Keywords: Sediment transport; Friction coefficient; 1D model; Bed forms

Abstract: The increase of the head losses due to bed forms is interpreted in the U-curves (ratio of Strickler coefficients versus ratio of bottom shear stresses) and of S-curves (Strickler coefficient versus discharge). This effect is stronger at dominant discharge. It can lead to a rise of water level much higher than the final topographical change. For the presented example of a reach of River Rhone near Bourg les Valence, this rise is estimated over 1 m for the dominant discharge of about 1200 m 3 /s.
