Orru, C. (author), Chavarrias Borras, V. (author), Ferrara, V. (author), Stecca, G. (author), Blom, A. (author)A flume experiment was conducted to examine the evolution of a sand-gravel reach under a lack of sediment supply. A bed composed of a bimodal sediment mixture was installed with a uniform slope and an gradual fining pattern. At the upstream end of the flume the initial bed consisted of 100% gravel, which decreased stepwise (10% steps) in...conference paper 2015

Stecca, G. (author), Blom, A. (author)Modelling the morphodynamic evolution of rivers due to flow-driven sediment transport requires the adoption of a flow model, such as the shallow water equations, and a conservation equation for sediment mass (the Exner equation). When dealing with mixtures of grain sizes, one can account for the interaction among sediment transport, bed level...conference paper 2013
