Abstract: The basis of a new mobile-bed fluvial modelling system is presented. It allows fully implicit calculation of both water movement and bed load of graded sediments. Armoring and sorting processes may be reproduced. Sensitivity tests show the adequacy of the basic choices and the sensitivity of the results to the decomposition of the qrading curve.
