Cooperative Research Project Final report: Scour and Fill of Spawning Gravels in a Small Coastal Stream of Northwestern California
Yee CS. 1981. Cooperative Research Project Final report: Scour and Fill of Spawning Gravels in a Small Coastal Stream of Northwestern California
Excerpts: " Excessive and inopportune scouring of spawning gravel beds can be detrimental to salmonid eggs and the subsequent alevins. Habitat may also be adversely effected by excessive scour of riffles and filling of pools. This study investigates the spatial and temporal variable in gravel movement on three spawning riffles over two winter seasons. this study attempts to provide answers to the following questions: 1) What is the frequency of spawning gravel bed movement? 2) During which months is movement most likely to occur? 3) Where does gravel movement most likely occur on a riffle?"
