Abstract<\/strong><\/p>\n

When a channel is overloaded with sediment, an aggradation wave propagates with a certain celerity along the reach. Estimation of the local aggradation depth and of the celerity of propagation are important for hazard assessment and emergency planning. In the current project the aggradation process is studied using a variety of approaches to meet different objectives. First, the celerity of propagation of aggradation wave is investigated by performing an appropriate experimental campaign. Furthermore, considering that morphological processes are modeled by differential equations, the eigenvalues of the latter\u2019s system represent the celerity of propagation of small perturbations. With reference to the laboratory experiments with temporally and spatially detailed measurements, our investigation shows how the celerity of propagation of aggradation wave and the eigenvalues correlate with one another, while their values differ by orders of magnitude. Second, the aggradation process studied experimentally are reproduced with corresponding numerical simulations in one-dimensional conditions, demonstrating that the presence of sediment transport in a flow may result in an increase in the equivalent Manning\u2019s coefficient. Third, the aggradation process is also simulated using a linear diffusion equation. In this context, an analytical solution for the diffusion equation is employed in the performed aggradation experiments, revealing that a constant value for the diffusion coefficient is enough to reproduce the bed evolution within an experiment.<\/p>\n
