Recent Changes In Channel Stored Sediment Redwood Creek California Classic Reprint

Excerpt from Recent Changes in Channel-Stored Sediment, Redwood Creek, California Historically, geomorphologists have studied both hillslope erosion processes and sediment transport in rivers, but few studies have quantified a link between these two areas the storage component of channels. Channels may temporarily store sediment derived from hillslope erosion before transporting it out of the system. The quantity of sediment and its residence time varies with the type of system. Streams in steep mountainous terrain store little sediment for relatively brief periods of time, whereas rivers in broad alluvial valleys store vast quantities of sediment in their floodplains for thousands of years. As a result, channel storage may modify the effects of hillslope erosion on sediment yield measurements made at a point downstream. Thus sediment yield measurements may not truly reflect current rates of hillslope erosion in a watershed. Nevertheless, changes in sediment yield are often used to detect changes in rates of hillslope erosion due to land use modifications. In basins where channels store a significant portion of sediment in transport, it is not valid to assume a constant relation between hillslope erosion and sediment yield because the amount of alluvial storage can change in response to modifications in a watershed.
