Title: Understanding the role of sediment waves and channel conditions over time and space

Author: Lisle, Thomas E.;

Date: 1997

Source: In: Sari Sommarstrom (ed). What is watershed stability? Proceedings, Sixth Biennial Watershed Management Conference. 23-25 October 1996 Lake Tahoe, California/Nevada. University of California, Water Resources Center Report No. 92, Davis, California. p. 57-67.

Publication Series: Miscellaneous Publication

Description: Abstract - Dynamic equilibrium in stream channels has traditionally been applied on the reach scale, where fluxes of water and sediment into a reach result in rapid but minor adjustments of channel dimensions, hydraulics or roughness (equilibrium), or aggradation and degradation (disequilibrium). Such an essentially one-dimensional spatial approach to sediment-channel interactions implicitly avoids a long standing and difficult problem: how do large inputs of sediment travel through channel systems and thereby distribute the fluxes to which channels respond at any time scale?

Keywords: PSW4351, channel conditions, sediment movement, dynamic equilibrium
