Description :
Bed-material load under a wide range of hydraulic conditions was sampled in a poorly sorted, sandy, gravel-bed river (Arbúcies, NE Spain) during 1991 and 1992. The Arbúcies data showed a marked scatter of bed-material discharges, reflecting the high variability of bedload rates as well as of suspended concentrations. Bed-material discharges were used to test 5 bedload and bed-material formulae. The degree of agreement between observed and predicted values varies greatly.
