Abstract

Rivers with constraints on the mobility of bed material, typically armoured channels with steeper than average relationship of bedload discharge to water discharge, may have an effective discharge occuring at higher stages and greater recurrence intervals than bankfull discharge. Bedload discharges were measured at 5 snow-melt dominated, gravel-bedded rivers in the northern Rocky Mountains, USA. Data indicate that, as the exponent of the bedload rating increases from typical to more steep values, effective discharge increases from near-bankfull discharge to, in this study, about 1.3 bankfull discharge. This represents about a doubling of the recurrence interval
