Inception of sediment transport on steep slopes : preliminary report / Y. Lam Lau and Peter Engel. : En13-5/97-70E-PDF
"Effective aquatic ecosystem protection requires better understanding of the sediment transport process at the bed of steep streams. Movement of gravel and the intrusion of sediment fines into the gravel bed greatly restrict transport of dissolved oxygen into and through the bed substrate. The ability of interstitial water flow to sustain substrate organisms and remove metabolic waste is thus reduced. These factors have significant implications for maintaining river habitat functions and point to the importance of continuing research on physical river processes. This report shows that present knowledge on the beginning of sediment transport in steep gravel bed needs to be expanded to provide design information for channel maintenance and management over a wide range of practical flow conditions"--Management perspective, p. i.
