Summary Whereas effective discharge ( Q eff ) in mountain streams is commonly associated with a moderate flow such as bankfull discharge ( Q bf ), this study found that the maximum discharge ( Q max ), and not bankfull discharge, is the channel forming or effective flow for gravel transport in plane-bed streams where partial bed mobility causes steep gravel transport rating curves. Q eff may approach bankfull flow in some step-pool channels where gravel moves over a static cobble/boulder bed… CONTINUE READING
