact on both the local landscape and our own lives. Flowing water continually erodes the land it runs through, and over millions of years the topography of the land can be greatly changed (notice how deep the Grand Canyon gorge is).
Rivers transport three main materials downstream – water, sediment, and organic material. The abiotic components – water and sediment – most directly affect the shape of the river channel [Fluvial Geomorphology]. A change in either the flow of water or the sediment load of the river can lead to increased deposition or erosion.
